Cucumber ​

This documentation describes the technical aspects of our cucumber test suite.

tl;dr ​

Run the Cucumber tests with:

bash
$ npm test

Single OSRM Configuration ​

An OSRM configuration consists of a routing algorithm and a data load method. OSRM currently supports the routing algorithms:

  • ch (Contraction Hierarchy), and
  • mld (Multi-Level-Dijkstra)

and the data load methods:

  • directly (load the files into memory),
  • mmap (use memory mapped files), and
  • datastore (use shared memory).

To test all scenarios with a single OSRM configuration, say:

bash
$ npx cucumber-js -p home -p mld -p mmap --parallel 8 --fail-fast

Explanations follow:

Profiles ​

Profiles are chosen with the -p commandline argument. Cucumber profiles allow you to change multiple configuration items with just one commandline argument. If you set more than one profile they are all merged into one configuration.

Note: Cucumber profiles should not be confused with OSRM profiles. Cucumber profiles are defined in cucumber.mjs. OSRM profiles reside in the profiles/*.lua files.

Our implementation offers following stock profiles. You should always use one base profile followed by zero or more additional profiles.

Name
homeBase profile to use on a developer machine
githubBase profile to use on the github CI server
chAdditional profile that selects the CH algorithm
mldAdditional profile that selects the MLD algorithm
mmapAdditional profile that selects the mmap data load method
directlyAdditional profile that selects the directly data load method
datastoreAdditional profile that selects the datastore data load method
stressAdditional profile that selects only @stress tests
todoAdditional profile that selects only @todo tests
allAdditional profile that selects all tests

Arguments ​

Here is a description of all arguments you can pass to Cucumber. The interesting ones probably are: --fail-fast, --format, --parallel, and --tags.

Note: when using --parallel N make sure there are N contiguous free ports at the configured port number (eg. at ports 5000--5000+N).

All OSRM Configurations ​

We provide a shortcut to run all 6 configurations:

bash
$ npm test

This is how the tests are run on the CI server. You can pass the same arguments as mentioned above.

Cache ​

To speed up subsequent runs with the same parameters, the files generated by Cucumber and the by the OSRM extraction chain are held in a cache directory. This cache is located by default in test/cache and should be cleaned periodically:

bash
$ rm -rf test/cache

Configuration ​

The whole configuration is done in cucumber.mjs. You can either edit worldParameters in cucumber.mjs or use environment variables to override single defaults.

worldParametersEnvironment VariableDefaults to
CUCUMBER_TIMEOUT5000Scenario timeout in ms.
httpTimeoutCUCUMBER_HTTP_TIMEOUT2000HTTP timeout in ms.
testPathCUCUMBER_TEST_PATHtestThe test directory
profilesPathCUCUMBER_PROFILES_PATHprofilesThe profiles directory
logsPathCUCUMBER_LOGS_PATHtest/logsThe logs directory
cachePathCUCUMBER_CACHE_PATHtest/cacheThe cache directory
buildPathOSRM_BUILD_DIRbuildPath to the binaries
loadMethodOSRM_LOAD_METHODdatastoreData load method
algorithmOSRM_ALGORITHMchRouting algorithm
ipOSRM_IP127.0.0.1IP Address
portOSRM_PORT5000IP Port

The default Cucumber timeout can be changed by setting the environment variable CUCUMBER_TIMEOUT. This is discouraged, because the default timeout of 5 seconds is plenty for the problem sizes we are dealing with. The probable reasons for a test timing out are that osrm-routed died or that sync between osrm-datastore and osrm-routed was lost.

Other environment variables ​

OSRM_RASTER_SOURCE is set by 'Given the raster source' and is supposed to be read back in your profiles/*.lua profile by os.getenv('OSRM_RASTER_SOURCE').

OSRM_PROFILE See: Pull Request #4516

Tags ​

Single scenarios or whole feature files can be tagged. Tag names can be selected arbitrarily although it is best to conform to the tags already used. Eg. the tag @guidance can be used to run only those tests related to the guidance feature:

bash
$ npm test -- --tags @guidance

We also support following special tags:

TagA scenario thus tagged ...
@isolatedwill not run while any other scenario is running in parallel
@with_(datastore|directly|mmap)will be executed iff the load method matches
@no_(datastore|directly|mmap)will be executed unless the load method matches
@with_(ch|mld)will be executed iff the algorithm matches
@no_(ch|mld)will be executed unless the algorithm matches
@with_(linux|darwin|win32)will be executed iff the OS matches
@no_(linux|darwin|win32)will be executed unless the OS matches

A test that calls osrm-datastore --spring-clean should not run concurrently with any other test, thus the tag @isolated should be applied. A test that runs or kills osrm-routed should not run while testing the datastore load method, and thus should be labeled with the tag @no_datastore.

Developing / Debugging guidance code ​

When changing guidance code, it is easy to introduce problems somewhere in the network. To get a better feeling of how your changes impact the OSRM experience, we offer ways of generating geojson output to inspect (e.g. with Mapbox Studio). When you do changes, make sure to inspect a few areas for the impact of the changes.

How to use GeoJson-Debugging ​

This is a short guide to describe usage of our GeoJson debug logging mechanism. It is synchronized to guarantee thread-safe logging.

Outputting into a single file ​

To use it, the inclusion of geojson_debug_logger.hpp geojson_debug_policies.hpp from the util directory is required.

Geojson debugging requires a few simple steps to output data into a feature collection.

  • Create a Scoped Guard that lives through the process and provide it with all required datastructures (it needs to span the lifetime of all your logging efforts)
  • At the location of the output, simply call Write with your own parameters.

A guard (ScopedGeojsonLoggerGuard) requires a logging policy. Per default we provide a way of printing out node-ids as coordinates.

The initialisation to do so looks like this: util::ScopedGeojsonLoggerGuard<util::NodeIdVectorToLineString> geojson_guard( "debug.geojson", data-for-conversion); Make sure to give the guard a name, so it actually gets a lifetime.

The field data-for-conversion can be an arbitrary long set of features and needs to match the parameters used for constructing our policy (in this case util::NodeIdVectorToLineString).

The policy itself offers a operator() accepting a vector of NodeID.

For outputting data into our file (debug.geojson), we simply need to call the matching logging routine of the guard: util::ScopedGeojsonLoggerGuard<util::NodeIdVectorToLineString>::Write(list_of_node_ids); (or guard.Write(list_of_node_ids) if you created an instance).

Possible Scopeguard Location ​

Think of the scopeguard as you would do of any reference. If you want to access logging during a call, the guard object must be alive and valid.

As an example: a good location to create a scopeguard to log decisions in the edge-based-graph-factory would be right before we run it (here). If you put util::ScopedGeojsonLoggerGuard<util::NodeIdVectorToLineString> geojson_guard( "debug.geojson", node_coordinate_vector); at that location, you can then print util::ScopedGeojsonLoggerGuard<util::NodeIdVectorToLineString>::Write(list_of_node_ids); anywhere within the edge-based-graph-factory.

This location would enable calls for all guidance related pre-processing which is called in the edge-based-graph-factory. Logging any turn-handler decisions, for example, would now be possible.

Limitations ​

GeoJson debugging requires a single GeoJsonGuard (ScopedGeojsonLoggerGuard) for each desired output file. For each set of template parameters, only the most recent guard will actually produce output.

util::ScopedGeojsonLoggerGuard<util::NodeIdVectorToLineString> geojson_guard( "debug.geojson", data-for-conversion);

util::ScopedGeojsonLoggerGuard<util::NodeIdVectorToLineString> geojson_guard( "debug-2.geojson", data-for-conversion);

Will not provide a way to write into two files, but only debug-2 will actually contain features.

We cannot nest these calls.

If we want to use the same policy for multiple files, we need to use different template parameters both for the logger and the guard.

util::ScopedGeojsonLoggerGuard<util::NodeIdVectorToLineString,0> geojson_guard( "debug.geojson", data-for-conversion);

util::ScopedGeojsonLoggerGuard<util::NodeIdVectorToLineString,1> geojson_guard( "debug-2.geojson", data-for-conversion);

as well as,

util::ScopedGeojsonLoggerGuard<util::NodeIdVectorToLineString,0>::Write(list_of_node_ids);

util::ScopedGeojsonLoggerGuard<util::NodeIdVectorToLineString,1>::Write(list_of_node_ids);

OSRM HTTP server ​

The built-in HTTP server is a basic HTTP/1.0 server that supports a 'keep-alive' extension. Persistent connections are limited to 512 requests per connection and allow no more than 5 seconds between requests.

General options ​

All OSRM HTTP requests use a common structure.

The following syntax applies to all services, except as noted.

Requests ​

GET
/{service}/{version}/{profile}/{coordinates}[.{format}]?option=value&option=value
ParameterDescription
serviceOne of the following values: route, nearest, table, match, trip, tile
versionVersion of the protocol implemented by the service. v1 for all OSRM 5.x installations
profileMode of transportation, is determined statically by the Lua profile that is used to prepare the data using osrm-extract. Typically car, bike or foot if using one of the supplied profiles.
coordinatesString of format {longitude},{latitude};{longitude},{latitude}[;{longitude},{latitude} ...] or polyline({polyline}) or polyline6({polyline6}).
formatjson or flatbuffers. This parameter is optional and defaults to json.

Passing any option=value is optional. polyline follows Google's polyline format with precision 5 by default and can be generated using this package.

To pass parameters to each location some options support an array-like encoding:

Request options

OptionValuesDescription
bearings{bearing};{bearing}[;{bearing} ...]Limits the search to segments with given bearing in degrees towards true north in a clockwise direction.
radiuses{radius};{radius}[;{radius} ...]Limits the search to given radius in meters.
generate_hintstrue (default), falseAdds a Hint to the response which can be used in subsequent requests, see hints parameter.
hints{hint};{hint}[;{hint} ...]Hint from previous request to derive position in street network.
approaches{approach};{approach}[;{approach} ...]Restrict the direction on the road network at a waypoint, relative to the input coordinate.
exclude{class}[,{class}]Additive list of classes to avoid, the order does not matter.
snappingdefault (default), anyDefault snapping avoids is_startpoint (see profile) edges, any will snap to any edge in the graph
skip_waypointstrue, false (default)Removes waypoints from the response. Waypoints are still calculated, but not serialized. Could be useful in case you are interested in some other part of the response and do not want to transfer waste data.

Where the elements follow the following format:

ElementValues
bearing{value},{range} integer 0 .. 360,integer 0 .. 180
radiusdouble >= 0 or unlimited (default)
hintBase64 string
approachcurb, opposite or unrestricted (default)
classA class name determined by the profile or none.
{option}={element};{element}[;{element} ... ]

The number of elements must match exactly the number of locations (except for generate_hints and exclude). If you don't want to pass a value but instead use the default you can pass an empty element.

Example: 2nd location uses the default value for option:

{option}={element};;{element}

Responses ​

Code ​

Every response object has a code property containing one of the strings below or a service dependent code:

TypeDescription
OkRequest could be processed as expected.
InvalidUrlURL string is invalid.
InvalidServiceService name is invalid.
InvalidVersionVersion is not found.
InvalidOptionsOptions are invalid.
InvalidQueryThe query string is syntactically malformed.
InvalidValueThe successfully parsed query parameters are invalid.
NoSegmentOne of the supplied input coordinates could not snap to the street segment.

Match service ​

Map matching matches/snaps given GPS points to the road network in the most plausible way. Please note the request might result in multiple sub-traces. Large jumps in the timestamps (> 60s) or improbable transitions lead to trace splits if a complete matching could not be found. The algorithm might not be able to match all points. Outliers are removed if they can not be matched successfully.

GET
/match/v1/{profile}/{coordinates}?steps={true|false}&geometries={polyline|polyline6|geojson}&overview={simplified|full|false}&annotations={true|false}

In addition to the general options the following options are supported for this service:

OptionValuesDescription
stepstrue, false (default)Returned route steps for each route
geometriespolyline (default), polyline6, geojsonReturned route geometry format (influences overview and per step)
annotationstrue, false (default), nodes, distance, duration, datasources, weight, speedReturns additional metadata for each coordinate along the route geometry.
overviewsimplified (default), full, false, by_legsAdd overview geometry either full, simplified according to highest zoom level it could be displayed on, not at all, or split by leg.
timestamps{timestamp};{timestamp}[;{timestamp} ...]Timestamps for the input locations in seconds since UNIX epoch. Timestamps need to be monotonically increasing.
radiuses{radius};{radius}[;{radius} ...]Standard deviation of GPS precision used for map matching. If applicable use GPS accuracy.
gapssplit (default), ignoreAllows the input track splitting based on huge timestamp gaps between points.
tidytrue, false (default)Allows the input track modification to obtain better matching quality for noisy tracks.
waypoints{index};{index};{index}...Treats input coordinates indicated by given indices as waypoints in returned Match object. Default is to treat all input coordinates as waypoints.
ParameterValues
timestampinteger seconds since UNIX epoch
radiusdouble >= 0 (default 5m)

The radius for each point should be the standard error of the location measured in meters from the true location. Use Location.getAccuracy() on Android or CLLocation.horizontalAccuracy on iOS. This value is used to determine which points should be considered as candidates (larger radius means more candidates) and how likely each candidate is (larger radius means far-away candidates are penalized less). The area to search is chosen such that the correct candidate should be considered 99.9% of the time (for more details see this ticket).

Response

  • code if the request was successful Ok otherwise see the service dependent and general status codes.
  • tracepoints: Array of Waypoint objects representing all points of the trace in order. If the tracepoint was omitted by map matching because it is an outlier, the entry will be null. Each Waypoint object has the following additional properties:
    • matchings_index: Index to the Route object in matchings the sub-trace was matched to.
    • waypoint_index: Index of the waypoint inside the matched route.
    • alternatives_count: Number of probable alternative matchings for this tracepoint. A value of zero indicates that this point was matched unambiguously. Split the trace at these points for incremental map matching.
  • matchings: An array of Route objects that assemble the trace. Each Route object has the following additional properties:
    • confidence: Confidence of the matching. float value between 0 and 1. 1 is very confident that the matching is correct.

In case of error the following codes are supported in addition to the general ones:

TypeDescription
NoMatchNo matchings found.

All other properties might be undefined.

Trip service ​

The trip plugin solves the Traveling Salesman Problem using a greedy heuristic (farthest-insertion algorithm) for 10 or more waypoints and uses brute force for less than 10 waypoints. The returned path does not have to be the fastest one. As TSP is NP-hard it only returns an approximation. Note that all input coordinates have to be connected for the trip service to work.

GET
/trip/v1/{profile}/{coordinates}?roundtrip={true|false}&source={any|first}&destination={any|last}&steps={true|false}&geometries={polyline|polyline6|geojson}&overview={simplified|full|false}&annotations={true|false}

In addition to the general options the following options are supported for this service:

OptionValuesDescription
roundtriptrue (default), falseReturned route is a roundtrip (route returns to first location)
sourceany (default), firstReturned route starts at any or first coordinate
destinationany (default), lastReturned route ends at any or last coordinate
stepstrue, false (default)Returned route instructions for each trip
annotationstrue, false (default), nodes, distance, duration, datasources, weight, speedReturns additional metadata for each coordinate along the route geometry.
geometriespolyline (default), polyline6, geojsonReturned route geometry format (influences overview and per step)
overviewsimplified (default), full, false, by_legsAdd overview geometry either full, simplified according to highest zoom level it could be displayed on, not at all, or split by leg.

Fixing Start and End Points

It is possible to explicitly set the start or end coordinate of the trip. When the source is set to first, the first coordinate is used as the start coordinate of the trip in the output. When the destination is set to last, the last coordinate will be used as the destination of the trip in the returned output. If you specify any, any of the coordinates can be used as the first or last coordinate in the output.

However, if source=any&destination=any the returned round-trip will still start at the first input coordinate by default.

Currently, not all combinations of roundtrip, source, and destination are supported. Right now, the following combinations are possible:

roundtripsourcedestinationsupported
truefirstlastyes
truefirstanyyes
trueanylastyes
trueanyanyyes
falsefirstlastyes
falsefirstanyyes

Tile service ​

This service generates Mapbox Vector Tiles that can be viewed with a vector-tile capable slippy-map viewer. The tiles contain road geometries and metadata that can be used to examine the routing graph. The tiles are generated directly from the data in-memory, so are in sync with actual routing results, and let you examine which roads are actually routable, and what weights they have applied.

GET
/tile/v1/{profile}/tile({x},{y},{zoom}).mvt

The x, y, and zoom values are the same as described at https://wiki.openstreetmap.org/wiki/Slippy_map_tilenames, and are supported by vector tile viewers like Mapbox GL JS.

Example request ​

bash
# This fetches a Z=13 tile for downtown San Francisco:
+curl 'http://router.project-osrm.org/tile/v1/car/tile(1310,3166,13).mvt'

Example response ​

example rendered tilehttp://map.project-osrm.org/debug/#14.33/52.5212/13.3919

The response object is either a binary encoded blob with a Content-Type of application/x-protobuf, or a 404 error. Note that OSRM is hard-coded to only return tiles from zoom level 12 and higher (to avoid accidentally returning extremely large vector tiles).

Vector tiles contain two layers:

speeds layer:

PropertyTypeDescription
speedintegerthe speed on that road segment, in km/h
is_smallbooleanwhether this segment belongs to a small (< 1000 node) strongly connected component
datasourcestringthe source for the speed value (normally lua profile unless you're using the traffic update feature, in which case it contains the stem of the filename that supplied the speed value for this segment
durationfloathow long this segment takes to traverse, in seconds. This value is to calculate the total route ETA.
weight integerhow long this segment takes to traverse, in units (may differ from duration when artificial biasing is applied in the Lua profiles). ACTUAL ROUTING USES THIS VALUE.
namestringthe name of the road this segment belongs to
ratefloatthe value of length/weight - analogous to speed, but using the weight value rather than duration, rounded to the nearest integer
is_startpointbooleanwhether this segment can be used as a start/endpoint for routes

turns layer:

PropertyTypeDescription
bearing_inintegerthe absolute bearing that approaches the intersection. -180 to +180, 0 = North, 90 = East
turn_angleintegerthe angle of the turn, relative to the bearing_in. -180 to +180, 0 = straight ahead, 90 = 90-degrees to the right
costfloatthe time we think it takes to make that turn, in seconds. May be negative, depending on how the data model is constructed (some turns get a "bonus").
weightfloatthe weight we think it takes to make that turn. May be negative, depending on how the data model is constructed (some turns get a "bonus"). ACTUAL ROUTING USES THIS VALUE
typestringthe type of this turn - values like turn, continue, etc. See the StepManeuver for a partial list, this field also exposes internal turn types that are never returned with an API response
modifierstringthe direction modifier of the turn (left, sharp left, etc)

StepManeuver object ​

Properties

  • location: A [longitude, latitude] pair describing the location of the turn.
  • bearing_before: The clockwise angle from true north to the direction of travel immediately before the maneuver. Range 0-359.
  • bearing_after: The clockwise angle from true north to the direction of travel immediately after the maneuver. Range 0-359.
  • type A string indicating the type of maneuver. new identifiers might be introduced without API change Types unknown to the client should be handled like the turn type, the existence of correct modifier values is guaranteed.
typeDescription
turna basic turn into the direction of the modifier
new nameno turn is taken/possible, but the road name changes. The road can take a turn itself, following modifier.
departindicates the departure of the leg
arriveindicates the destination of the leg
mergemerge onto a street (e.g. getting on the highway from a ramp, the modifier specifies the direction of the merge)
rampDeprecated. Replaced by on_ramp and off_ramp.
on ramptake a ramp to enter a highway (direction given my modifier)
off ramptake a ramp to exit a highway (direction given my modifier)
forktake the left/right side at a fork depending on modifier
end of roadroad ends in a T intersection turn in direction of modifier
use laneDeprecated replaced by lanes on all intersection entries
continueTurn in direction of modifier to stay on the same road
roundabouttraverse roundabout, if the route leaves the roundabout there will be an additional property exit for exit counting. The modifier specifies the direction of entering the roundabout.
rotarya traffic circle. While very similar to a larger version of a roundabout, it does not necessarily follow roundabout rules for right of way. It can offer rotary_name and/or rotary_pronunciation parameters (located in the RouteStep object) in addition to the exit parameter (located on the StepManeuver object).
roundabout turnDescribes a turn at a small roundabout that should be treated as a normal turn. The modifier indicates the turn direction. Example instruction: At the roundabout turn left.
notificationnot an actual turn but a change in the driving conditions. For example the travel mode or classes. If the road takes a turn itself, the modifier describes the direction
exit roundaboutDescribes a maneuver exiting a roundabout (usually preceded by a roundabout instruction)
exit rotaryDescribes the maneuver exiting a rotary (large named roundabout)

Please note that even though there are new name and notification instructions, the mode and name can change between all instructions. They only offer a fallback in case nothing else is to report.

  • modifier An optional string indicating the direction change of the maneuver.
modifierDescription
uturnindicates the reversal of direction
sharp righta sharp right turn
righta normal turn to the right
slight righta slight turn to the right
straightno relevant change in direction
slight lefta slight turn to the left
lefta normal turn to the left
sharp lefta sharp turn to the left

The list of turns without a modifier is limited to: depart/arrive. If the source/target location is close enough to the depart/arrive location, no modifier will be given.

The meaning depends on the type property.

typeDescription
turnmodifier indicates the change in direction accomplished through the turn
depart/arrivemodifier indicates the position of departure point and arrival point in relation to the current direction of travel
  • exit An optional integer indicating the number of the exit to take. The property exists for the roundabout / rotary property: Number of the roundabout exit to take. If an exit is undefined the destination is on the roundabout.

New properties (potentially depending on type) may be introduced in the future without an API version change.

A Lane represents a turn lane at the corresponding turn location.

Properties

  • indications: an indication (e.g. marking on the road) specifying the turn lane. A road can have multiple indications (e.g. an arrow pointing straight and left). The indications are given in an array, each containing one of the following types. Further indications might be added on without an API version change.
valueDescription
noneNo dedicated indication is shown.
uturnAn indication signaling the possibility to reverse (i.e. fully bend arrow).
sharp rightAn indication indicating a sharp right turn (i.e. strongly bend arrow).
rightAn indication indicating a right turn (i.e. bend arrow).
slight rightAn indication indicating a slight right turn (i.e. slightly bend arrow).
straightNo dedicated indication is shown (i.e. straight arrow).
slight leftAn indication indicating a slight left turn (i.e. slightly bend arrow).
leftAn indication indicating a left turn (i.e. bend arrow).
sharp leftAn indication indicating a sharp left turn (i.e. strongly bend arrow).
  • valid: a boolean flag indicating whether the lane is a valid choice in the current maneuver

Example ​

json
{
+    "indications": ["left", "straight"],
+    "valid": false
+}

Intersection object ​

An intersection gives a full representation of any cross-way the path passes by. For every step, the very first intersection (intersections[0]) corresponds to the location of the StepManeuver. Further intersections are listed for every cross-way until the next turn instruction.

Properties

  • location: A [longitude, latitude] pair describing the location of the turn.
  • bearings: A list of bearing values (e.g. [0,90,180,270]) that are available at the intersection. The bearings describe all available roads at the intersection. Values are between 0-359 (0=true north)
  • classes: An array of strings signifying the classes (as specified in the profile) of the road exiting the intersection.
  • entry: A list of entry flags, corresponding in a 1:1 relationship to the bearings. A value of true indicates that the respective road could be entered on a valid route. false indicates that the turn onto the respective road would violate a restriction.
  • in: index into bearings/entry array. Used to calculate the bearing just before the turn. Namely, the clockwise angle from true north to the direction of travel immediately before the maneuver/passing the intersection. Bearings are given relative to the intersection. To get the bearing in the direction of driving, the bearing has to be rotated by a value of 180. The value is not supplied for depart maneuvers.
  • out: index into the bearings/entry array. Used to extract the bearing just after the turn. Namely, The clockwise angle from true north to the direction of travel immediately after the maneuver/passing the intersection. The value is not supplied for arrive maneuvers.
  • lanes: Array of Lane objects that denote the available turn lanes at the intersection. If no lane information is available for an intersection, the lanes property will not be present.

Example ​

json
{
+    "location":[13.394718,52.543096],
+    "in":0,
+    "out":2,
+    "bearings":[60,150,240,330],
+    "entry":["false","true","true","true"],
+    "classes": ["toll", "restricted"],
+    "lanes":{
+        "indications": ["left", "straight"],
+        "valid": false
+    }
+}

Waypoint object ​

The object is used to describe the waypoint on a route.

Properties

  • name Name of the street the coordinate snapped to
  • location Array that contains the [longitude, latitude] pair of the snapped coordinate
  • distance The distance, in meters, from the input coordinate to the snapped coordinate
  • hint Unique internal identifier of the segment (ephemeral, not constant over data updates) This can be used on subsequent requests to significantly speed up the query and to connect multiple services. E.g. you can use the hint value obtained by the nearest query as hint values for route inputs.

Example ​

json
{
+   "hint" : "KSoKADRYroqUBAEAEAAAABkAAAAGAAAAAAAAABhnCQCLtwAA_0vMAKlYIQM8TMwArVghAwEAAQH1a66g",
+   "distance" : 4.152629,
+   "name" : "Friedrichstraße",
+   "location" : [
+      13.388799,
+      52.517033
+   ]
+}

Flatbuffers format ​

The default response format is json, but OSRM supports binary flatbuffers format, which is much faster in serialization/deserialization, comparing to json.

The format itself is described in message descriptors, located at include/engine/api/flatbuffers directory. Those descriptors could be compiled to provide protocol parsers in Go/Javascript/Typescript/Java/Dart/C#/Python/Lobster/Lua/Rust/PHP/Kotlin. Precompiled protocol parser for C++ is supplied with OSRM.

Flatbuffers format provides exactly the same data, as json format with a slightly different layout, which was optimized to minimize in-transfer size.

Root object ​

Root object is the only object, available from a 'raw' flatbuffers buffer. It can be constructed with a following call:

     auto osrm = osrm::engine::api::fbresult::GetFBResult(some_input_buffer);
+

Properties

  • error: bool Marks response as erroneous. An erroneous response should include the code fieldset, all the other fields may not be present.
  • code: Error Error description object, only present, when error is true
  • waypoints: [Waypoint] Array of Waypoint objects. Should present for every service call, unless skip_waypoints is set to true. Table service will put sources array here.
  • routes: [RouteObject] Array of RouteObject objects. May be empty or absent. Should present for Route/Trip/Match services call.
  • table: Table Table object, may absent. Should be present in case of Table service call.

Error object ​

Contains error information.

Properties

  • code: string Error code
  • message: string Detailed error message

Introduction ​

OSRM can be used as a library (libosrm) via C++ instead of using it through the HTTP interface and osrm-routed. This allows for fine-tuning OSRM and has much less overhead. Here is a quick introduction into how to use libosrm in the current version.

Take a look at the example code that lives in the example directory. Here is all you ever wanted to know about libosrm, that is a short description of what the types do and where to find documentation on it:

Important interface objects ​

  • EngineConfig - for initializing an OSRM instance we can configure certain properties and constraints. E.g. the storage config is the base path such as france.osm.osrm from which we derive and load france.osm.osrm.* auxiliary files. This also lets you set constraints such as the maximum number of locations allowed for specific services.

  • OSRM - this is the main Routing Machine type with functions such as Route and Table. You initialize it with a EngineConfig. It does all the heavy lifting for you. Each function takes its own parameters, e.g. the Route function takes RouteParameters, and a out-reference to a JSON result that gets filled. The return value is a Status, indicating error or success.

  • Status - this is a type wrapping Error or Ok for indicating error or success, respectively.

  • TableParameters - this is an example of parameter types the Routing Machine functions expect. In this case Table expects its own parameters as TableParameters. You can see it wrapping two vectors, sources and destinations --- these are indices into your coordinates for the table service to construct a matrix from (empty sources or destinations means: use all of them). If you ask yourself where coordinates come from, you can see TableParameters inheriting from BaseParameters.

  • BaseParameters - this most importantly holds coordinates (and a few other optional properties that you don't need for basic usage); the specific parameter types inherit from BaseParameters to get these member attributes. That means your TableParameters type has coordinates, sources and destinations member attributes (and a few other that we ignore for now).

  • Coordinate - this is a wrapper around a (longitude, latitude) pair. We really don't care about (lon, lat) vs (lat, lon) but we don't want you to accidentally mix them up, so both latitude and longitude are strictly typed wrappers around integers (fixed notation such as 13423240) and floating points (floating notation such as 13.42324).

  • Parameters for other services - here are all other *Parameters you need for other Routing Machine services.

  • JSON - this is a sum type resembling JSON. The Routing Machine service functions take a out-ref to a JSON result and fill it accordingly. It is currently implemented using std::variant. There are two ways to work with this sum type: either provide a visitor that acts on each type on visitation (with std::visit) or use the std::get function in case you're sure about the structure. The JSON structure is written down in the HTTP API.

Example ​

See the example folder in the OSRM repository.

Workflow ​

  • Create an OSRM instance initialized with a EngineConfig
  • Call the service function on the OSRM object providing service specific *Parameters
  • Check the return code and use the JSON result

OSRM ​

The OSRM method is the main constructor for creating an OSRM instance. An OSRM instance requires a .osrm.* dataset(.osrm.* because it contains several files), which is prepared by the OSRM toolchain. You can create such a .osrm.* dataset by running the OSRM binaries we ship in node_modules/osrm/lib/binding_napi_v8/ and default profiles (e.g. for setting speeds and determining road types to route on) in node_modules/osrm/profiles/:

node_modules/osrm/lib/binding_napi_v8/osrm-extract data.osm.pbf -p node_modules/osrm/profiles/car.lua
+node_modules/osrm/lib/binding_napi_v8/osrm-contract data.osrm
+

Consult the osrm-backend documentation for further details.

Once you have a complete network.osrm.* dataset, you can calculate routes in javascript with this object.

javascript
var osrm = new OSRM('network.osrm');

Parameters ​

  • options (Object | String) Options for creating an OSRM object or string to the .osrm file. (optional, default {shared_memory:true})

    • options.algorithm String? The algorithm to use for routing. Can be 'CH', or 'MLD'. Default is 'CH'. Make sure you prepared the dataset with the correct toolchain.
    • options.shared_memory Boolean? Connects to the persistent shared memory datastore. This requires you to run osrm-datastore prior to creating an OSRM object.
    • options.dataset_name String? Connects to the persistent shared memory datastore defined by --dataset_name option when running osrm-datastore. This requires you to run osrm-datastore --dataset_name prior to creating an OSRM object.

tile ​

This generates Mapbox Vector Tiles that can be viewed with a vector-tile capable slippy-map viewer. The tiles contain road geometries and metadata that can be used to examine the routing graph. The tiles are generated directly from the data in-memory, so are in sync with actual routing results, and let you examine which roads are actually routable, and what weights they have applied.

Parameters ​

Examples ​

javascript
var osrm = new OSRM('network.osrm');
+osrm.tile([0, 0, 0], function(err, response) {
+  if (err) throw err;
+  fs.writeFileSync('./tile.vector.pbf', response); // write the buffer to a file
+});

Returns Buffer contains a Protocol Buffer encoded vector tile.

match ​

Map matching matches given GPS points to the road network in the most plausible way. Please note the request might result multiple sub-traces. Large jumps in the timestamps (>60s) or improbable transitions lead to trace splits if a complete matching could not be found. The algorithm might not be able to match all points. Outliers are removed if they can not be matched successfully.

Parameters ​

  • options Object Object literal containing parameters for the match query.

    • options.coordinates Array? The coordinates this request will use, coordinates as [{lon},{lat}] values, in decimal degrees.
    • options.bearings Array? Limits the search to segments with given bearing in degrees towards true north in clockwise direction. Can be null or an array of [{value},{range}] with integer 0 .. 360,integer 0 .. 180.

  • callback Function

Examples ​

javascript
var osrm = new OSRM('network.osrm');
+var options = {
+    coordinates: [[13.393252,52.542648],[13.39478,52.543079],[13.397389,52.542107]],
+    timestamps: [1424684612, 1424684616, 1424684620]

+});

Returns Object containing tracepoints and matchings. tracepoints Array of Ẁaypoint objects representing all points of the trace in order. If the trace point was omitted by map matching because it is an outlier, the entry will be null. Each Waypoint object has the following additional properties, 1) matchings_index: Index to the Route object in matchings the sub-trace was matched to, 2) waypoint_index: Index of the waypoint inside the matched route. 3) alternatives_count: Number of probable alternative matchings for this trace point. A value of zero indicate that this point was matched unambiguously. Split the trace at these points for incremental map matching. matchings is an array of Route objects that assemble the trace. Each Route object has an additional confidence property, which is the confidence of the matching. float value between 0 and 1. 1 is very confident that the matching is correct.

trip ​

The trip plugin solves the Traveling Salesman Problem using a greedy heuristic (farthest-insertion algorithm) for 10 or * more waypoints and uses brute force for less than 10 waypoints. The returned path does not have to be the shortest path, * as TSP is NP-hard it is only an approximation.

Note that all input coordinates have to be connected for the trip service to work. Currently, not all combinations of roundtrip, source and destination are supported. Right now, the following combinations are possible:

roundtripsourcedestinationsupported
truefirstlastyes
truefirstanyyes
trueanylastyes
trueanyanyyes
falsefirstlastyes
falsefirstanyno
falseanylastno
falseanyanyno

Examples ​

javascript
var osrm = new OSRM('network.osrm');
+var options = {
+  coordinates: [
+    [13.36761474609375, 52.51663871100423],
+    [13.374481201171875, 52.506191342034576]

+osrm.trip(options, function(err, response) {
+  if (err) throw err;
+  console.log(response.waypoints); // array of Waypoint objects
+  console.log(response.trips); // array of Route objects
+});

Returns Object containing waypoints and trips. waypoints: an array of Waypoint objects representing all waypoints in input order. Each Waypoint object has the following additional properties, 1) trips_index: index to trips of the sub-trip the point was matched to, and 2) waypoint_index: index of the point in the trip. trips: an array of Route objects that assemble the trace.

Configuration ​

All plugins support a second additional object that is available to configure some NodeJS specific behaviours.

Parameters ​

  • plugin_config Object? Object literal containing parameters for the trip query.

    • plugin_config.format String? The format of the result object to various API calls. Valid options are object (default if options.format is json), which returns a standard Javascript object, as described above, and buffer(default if options.format is flatbuffers), which will return a NodeJS Buffer object, containing a JSON string or Flatbuffers object. The latter has the advantage that it can be immediately serialized to disk/sent over the network, and the generation of the string is performed outside the main NodeJS event loop. This option is ignored by the tile plugin. Also note that options.format set to flatbuffers cannot be used with plugin_config.format set to object. json_buffer is deprecated alias for buffer.

Examples ​

javascript
var osrm = new OSRM('network.osrm');
+var options = {
+  coordinates: [
+    [13.36761474609375, 52.51663871100423],
+    [13.374481201171875, 52.506191342034576]
+  ]
+};
+osrm.route(options, { format: "buffer" }, function(err, response) {
+  if (err) throw err;
+  console.log(response.toString("utf-8"));
+});

OSRM profiles ​

OSRM supports "profiles". Profiles represent routing behavior for different transport modes like car, bike and foot. You can also create profiles for variations like a fastest/shortest car profile or fastest/safest/greenest bicycles profile.

A profile describes whether or not it's possible to route along a particular type of way, whether we can pass a particular node, and how quickly we'll be traveling when we do. This feeds into the way the routing graph is created and thus influences the output routes.

Available profiles ​

Out-of-the-box OSRM comes with profiles for car, bicycle and foot. You can easily modify these or create new ones if you like.

Profiles have a 'lua' extension, and are placed in 'profiles' directory.

When running OSRM preprocessing commands you specify the profile with the --profile (or the shorthand -p) option, for example:

osrm-extract --profile ../profiles/car.lua planet-latest.osm.pbf

Using Multiple Profiles with the Same Input ​

You can extract the same OSM file with different profiles by specifying an output path:

bash
osrm-extract --profile profiles/car.lua planet.osm.pbf --output /data/car
+osrm-extract --profile profiles/bicycle.lua planet.osm.pbf --output /data/bicycle
+osrm-extract --profile profiles/foot.lua planet.osm.pbf --output /data/foot

This avoids the need to create symbolic links to the input file.

Processing flow ​

It's important to understand that profiles are used when preprocessing the OSM data, NOT at query time when routes are computed.

This means that after modifying a profile you will need to extract, contract and reload the data again and to see changes in the routing results. See Processing Flow for more.

Profiles are written in Lua ​

Profiles are not just configuration files. They are scripts written in the Lua scripting language. The reason for this is that OpenStreetMap data is complex, and it's not possible to simply define tag mappings. Lua scripting offers a powerful way to handle all the possible tag combinations found in OpenStreetMap nodes and ways.

Basic structure of profiles ​

A profile will process every node and way in the OSM input data to determine what ways are routable in which direction, at what speed, etc.

A profile will typically:

  • Define api version (required)
  • Require library files (optional)
  • Define setup function (required)
  • Define process functions (some are required)
  • Return functions table (required)

A profile can also define various local functions it needs.

Looking at car.lua as an example, at the top of the file the api version is defined and then required library files are included.

Then follows the setup function, which is called once when the profile is loaded. It returns a big hash table of configurations, specifying things like what speed to use for different way types. The configurations are used later in the various processing functions. Many adjustments can be done just by modifying this configuration table.

The setup function is also where you can do other setup, like loading an elevation data source if you want to consider that when processing ways.

Then come the process_node and process_way functions, which are called for each OSM node and way when extracting OpenStreetMap data with osrm-extract.

The process_turn function processes every possible turn in the network, and sets a penalty depending on the angle and turn of the movement.

Profiles can also define a process_segment function to handle differences in speed along an OSM way, for example to handle elevation. As you can see, this is not currently used in the car profile.

At the end of the file, a table is returned with references to the setup and processing functions the profile has defined.

Understanding speed, weight and rate ​

When computing a route from A to B there can be different measures of what is the best route. That's why there's a need for different profiles.

Because speeds vary on different types of roads, the shortest and the fastest route are typically different. But there are many other possible preferences. For example a user might prefer a bicycle route that follow parks or other green areas, even though both duration and distance are a bit longer.

To handle this, OSRM doesn't simply choose the ways with the highest speed. Instead it uses the concepts of weight and rate. The rate is an abstract measure that you can assign to ways as you like to make some ways preferable to others. Routing will prefer ways with high rate.

The weight of a way is normally computed as length / rate. The weight can be thought of as the resistance or cost when passing the way. Routing will prefer ways with low weight.

You can also set the weight of a way to a fixed value. In this case it's not calculated based on the length or rate, and the rate is ignored.

You should set the speed to your best estimate of the actual speed that will be used on a particular way. This will result in the best estimated travel times.

If you want to prefer certain ways due to other factors than the speed, adjust the rate accordingly. If you adjust the speed, the time estimation will be skewed.

If you set the same rate on all ways, the result will be shortest path routing. If you set rate = speed on all ways, the result will be fastest path routing. If you want to prioritize certain streets, increase the rate on these.

Elements ​

api_version ​

A profile should set api_version at the top of your profile. This is done to ensure that older profiles are still supported when the api changes. If api_version is not defined, 0 will be assumed. The current api version is 4.

Library files ​

The folder profiles/lib/ contains Lua library files for handling many common processing tasks.

FileNotes
way_handlers.luaFunctions for processing way tags
tags.luaFunctions for general parsing of OSM tags
set.luaDefines the Set helper for handling sets of values
sequence.luaDefines the Sequence helper for handling sequences of values
access.luaFunction for finding relevant access tags
destination.luaFunction for finding relevant destination tags
maxspeed.luaFunction for determining maximum speed
guidance.luaFunction for processing guidance attributes

They all return a table of functions when you use require to load them. You can either store this table and reference its functions later, or if you need only a single function you can store that directly.

setup() ​

The setup function is called once when the profile is loaded and must return a table of configurations. It's also where you can do other global setup, like loading data sources that are used during processing.

Note that processing of data is parallelized and several unconnected Lua interpreters will be running at the same time. The setup function will be called once for each. Each Lua interpreter will have its own set of globals.

The following global properties can be set under properties in the hash you return in the setup function:

process_node(profile, node, result, relations) ​

Process an OSM node to determine whether this node is an obstacle, if it can be passed at all and whether passing it incurs a delay.

ArgumentDescription
profileThe configuration table you returned in setup.
nodeThe input node to process (read-only).
resultThe output that you will modify.
relationsStorage of relations to access relations, where node is a member.

The following attributes can be set on result: (Note: for new code use the obstacle_map.

AttributeTypeNotes
barrierBooleanIs it an impassable barrier?
traffic_lightsBooleanIs it a traffic light (incurs delay in process_turn)?

Obstacle ​

A user type that represents an obstacle on the road or a place where you can turn around.

This may be a completely impassable obstacle like a barrier, a temporary obstacle like a traffic light or a stop sign, or an obstacle that just slows you down like a traffic_calming. The obstacle may be present in both directions or in one direction only.

This also represents a good turning point like a mini_roundabout, turning_loop, or turning_circle.

An object of this type is immutable once constructed.

lua
local obs = Obstacle.new(
+  obstacle_type.traffic_signals,
+  obstacle_direction.forward,
+  2.5,
+  0
+)
+assert(obs.duration == 2.5)
MemberModeTypeNotes

weightread-onlyfloatThe weight

obstacle_type ​

An enum with the following keys:

Keys
none
barrier
traffic_signals
stop
give_way
crossing
traffic_calming
mini_roundabout
turning_loop
turning_circle
gate

obstacle_direction ​

An enum with the following keys:

Keys
none
forward
backward
both

obstacle_map ​

A global user type. It stores obstacles.

The canonical workflow is: to store obstacles in process_node() and retrieve them in process_turn().

Note: In the course of processing, between the process_node() stage and the process_turn() stage, the extractor switches from using OSM nodes to using internal nodes. Both types have different ids. You can only store OSM nodes and only retrieve internal nodes. This implies that, in process_node(), you cannot retrieve an obstacle you have just stored.

obstacle_map:add(node, obstacle) ​

Call this function inside process_node() to register an obstacle on a node. You can register as many different obstacles as you wish on any given node. It is your responsibility to register the same obstacle only once.

In a following step -- likely in process_turn() -- you can retrieve all obstacles registered at any given node. This function works with OSM nodes.

ArgumentTypeNotes
nodeOSMNodeThe same node as passed to process_node.
obstacleObstacleThe obstacle

Usage example:

lua
function process_node(profile, node, result, relations)
+  ...
+  obstacle_map:add(node,
+    Obstacle.new(
+      obstacle_type.traffic_signal,
+      obstacle_direction.forward,
+      2, 0))
+end

obstacle_map:any(from, to, type) ​

Return true if there are any obstacles at node to when coming from node from and having the type type.

You will likely call this function inside process_turn(). Note that this works only with internal nodes, not with OSM nodes.

lua
bool obstacle_map:any(to)
+bool obstacle_map:any(from, to)
+bool obstacle_map:any(from, to, type)
ArgumentTypeNotes
fromNodeThe leading node. Optional.
toNodeThe node with the obstacle.
typeobstacle_typeThe obstacle type. Defaults to all types. May be a bitwise-or combination of types.
returnsboolTrue if there are any obstacles satisfiying the given criteria.

Usage examples:

lua
function process_turn(profile, turn)
+  if obstacle_map:any(turn.via) then
+    ...
+  end
+  if obstacle_map:any(turn.from, turn.via, obstacle_type.traffic_signal) then
+    turn.duration = turn.duration + 2
+  end
+end

obstacle_map:get(from, to, type) ​

This function retrieves all registered obstacles at node to when coming from the node from and having the type type.

You will likely call this function inside process_turn(). Note that this works only with internal nodes, not with OSM nodes.

lua
obstacle_map:get(to)
+obstacle_map:get(from, to)
+obstacle_map:get(from, to, type)
ArgumentTypeNotes
fromNodeThe leading node. Optional.
toNodeThe node with the obstacle.
typeobstacle_typeThe obstacle type. Defaults to all types. May be a bitwise-or combination of types.
returnstableA table of Obstacles.

Usage examples:

lua
function process_turn(profile, turn)
+  for _, obs in pairs(obstacle_map:get(turn.via)) do
+    if obs.type == obstacle_type.barrier then
+      turn.duration = turn.duration + obs.duration
+    end
+  end
+  for _, obs in pairs(obstacle_map:get(
+      turn.from, turn.via, obstacle_type.traffic_signal)) do
+    turn.duration = turn.duration + obs.duration
+  end
+end

process_way(profile, way, result, relations) ​

Given an OpenStreetMap way, the process_way function will either return nothing (meaning we are not going to route over this way at all), or it will set up a result hash.

ArgumentDescription
profileThe configuration table you returned in setup.
wayThe input way to process (read-only).
resultThe output that you will modify.
relationsStorage of relations to access relations, where way is a member.

Importantly it will set result.forward_mode and result.backward_mode to indicate the travel mode in each direction, as well as set result.forward_speed and result.backward_speed to integer values representing the speed for traversing the way.

It will also set a number of other attributes on result.

Using the power of the scripting language you wouldn't typically see something as simple as a result.forward_speed = 20 line within the process_way function. Instead process_way will examine the tag set on the way, process this information in various ways, calling other local functions and referencing the configuration in profile, etc., before arriving at the result.

The following attributes can be set on the result in process_way:

AttributeTypeNotes
forward_speedFloatSpeed on this way in km/h. Mandatory.
backward_speedFloat""
forward_rateFloatRouting weight, expressed as meters/weight (e.g. for a fastest-route weighting, you would want this to be meters/second, so set it to forward_speed/3.6)
backward_rateFloat""
forward_modeEnumMode of travel (e.g. car, ferry). Mandatory. Defined in include/extractor/travel_mode.hpp.
backward_modeEnum""
forward_classesTableMark this way as being of a specific class, e.g. result.classes["toll"] = true. This will be exposed in the API as classes on each RouteStep.
backward_classesTable""
durationFloatAlternative setter for duration of the whole way in both directions
weightFloatAlternative setter for weight of the whole way in both directions
turn_lanes_forwardStringDirections for individual lanes (normalized OSM turn:lanes value)
turn_lanes_backwardString""
forward_restrictedBooleanIs this a restricted access road? (e.g. private, or deliveries only; used to enable high turn penalty, so that way is only chosen for start/end of route)
backward_restrictedBoolean""
is_startpointBooleanCan a journey start on this way? (e.g. ferry; if false, prevents snapping the start point to this way)
roundaboutBooleanIs this part of a roundabout?
circularBooleanIs this part of a non-roundabout circular junction?

road_classification.link_classBooleanGuidance: way is a slip/link road
road_classification.road_priority_classEnumGuidance: order in priority list. Defined in include/extractor/road_classification.hpp
road_classification.may_be_ignoredBooleanGuidance: way is non-highway
road_classification.num_lanesUnsignedGuidance: total number of lanes in way

Way names ​

The WayHandlers.names function in way_handlers.lua handles extraction of way names for routing instructions. It processes the following OSM tags:

TagNotes
namePrimary name of the way
name:pronunciationPronunciation hint for text-to-speech
refRoad reference number (e.g., "A1", "I-95")
junction:refExit or junction reference number

For unnamed sidewalks and sidepaths (where highway=footway, highway=cycleway, or highway=path), the function also supports fallback name tags when the way is marked as a sidepath:

TagNotes
is_sidepath:of:nameName of the street the sidepath follows (checked first)
street:nameAlternative tag for the associated street name

The fallback is only applied when the way has one of these sidepath markers:

  • footway=sidewalk
  • cycleway=sidepath
  • is_sidepath=yes

This allows routing instructions to show street names for separately mapped sidewalks, e.g., "Turn right onto Main Street" instead of just "Turn right".

process_segment(profile, segment) ​

The process_segment function is called for every segment of OSM ways. A segment is a straight line between two OSM nodes.

An OpenStreetMap way cannot have different tags on different parts of a way. Instead you would split the way into several smaller ways. However, many ways are long. For example, many ways pass over hills without any change in tags.

Processing each segment of an OSM way makes it possible to have different speeds on different parts of a way based on external data like data about elevation, pollution, noise or scenic value and adjust weight and duration of the segment accordingly.

In the process_segment function you don't have access to OSM tags. Instead you use the geographical location of the start and end point of the way to look up information from another data source, like elevation data. See rasterbot.lua for an example.

The following attributes can be read and set on the result in process_segment:

AttributeRead/write?TypeNotes
source.lonReadFloatCo-ordinates of segment start
source.latReadFloat""
target.lonReadFloatCo-ordinates of segment end
target.latReadFloat""
distanceReadFloatLength of segment
weightRead/writeFloatRouting weight for this segment
durationRead/writeFloatDuration for this segment

process_turn(profile, turn) ​

The process_turn function is called for every possible turn in the network. Based on the angle and type of turn you assign the weight and duration of the movement.

The following attributes can be read and set on the result in process_turn:

AttributeRead/write?TypeNotes

Use these node IDs to retrieve obstacles. See: obstacle_map:get.

source_road, target_road, roads_on_the_right, and roads_on_the_left ​

The information of source_road, target_road, roads_on_the_right, and roads_on_the_left that can be read are as follows:

AttributeRead/write?TypeNotes
is_restrictedReadBooleanIs it a restricted access road? (See definition in process_way)

The order of the roads in roads_on_the_right and roads_on_the_left are counter clockwise. If the turn is a u turn, all other connected roads will be in roads_on_the_right.

Example

           c   e
+           |  /
+           | /
+    a ---- x ---- b
+          /|
+         / |
+        f  d

When turning from a to b via x,

  • roads_on_the_right[1] is the road xf
  • roads_on_the_right[2] is the road xd
  • roads_on_the_left[1] is the road xe
  • roads_on_the_left[2] is the road xc

Note that indices of arrays in Lua are 1-based.

highway_turn_classification and access_turn_classification ​

When setting appropriate turn weights and duration, information about the highway and access tags of roads that are involved in the turn are necessary. The Lua turn function process_turn does not have access to the original OSM tags anymore. However, highway_turn_classification and access_turn_classification can be set during setup. The classification set during setup can be later used in process_turn.

Example

In the following example we use highway_turn_classification to set the turn weight to 10 if the turn is on a highway and to 5 if the turn is on a primary.

function setup()
+  return {
+    highway_turn_classification = {
+      ['motorway'] = 2,
+      ['primary'] = 1
+    }
+  }
+end
+
+function process_turn(profile, turn) {
+  if turn.source_highway_turn_classification == 2 and turn.target_highway_turn_classification == 2 then
+    turn.weight = 10
+  end
+  if turn.source_highway_turn_classification == 1 and turn.target_highway_turn_classification == 1 then
+    turn.weight = 5
+  end
+}

Guidance ​

The guidance parameters in profiles are currently a work in progress. They can and will change. Please be aware of this when using guidance configuration possibilities.

Guidance uses road classes to decide on when/if to emit specific instructions and to discover which road is obvious when following a route. Classification uses three flags and a priority-category. The flags indicate whether a road is a motorway (required for on/off ramps), a link type (the ramps itself, if also a motorway) and whether a road may be omitted in considerations (is considered purely for connectivity). The priority-category influences the decision which road is considered the obvious choice and which roads can be seen as fork. Forks can be emitted between roads of similar priority category only. Obvious choices follow a major priority road, if the priority difference is large.

Using raster data ​

OSRM has built-in support for loading an interpolating raster data in ASCII format. This can be used e.g. for factoring in elevation when computing routes.

Use raster:load() in your setup function to load data and store the source in your configuration hash:

lua
function setup()
+  return {
+    raster_source = raster:load(
+      "rastersource.asc",  -- file to load
+      0,    -- longitude min
+      0.1,  -- longitude max
+      0,    -- latitude min
+      0.1,  -- latitude max
+      5,    -- number of rows
+      4     -- number of columns
+    )
+  }
+end

The input data must be an ASCII file with rows of integers, e.g.:

0  0  0   0
+0  0  0   250
+0  0  250 500
+0  0  0   250
+0  0  0   0

In your segment_function you can then access the raster source and use raster:query() to query to find the nearest data point, or raster:interpolate() to interpolate a value based on nearby data points.

You must check whether the result is valid before using it.

Example:

lua
function process_segment (profile, segment)
+  local sourceData = raster:query(profile.raster_source, segment.source.lon, segment.source.lat)
+  local targetData = raster:query(profile.raster_source, segment.target.lon, segment.target.lat)
+
+  local invalid = sourceData.invalid_data()
+  if sourceData.datum ~= invalid and targetData.datum ~= invalid then
+      -- use values to adjust weight and duration
+    [...]
+end

See rasterbot.lua and rasterbotinterp.lua for examples.

params = osrm.TileParameters(x=17059, y=11948, z=15)
+result = engine.Tile(params)  # returns bytes

TileParameters ​

  • x int - Tile x coordinate.
  • y int - Tile y coordinate.
  • z int - Tile zoom level.

BaseParameters ​

Shared parameters inherited by Nearest, Table, Route, Match, and Trip.

  • coordinates list[tuple[float, float]] - List of (longitude, latitude) pairs.
  • hints list[str | None] - Base64-encoded hints from previous requests.
  • radiuses list[float | None] - Search radius per coordinate in meters. None for unlimited.
  • bearings list[tuple[int, int] | None] - (bearing, range) pairs in degrees. None for unrestricted.
  • approaches list[str | None] - "curb", "unrestricted", or None.
  • generate_hints bool - Include hints in response. Default: True.
  • exclude list[str] - Road classes to avoid (e.g. ["motorway"]).
  • snapping str - "default" or "any". Default: "default".

Types ​

Coordinate ​

python
coord = osrm.Coordinate((7.41337, 43.72956))
+print(coord.lon, coord.lat)

Bearing ​

python
bearing = osrm.Bearing((200, 180))
+print(bearing.bearing, bearing.range)

Object / Array ​

Service results are returned as Object (dict-like) and Array (list-like) wrappers around OSRM's internal JSON types. They support [], len(), in, and iteration.

python
result = engine.Route(params)
+for route in result["routes"]:
+    print(route["distance"], route["duration"])

CLI ​

The package also installs OSRM command-line tools, accessible via python -m osrm:

bash
python -m osrm extract data.osm.pbf -p profiles/car.lua
+python -m osrm contract data.osrm
+python -m osrm partition data.osrm
+python -m osrm customize data.osrm
+python -m osrm datastore data.osrm
+python -m osrm routed data.osrm

Python Bindings Development Guide ​

Installing for production ​

Pre-built wheels are published to PyPI for Linux (x86_64), macOS (x86_64), and Windows (amd64). They use the CPython 3.12 stable ABI (cp312-abi3) and therefore install on Python 3.12+:

bash
pip install osrm-bindings

The package itself supports Python 3.10+ when built from source — needed for 3.10/3.11, aarch64 Linux, arm64 macOS, or any platform without a pre-built wheel:

bash
pip install osrm-bindings --no-binary osrm-bindings

Source builds compile the full OSRM C++ library — this takes a long time. See platform-specific notes for prerequisites.

Installing for development ​

Clone the repo and install in editable mode with dev dependencies:

bash
git clone https://github.com/Project-OSRM/osrm-backend
+cd osrm-backend
+pip install -e ".[dev]"

Install pre-commit hooks:

bash
pre-commit install

Platform-specific build requirements ​

Linux ​

CI wheel builds run inside a custom manylinux image (nilsnolde/manylinux, branch osrm_python) that ships vcpkg pre-bootstrapped at the SHA pinned in vcpkg-configuration.json, plus a pre-warmed vcpkg binary cache compiled against this repo's vcpkg.json. The wheel build's own vcpkg install hits that cache instead of recompiling boost/tbb/etc. from source.

The image needs rebuilding when this repo's vcpkg.json, the baseline SHA in vcpkg-configuration.json, or any file under vcpkg-overlay-ports/ changes — otherwise the wheel build either misses the cache (slow) or fails on a missing port. The manylinux repo's Build workflow takes an osrmRef input for that purpose; see its README.

For local source builds outside the manylinux image, install vcpkg yourself, point CMake at its toolchain, and use the release-only triplet to match the cache:

bash
git clone https://github.com/microsoft/vcpkg
+./vcpkg/bootstrap-vcpkg.sh
+export VCPKG_ROOT=$PWD/vcpkg
+export CMAKE_ARGS="-DCMAKE_TOOLCHAIN_FILE=$VCPKG_ROOT/scripts/buildsystems/vcpkg.cmake -DVCPKG_TARGET_TRIPLET=x64-linux-release"

macOS ​

Install OSRM's C++ dependencies via Homebrew (the same set the cibuildwheel macOS before-all uses; all ship CMake config files so the find_package(... CONFIG REQUIRED) calls in CMakeLists.txt resolve without a toolchain file):

bash
brew install lua tbb boost@1.90 fmt rapidjson sol2 flatbuffers \\
+             protozero libosmium
+brew link boost@1.90

Windows ​

Windows uses vcpkg in manifest mode for OSRM's C++ dependencies. Clone and bootstrap it, then export VCPKG_ROOT:

powershell
git clone https://github.com/microsoft/vcpkg
+.\\vcpkg\\bootstrap-vcpkg.bat
+$env:VCPKG_ROOT = "$PWD\\vcpkg"

Pass the toolchain to CMake at build time via CMAKE_ARGS (see below).

Building locally ​

A standard pip install -e . works, but by default pip uses PEP 517 isolated builds — each invocation creates a temporary directory, compiles everything, then discards it. This means OSRM is recompiled from scratch every time.

Use --no-build-isolation to make scikit-build-core reuse the persistent build directory (build/{wheel_tag}/) across runs:

bash
# Linux / macOS
+pip install -e . --no-build-isolation
+
+# Windows (PowerShell) — VCPKG_ROOT must be set, see Platform-specific
+# build requirements
+$env:CMAKE_ARGS = "-DCMAKE_TOOLCHAIN_FILE=$env:VCPKG_ROOT\\scripts\\buildsystems\\vcpkg.cmake -DVCPKG_TARGET_TRIPLET=x64-windows-static-md"
+pip install -e . --no-build-isolation

The first run is slow (full OSRM compile). Subsequent runs only recompile changed binding files.

Keep config flags identical across runs

scikit-build-core hashes its configuration to detect changes. If the flags differ between runs, it wipes the build directory and starts from scratch.

Generator mismatch

CMake records the generator in CMakeCache.txt. If you ever see Does not match the generator used previously, delete the build directory and rebuild from scratch:

powershell
Remove-Item -Recurse -Force build/cp312-abi3-win_amd64

Building a wheel ​

After the editable install has compiled everything, produce a wheel without recompiling:

bash
# Linux / macOS
+pip wheel . --no-build-isolation -w dist
+
+# Windows (PowerShell) — uses the same CMAKE_ARGS as the editable install above
+pip wheel . --no-build-isolation -w dist

CMake finds the existing artifacts in the build directory and skips recompilation. The wheel lands in dist/.

Wheel repair ​

Locally built wheels link against system shared libraries and are tagged as linux_x86_64 (not manylinux). To make them portable or to inspect their dependencies, use the platform-specific repair tools:

Linux — auditwheel:

bash
pip install auditwheel
+auditwheel show dist/*.whl          # inspect shared library dependencies
+auditwheel repair -w dist dist/*.whl # bundle libs and retag as manylinux

macOS — delocate:

bash
pip install delocate
+delocate-listdeps dist/*.whl        # inspect dependencies
+delocate-wheel -w dist dist/*.whl   # bundle dylibs

Windows — delvewheel:

bash
pip install delvewheel
+delvewheel show dist/*.whl          # inspect dependencies
+delvewheel repair -w dist dist/*.whl

On Windows, vcpkg's shared DLLs (tbb12.dll, hwloc.dll — TBB is shared even under the static-md triplet) live in build\\<wheel-tag>\\vcpkg_installed\\x64-windows-static-md\\bin\\. Pass that to delvewheel via --add-path so it can resolve and bundle them:

powershell
delvewheel repair --analyze-existing-exes \`
+    --add-path build\\cp312-abi3-win_amd64\\vcpkg_installed\\x64-windows-static-md\\bin \`
+    --add-dll hwloc.dll --no-mangle tbb12.dll --no-mangle hwloc.dll \`
+    -w dist dist\\*.whl

TIP

cibuildwheel runs wheel repair automatically in CI. You only need these commands when building wheels locally for distribution.

Compiler cache ​

On Linux and macOS, ccache is used automatically (pre-installed in the manylinux image; installed via Homebrew for macOS CI).

On Windows, scikit-build-core defaults to the Visual Studio generator, which does not support CMAKE_CXX_COMPILER_LAUNCHER. The build dir reuse from --no-build-isolation is the main speed optimisation for local Windows development.

Running tests ​

Build the test data (requires the package to be installed so the osrm executables are available):

bash
# Linux / macOS
+cd test/data && make
+
+# Windows
+cd test\\data && windows-build-test-data.bat

Load the shared memory datastore:

bash
python -m osrm datastore test/data/ch/monaco

Run the test suite:

bash
pytest test/python/

Running cibuildwheel locally ​

cibuildwheel builds wheels inside isolated environments that closely match CI. Install it with:

bash
pip install cibuildwheel

Build for the current platform:

bash
cibuildwheel --platform linux    # requires Docker on non-Linux hosts
+cibuildwheel --platform macos
+cibuildwheel --platform windows

Wheels land in wheelhouse/.

Windows note: the toolchain wiring (CMAKE_TOOLCHAIN_FILE, VCPKG_TARGET_TRIPLET) lives in [tool.cibuildwheel.windows].environment in pyproject.toml, where $VCPKG_ROOT is expanded at build time from the host environment. Make sure VCPKG_ROOT is set in your shell before invoking cibuildwheel.

Linux note: the wheel build inside the manylinux container reads VCPKG_ROOT and VCPKG_DEFAULT_BINARY_CACHE from the image's ENV, so no toolchain forwarding is needed from the host. If you override CIBW_ENVIRONMENT_LINUX to mount a host ccache, remember it replaces (not merges with) [tool.cibuildwheel.linux].environment in pyproject.toml — re-include LD_LIBRARY_PATH and the CMAKE_ARGS line verbatim:

bash
CIBW_CONTAINER_ENGINE="docker; create_args: --volume /tmp/ccache:/ccache" \\
+CIBW_ENVIRONMENT_LINUX='LD_LIBRARY_PATH=/usr/local/lib64:\${LD_LIBRARY_PATH} CCACHE_DIR=/ccache CMAKE_ARGS="-DCMAKE_TOOLCHAIN_FILE=$VCPKG_ROOT/scripts/buildsystems/vcpkg.cmake -DVCPKG_TARGET_TRIPLET=x64-linux-release"' \\
+cibuildwheel --platform linux

Type stubs ​

src/python/osrm/osrm_ext.pyi is auto-generated by nanobind_add_stub() at build time and committed to the repository so documentation tools can work without compiling the extension.

After changing C++ bindings, rebuild and commit the updated stub:

bash
pip install -e . --no-build-isolation   # regenerates the .pyi
+git add src/python/osrm/osrm_ext.pyi

To regenerate manually without a full rebuild:

bash
pip install nanobind ruff
+python -m nanobind.stubgen -m osrm.osrm_ext -o src/python/osrm/osrm_ext.pyi
+ruff format src/python/osrm/osrm_ext.pyi

Releasing ​

Releases are driven by the monthly release workflow (.github/workflows/release-monthly.yml), not by pushing a tag by hand. The workflow bumps the version, creates the tag, drives CI, downloads the built wheels, and publishes to both PyPI and npm in one shot.

Scheduled monthly release ​

A cron on the 1st of each month at 08:00 UTC runs the workflow against master:

  1. Compute the next version as (YYYY-2000).M.patchlevel (e.g. 26.4.0).
  2. Bump package.json + package-lock.json, commit, create annotated tag v<version>, push branch and tag.
  3. Dispatch osrm-backend.yml on the tag. That run builds wheels + sdist via cibuildwheel and uploads them as wheels-* artifacts.
  4. Wait for the dispatched CI run to finish with conclusion success.
  5. Run the publish job: download every wheels-* artifact into dist/, publish to PyPI via trusted publisher (OIDC), then npm publish.

If PyPI fails, the npm publish still runs (the npm steps have if: \${{ !cancelled() }}), and the overall job is marked failed so the PyPI problem stays visible.

Manual release ​

Trigger the workflow from the Actions UI or gh workflow run release-monthly.yml with optional inputs:

  • version_override — set the version explicitly (e.g. 26.4.1) instead of using the (YYYY-2000).M.patchlevel calculation.
  • branch — release from a branch other than master.

Verification ​

After the run finishes, check:

Version mechanics ​

pyproject.toml uses setuptools-scm with local_scheme = "no-local-version". On a tag checkout (e.g. v26.4.0), the Python version resolves cleanly to 26.4.0, matching the package.json version that release-monthly.yml committed when creating the tag.

Releasing a new OSRM version ​

We use a unified semver versioning scheme for monthly releases: (YYYY-2000).M.patchlevel

  • Format: X.M.patchlevel where X = year - 2000, M = month (1-12, no leading zeros)
  • Example: 26.4.0 represents April 2026, first release
  • Git tags: Prefixed with v (e.g., v26.4.0)
  • npm packages: Unprefixed semver (e.g., 26.4.0)

Version History ​

Previous scheme (ended 2025): Traditional semantic versioning (v6.0, v6.0.1, v6.0.2, etc.)

  • Last release: v6.0.0 in December 2025
  • Manual release process

New scheme (started 2026): Monthly date-based versioning with automated releases

  • First release: v26.1.0 (January 2026)
  • Automatic monthly releases on the 1st of each month at 08:00 UTC
  • Year offset: 2026 → 26, 2027 → 27, etc.
  • Month: 1-12 (no leading zeros), patch: 0-N per month

Versioning Scheme ​

Format ​

Git tags: vX.M.patchlevel where X = year - 2000, M = 1-12

  • X: Year offset (26 = 2026, 27 = 2027, etc.)
  • M: Month (1-12, no leading zeros)
  • patchlevel: Incremental counter starting at 0 per month (0, 1, 2, ...)

npm packages: X.M.patchlevel (same as git tag without the v prefix)

Examples ​

Git tags and npm versions for the same release:

  • April 2026, 1st release: Git tag v26.4.0, npm 26.4.0
  • April 2026, 2nd release: Git tag v26.4.1, npm 26.4.1
  • May 2026, 1st release: Git tag v26.5.0, npm 26.5.0
  • January 2027, 1st release: Git tag v27.1.0, npm 27.1.0

Release Compatibility Guarantees ​

Patch version change (new patchlevel in same month) ​

  • No change of query parameters or response formats
  • Compatible HTTP API
  • Compatible C++ library API
  • Compatible node-osrm API
  • Compatible OSRM datasets

Month change (new YYYY-MM) ​

  • May introduce forward-compatible changes: query parameters and response properties may be added in responses, but existing properties may not be changed or removed
  • Forward-compatible HTTP API
  • Forward-compatible C++ library API
  • Forward-compatible node-osrm API
  • No compatibility between OSRM datasets (needs new processing)

Conventional Commits ​

Pull request titles must follow Conventional Commits format with types: feat, fix, docs, style, refactor, perf, test, ci, chore, build. This is validated in CI and helps organize the commit history.

Breaking changes should be indicated with the ! suffix in the PR title (e.g., feat!: remove deprecated API) so they are called out in release notes.

Release Management ​

  • The master branch is for development and should always be green
  • Automated monthly releases occur on the 1st of each month at 08:00 UTC
  • All changes in master will be automatically released monthly
  • No release candidates are used; the master branch is the quality gate
  • Patch versions within the same month can be released manually at any time

Automated Release Process ​

Releases are created automatically every month on a scheduled basis:

  1. A GitHub Actions workflow runs on the 1st of each month at 08:00 UTC
  2. Version is calculated as (YYYY-2000).M.patchlevel with M = 1-12 (no leading zeros)
  3. package.json and package-lock.json versions are updated
  4. A git tag is created and pushed (e.g., v26.4.0)
  5. A GitHub Release is published with auto-generated release notes
  6. The package is published to npm (format: 26.4.0 without v prefix)

Manual Release Trigger ​

You can also trigger a release manually on any branch:

  1. Go to Actions → Monthly Release workflow
  2. Click Run workflow
  3. Select your branch (defaults to master)
  4. Optionally override the version (format: X.M.patchlevel with M = 1-12, e.g., 26.4.0)
  5. Click Run workflow

This is useful for:

  • Out-of-schedule patch releases within the same month
  • Emergency releases from other branches
  • Backports to older versions

Release Checklist ​

When releasing (automated or manual):

  1. ✅ All GitHub Actions CI checks pass
  2. ✅ The target branch is in a releasable state
  3. ✅ For manual releases: verify the version format is correct (X.M.patchlevel with month 1-12, e.g., 26.4.0)
  4. ✅ The release is created automatically with:
    • Git tag
    • GitHub Release (with auto-generated release notes)
    • npm publication

After Release ​

No additional manual steps are required. The automated workflow handles:

  • Version bumping in package.json
  • Git commit and tag creation
  • GitHub Release publishing
  • npm package publication

For non-automated releases, monitor:

  • GitHub Actions to verify the release completed successfully
  • npm registry to confirm the new version is published

Environment Variables ​

SHM_LOCK_DIR ​

If the SHM_LOCK_DIR environment variable is set, OSRM will use it as the directory for shared memory lock files instead of the system temporary directory. This is useful in containerized environments (Docker/Kubernetes) where the lock file directory should persist across container restarts when loading from shared memory.

SIGNAL_PARENT_WHEN_READY ​

If the SIGNAL_PARENT_WHEN_READY environment variable is set osrm-routed will send the USR1 signal to its parent when it will be running and waiting for requests. This could be used to upgrade osrm-routed to a new binary on the fly without any service downtime - no incoming requests will be lost.

DISABLE_ACCESS_LOGGING ​

If the DISABLE_ACCESS_LOGGING environment variable is set osrm-routed will not log any http requests to standard output. This can be useful in high traffic setup.

Testsuite ​

OSRM comes with a testsuite containing both unit-tests using the Boost library and cucumber.js for scenario driven testing.

Unit Tests ​

For a general introduction on Boost.Test have a look at its docs.

Separate Test Binaries ​

Unit tests should be registered according to the sub-project they're in. If you want to write tests for utility functions, add them to the utility test binary. See CMakeLists.txt in the unit test directory for how to register new unit tests.

Using Boost.Test Primitives ​

There is a difference between only reporting a failed condition and aborting the test right at a failed condition. Have a look at BOOST_CHECK vs BOOST_REQUIRE. Instead of manually checking e.g. for equality, less than, if a function throws etc. use their corresponding Boost.Test primitives.

If you use BOOST_CHECK_EQUAL you have to implement operator<< for your type so that Boost.Test can print mismatches. If you do not want to do this, define BOOST_TEST_DONT_PRINT_LOG_VALUE (and undef it after the check call) or sidestep it with BOOST_CHECK(fst == snd);.

Test Fixture ​

If you need to test features on a real dataset (think about this twice: prefer cucumber and dataset-independent tests for their reproducibility and minimality), there is a fixed dataset in test/data. This dataset is a small extract and may not even contain all tags or edge cases. Furthermore this dataset is not in sync with what you see in up-to-date OSM maps or on the demo server. See the library tests for how to add new dataset dependent tests.

To prepare the test data simply cd test/data/ and then run make.

Running Tests ​

To build the unit tests:

cd build
+cmake ..
+make tests

You should see the compiled binaries in build/unit_tests, you can then run each suite individually:

./engine-tests

Cucumber ​

For a general introduction on cucumber in our testsuite, have a look at the wiki.

This documentation aims to supply a guideline on how to write cucumber tests that test new features introduced into osrm.

Test the feature ​

It is often tempting to reduce the test to a path and accompanying instructions. Instructions can and will change over the course of improving guidance.

Instructions should only be used when writing a feature located in features/guidance. All other features should avoid using instructions at all.

Write Tests to Scale ​

OSRM is a navigation engine. Tests should always consider this context.

An important implication is the grid size. If tests use a very small grid size, you run into the chance of instructions being omitted. For example:

Background:
+    Given the profile "car"
+    Given a grid size of 10 meters
+
+Scenario: Testbot - Straight Road
+    Given the node map
+        """
+        a b c d
+        """
+
+    And the ways
+        | nodes | highway |
+        | ab    | primary |
+        | bc    | primary |
+        | cd    | primary |
+
+    When I route I should get
+        | from | to | route       |
+        | a    | d  | ab,bc,cd,cd |

In a navigation engine, the instructions

  • depart east on ab
  • in 10 meters the road name changes to bc
  • in 10 meters the road name changes to cd
  • you arrived at cd

would be impossible to announce and not helpful at all. Since no actual choices exist, the route you get could result in ab,cd and simply say depart and arrive.

To prevent such surprises, always consider the availability of other roads and use grid sizes/road lengths that correspond to actually reasonable scenarios in a road network.

Use names ​

If you specify many nodes in close succession to present a specific road geometry, consider using name to indicate to OSRM that the segment is a single road.

Guidance guarantees only essential maneuvers. You will always see depart and arrive as well as all turns that are not obvious.

Test all directions ​

Modelling a road as roundabout has an implied oneway tag associated with it. In the following case, we can route from a to d but not from d to a. To discover those errors, make sure to check for all allowed directions.

Prevent Randomness ​

Some features in OSRM can result in strange experiences during testcases. To prevent some of these issues, follow the guidelines below.

Use Waypoints ​

Using grid nodes as waypoints offers the chance of unwanted side effects. OSRM converts the grid into a so called edge-based graph.

Scenario: Testbot - Intersection
+    Given the node map
+        """
+          e
+        b a d
+          c
+        """
+
+    And the ways
+        | nodes | highway | oneway |
+        | ab    | primary | yes    |
+        | ac    | primary | yes    |
+        | ad    | primary | yes    |
+        | ae    | primary | yes    |

Selecting a as a waypoint results in four possible starting locations. Which one of the routes a,b, a,c, a,d, or a,e is found is pure chance and depends on the order in the static r-tree.

To guarantee discovery, use:

Scenario: Testbot - Intersection
+    Given the node map
+        """
+            e
+            4
+        b 1 a 3 d
+            2
+            c
+        """
+
+    And the ways
+        | nodes | highway | oneway |
+        | ab    | primary | yes    |
+        | ac    | primary | yes    |
+        | ad    | primary | yes    |
+        | ae    | primary | yes    |

And use 1,2,3, and 4 as starting waypoints. The routes 1,b, 2,c, 3,d, and 4,e can all be discovered.

Allow For Small Offsets ​

Whenever you are independent of the start location (see use waypoints), the waypoint chosen as start/end location can still influence distances/durations.

If you are testing for a duration metric, allow for a tiny offset to ensure a passing test in the presence of rounding/snapping issues.

Don't Rely on Alternatives ​

Alternative route discovery is a random feature in itself. The discovery of routes depends on the contraction order of roads and cannot be assumed successful, ever.

Understanding Turn Restrictions ​

Adding turn restrictions requires the restriction to follow a very specific format.

We specify them in a table with the header | type | way:from | way:to | node:via | restriction |. It is important that turn restrictions require micro segmentation.

Consider the following scenario:

Given the node map:
+    """
+          e
+          |
+    a - - b - - c
+          |
+          d
+    """
+
+And the ways
+    | nodes | oneway |
+    | abc   | yes    |
+    | ebd   | yes    |
+
+And the relations
+    | type        | way:from | way:to | node:via | restriction   |
+    | restriction | abc      | ebd    | b        | no_right_turn |

The setting looks perfectly fine at first glance. However, it is not well defined. The forbidden right turn could be either a superfluous addition, forbidding the turn cb to be, or actually refer to the turn ab to bd to say that a turn is forbidden here.

To model turn-restrictions correctly and uniquely, we need to split segments that contribute to the restriction into the smallest possible parts. E.g. the above scenario could correctly be expressed as:

Given the node map:
+    """
+          e
+          |
+    a - - b - - c
+          |
+          d
+    """
+
+And the ways
+    | nodes | oneway | name |
+    | ab    | yes    | abc  |
+    | bc    | yes    | abc  |
+    | eb    | yes    | ebd  |
+    | bd    | yes    | ebd  |
+
+And the relations
+    | type        | way:from | way:to | node:via | restriction   |
+    | restriction | ab       | bd     | b        | no_right_turn |

Unless this format is used, OSRM will omit the (then ambiguous) turn restrictions and ignore them.

My Guidance Tests are Failing - Understanding what you can change ​

If you change some stuff in guidance, you will easily see tests change their result. E.g. if you change the angles for which we report right, then obviously some tests might not report a direction modifier named right anymore.

This small section will try to guide you in making the correct decisions for changing the behaviour of tests.

The difficulty in guidance tests is that not all items can be translated 1:1 from the ascii art into turn-angles.

The turn-angle calculation tries to find turn angles that would represent perceived turn angles, not the exact angle at the connection.

This is necessary, since connections in OSM are always bound by the paradigm that the way is supposed to be in the middle of the actual road. For broad streets, you will see stronger angles than the actual turns.

Don't change the test, change the expected behaviour ​

If we have a test that looks like this:

Given a grid size of 5 m
+Given the node map
+"""
+a - b - - - - - - c
+     \\  
+      d - - - - - e
+"""
+
+When I route I should get
+ | waypoints | route       | turns                          |
+ | a,e       | abc,bde,bde | depart,turn slight right,arrive|

And the test reports turn right for the route a->e, where before it said slight right.

If you change the turn angles, obviously you can expect changes in the distinction between slight right and right. In such a case it is, of course, reasonable to change the expected route to report right instead of slight right. You should consider inspecting the actual turn angles at b to see if you feel that change is justified.

However, you should never adjust the test itself. If you look at a failure, the other way around

Given a grid size of 5 m
+Given the node map
+"""
+a - b - - - - - - c
+     \\  
+      d - - - - - e
+"""
+
+When I route I should get
+ | waypoints | route       | turns                   |
+ | a,e       | abc,bde,bde | depart,turn right,arrive|

where we see a slight right, over the expected right. We could be tempted to adjust the grid size (e.g. from 10 m to 20 meters).

Such a change would fundamentally alter the tests, though. Since the part b-d is a short offset, when we are looking at a grid of size 5 m, the angle calculation will try and compensate for this offset.

In this case we would see a very slight turn angle. If your change now reports different turn angles, you can of course change the expected result. But you should not adjust the grid size. The test would be testing turn angles of 180 and 100 degrees, instead of 180 and 160.

Consider Post-Processing Impacts ​

Some changes you might see could look completely unrelated. To understand the impact of your changes, you can make use of the debugging utilities you can find in util/debug.hpp (and potentially other related headers).

If your test is inspecting a series of turns (remember, a turn does not necessarily equals an instruction), you could see interaction with post-processing. To see the unprocessed turns, you should print the steps at the end of step assembly (assembleSteps in engine/guidance/assemble_steps.hpp).

If you see unexpected changes, you can consider adding the locations field to your test to study what location a turn is reported at.

To study a test without post-processing impacts, you can create a copy of the case on a very large grid (like 2000 meters). In such a grid, turn collapsing would be essentially disabled.

Sadly, there is no general guideline.

Use Caution ​

If in doubt, ask another person. Inspect as much of the data as possible (e.g. print un-collapsed steps, turn angles and so on) and use your best judgement, if the new result seems justified.

Building OSRM for Windows ​

There is experimental support for building OSRM on Windows.

Dependencies ​

You will need a modern Windows development stack (e.g. Visual Studio 17). The published binaries are built with Windows Server 2025 Github hosted runners.

Dependencies are managed via vcpkg in manifest mode (see vcpkg.json at the repo root). The baseline commit is pinned in vcpkg-configuration.json.

Prerequisites ​

  1. Install Visual Studio 2022 with the "Desktop development with C++" workload.
  2. Clone vcpkg and bootstrap it:
bat
git clone https://github.com/microsoft/vcpkg.git C:\\vcpkg
+C:\\vcpkg\\bootstrap-vcpkg.bat
+set VCPKG_ROOT=C:\\vcpkg

Building ​

From a x64 Native Tools Command Prompt for VS 2022 at the repo root:

bat
cmake --preset ci-windows -DENABLE_NODE_BINDINGS=ON
+cmake --build --preset ci-windows

The first configure will build every dependency from source, which takes a while. Subsequent configures reuse vcpkg's binary cache.

Single OSRM Configuration ​

An OSRM configuration consists of a routing algorithm and a data load method. OSRM currently supports the routing algorithms:

  • ch (Contraction Hierarchy), and
  • mld (Multi-Level-Dijkstra)

and the data load methods:

  • directly (load the files into memory),
  • mmap (use memory mapped files), and
  • datastore (use shared memory).

To test all scenarios with a single OSRM configuration, say:

bash
$ npx cucumber-js -p home -p mld -p mmap --parallel 8 --fail-fast

Explanations follow:

Profiles ​

Profiles are chosen with the -p commandline argument. Cucumber profiles allow you to change multiple configuration items with just one commandline argument. If you set more than one profile they are all merged into one configuration.

Note: Cucumber profiles should not be confused with OSRM profiles. Cucumber profiles are defined in cucumber.mjs. OSRM profiles reside in the profiles/*.lua files.

Our implementation offers following stock profiles. You should always use one base profile followed by zero or more additional profiles.

Name
homeBase profile to use on a developer machine
githubBase profile to use on the github CI server
chAdditional profile that selects the CH algorithm
mldAdditional profile that selects the MLD algorithm
mmapAdditional profile that selects the mmap data load method
directlyAdditional profile that selects the directly data load method
datastoreAdditional profile that selects the datastore data load method
stressAdditional profile that selects only @stress tests
todoAdditional profile that selects only @todo tests
allAdditional profile that selects all tests

Arguments ​

Here is a description of all arguments you can pass to Cucumber. The interesting ones probably are: --fail-fast, --format, --parallel, and --tags.

Note: when using --parallel N make sure there are N contiguous free ports at the configured port number (eg. at ports 5000--5000+N).

All OSRM Configurations ​

We provide a shortcut to run all 6 configurations:

bash
$ npm test

This is how the tests are run on the CI server. You can pass the same arguments as mentioned above.

Cache ​

To speed up subsequent runs with the same parameters, the files generated by Cucumber and the by the OSRM extraction chain are held in a cache directory. This cache is located by default in test/cache and should be cleaned periodically:

bash
$ rm -rf test/cache

Configuration ​

The whole configuration is done in cucumber.mjs. You can either edit worldParameters in cucumber.mjs or use environment variables to override single defaults.

worldParametersEnvironment VariableDefaults to
CUCUMBER_TIMEOUT5000Scenario timeout in ms.
httpTimeoutCUCUMBER_HTTP_TIMEOUT2000HTTP timeout in ms.
testPathCUCUMBER_TEST_PATHtestThe test directory
profilesPathCUCUMBER_PROFILES_PATHprofilesThe profiles directory
logsPathCUCUMBER_LOGS_PATHtest/logsThe logs directory
cachePathCUCUMBER_CACHE_PATHtest/cacheThe cache directory
buildPathOSRM_BUILD_DIRbuildPath to the binaries
loadMethodOSRM_LOAD_METHODdatastoreData load method
algorithmOSRM_ALGORITHMchRouting algorithm
ipOSRM_IP127.0.0.1IP Address
portOSRM_PORT5000IP Port

The default Cucumber timeout can be changed by setting the environment variable CUCUMBER_TIMEOUT. This is discouraged, because the default timeout of 5 seconds is plenty for the problem sizes we are dealing with. The probable reasons for a test timing out are that osrm-routed died or that sync between osrm-datastore and osrm-routed was lost.

Other environment variables ​

OSRM_RASTER_SOURCE is set by 'Given the raster source' and is supposed to be read back in your profiles/*.lua profile by os.getenv('OSRM_RASTER_SOURCE').

OSRM_PROFILE See: Pull Request #4516

Tags ​

Single scenarios or whole feature files can be tagged. Tag names can be selected arbitrarily although it is best to conform to the tags already used. Eg. the tag @guidance can be used to run only those tests related to the guidance feature:

bash
$ npm test -- --tags @guidance

We also support following special tags:

TagA scenario thus tagged ...
@isolatedwill not run while any other scenario is running in parallel
@with_(datastore|directly|mmap)will be executed iff the load method matches
@no_(datastore|directly|mmap)will be executed unless the load method matches
@with_(ch|mld)will be executed iff the algorithm matches
@no_(ch|mld)will be executed unless the algorithm matches
@with_(linux|darwin|win32)will be executed iff the OS matches
@no_(linux|darwin|win32)will be executed unless the OS matches

A test that calls osrm-datastore --spring-clean should not run concurrently with any other test, thus the tag @isolated should be applied. A test that runs or kills osrm-routed should not run while testing the datastore load method, and thus should be labeled with the tag @no_datastore.

Developing / Debugging guidance code ​

When changing guidance code, it is easy to introduce problems somewhere in the network. To get a better feeling of how your changes impact the OSRM experience, we offer ways of generating geojson output to inspect (e.g. with Mapbox Studio). When you do changes, make sure to inspect a few areas for the impact of the changes.

How to use GeoJson-Debugging ​

This is a short guide to describe usage of our GeoJson debug logging mechanism. It is synchronized to guarantee thread-safe logging.

Outputting into a single file ​

To use it, the inclusion of geojson_debug_logger.hpp geojson_debug_policies.hpp from the util directory is required.

Geojson debugging requires a few simple steps to output data into a feature collection.

  • Create a Scoped Guard that lives through the process and provide it with all required datastructures (it needs to span the lifetime of all your logging efforts)
  • At the location of the output, simply call Write with your own parameters.

A guard (ScopedGeojsonLoggerGuard) requires a logging policy. Per default we provide a way of printing out node-ids as coordinates.

The initialisation to do so looks like this: util::ScopedGeojsonLoggerGuard<util::NodeIdVectorToLineString> geojson_guard( "debug.geojson", data-for-conversion); Make sure to give the guard a name, so it actually gets a lifetime.

The field data-for-conversion can be an arbitrary long set of features and needs to match the parameters used for constructing our policy (in this case util::NodeIdVectorToLineString).

The policy itself offers a operator() accepting a vector of NodeID.

For outputting data into our file (debug.geojson), we simply need to call the matching logging routine of the guard: util::ScopedGeojsonLoggerGuard<util::NodeIdVectorToLineString>::Write(list_of_node_ids); (or guard.Write(list_of_node_ids) if you created an instance).

Possible Scopeguard Location ​

Think of the scopeguard as you would do of any reference. If you want to access logging during a call, the guard object must be alive and valid.

As an example: a good location to create a scopeguard to log decisions in the edge-based-graph-factory would be right before we run it (here). If you put util::ScopedGeojsonLoggerGuard<util::NodeIdVectorToLineString> geojson_guard( "debug.geojson", node_coordinate_vector); at that location, you can then print util::ScopedGeojsonLoggerGuard<util::NodeIdVectorToLineString>::Write(list_of_node_ids); anywhere within the edge-based-graph-factory.

This location would enable calls for all guidance related pre-processing which is called in the edge-based-graph-factory. Logging any turn-handler decisions, for example, would now be possible.

Limitations ​

GeoJson debugging requires a single GeoJsonGuard (ScopedGeojsonLoggerGuard) for each desired output file. For each set of template parameters, only the most recent guard will actually produce output.

util::ScopedGeojsonLoggerGuard<util::NodeIdVectorToLineString> geojson_guard( "debug.geojson", data-for-conversion);

util::ScopedGeojsonLoggerGuard<util::NodeIdVectorToLineString> geojson_guard( "debug-2.geojson", data-for-conversion);

Will not provide a way to write into two files, but only debug-2 will actually contain features.

We cannot nest these calls.

If we want to use the same policy for multiple files, we need to use different template parameters both for the logger and the guard.

util::ScopedGeojsonLoggerGuard<util::NodeIdVectorToLineString,0> geojson_guard( "debug.geojson", data-for-conversion);

util::ScopedGeojsonLoggerGuard<util::NodeIdVectorToLineString,1> geojson_guard( "debug-2.geojson", data-for-conversion);

as well as,

util::ScopedGeojsonLoggerGuard<util::NodeIdVectorToLineString,0>::Write(list_of_node_ids);

util::ScopedGeojsonLoggerGuard<util::NodeIdVectorToLineString,1>::Write(list_of_node_ids);

OSRM HTTP server ​

The built-in HTTP server is a basic HTTP/1.0 server that supports a 'keep-alive' extension. Persistent connections are limited to 512 requests per connection and allow no more than 5 seconds between requests.

General options ​

All OSRM HTTP requests use a common structure.

The following syntax applies to all services, except as noted.

Requests ​

GET
/{service}/{version}/{profile}/{coordinates}[.{format}]?option=value&option=value
ParameterDescription
serviceOne of the following values: route, nearest, table, match, trip, tile
versionVersion of the protocol implemented by the service. v1 for all OSRM 5.x installations
profileMode of transportation, is determined statically by the Lua profile that is used to prepare the data using osrm-extract. Typically car, bike or foot if using one of the supplied profiles.
coordinatesString of format {longitude},{latitude};{longitude},{latitude}[;{longitude},{latitude} ...] or polyline({polyline}) or polyline6({polyline6}).
formatjson or flatbuffers. This parameter is optional and defaults to json.

Passing any option=value is optional. polyline follows Google's polyline format with precision 5 by default and can be generated using this package.

To pass parameters to each location some options support an array-like encoding:

Request options

OptionValuesDescription
bearings{bearing};{bearing}[;{bearing} ...]Limits the search to segments with given bearing in degrees towards true north in a clockwise direction.
radiuses{radius};{radius}[;{radius} ...]Limits the search to given radius in meters.
generate_hintstrue (default), falseAdds a Hint to the response which can be used in subsequent requests, see hints parameter.
hints{hint};{hint}[;{hint} ...]Hint from previous request to derive position in street network.
approaches{approach};{approach}[;{approach} ...]Restrict the direction on the road network at a waypoint, relative to the input coordinate.
exclude{class}[,{class}]Additive list of classes to avoid, the order does not matter.
snappingdefault (default), anyDefault snapping avoids is_startpoint (see profile) edges, any will snap to any edge in the graph
skip_waypointstrue, false (default)Removes waypoints from the response. Waypoints are still calculated, but not serialized. Could be useful in case you are interested in some other part of the response and do not want to transfer waste data.

Where the elements follow the following format:

ElementValues
bearing{value},{range} integer 0 .. 360,integer 0 .. 180
radiusdouble >= 0 or unlimited (default)
hintBase64 string
approachcurb, opposite or unrestricted (default)
classA class name determined by the profile or none.
{option}={element};{element}[;{element} ... ]

The number of elements must match exactly the number of locations (except for generate_hints and exclude). If you don't want to pass a value but instead use the default you can pass an empty element.

Example: 2nd location uses the default value for option:

{option}={element};;{element}

Example Requests ​

bash

Responses ​

Code ​

Every response object has a code property containing one of the strings below or a service dependent code:

TypeDescription
OkRequest could be processed as expected.
InvalidUrlURL string is invalid.
InvalidServiceService name is invalid.
InvalidVersionVersion is not found.
InvalidOptionsOptions are invalid.
InvalidQueryThe query string is syntactically malformed.
InvalidValueThe successfully parsed query parameters are invalid.
NoSegmentOne of the supplied input coordinates could not snap to the street segment.
TooBigThe request size violates one of the service-specific request size restrictions.
DisabledDatasetThe request tried to access a disabled dataset.
  • message is an optional human-readable error message. All other status types are service-dependent.
  • In case of an error the HTTP status code will be 400. Otherwise, the HTTP status code will be 200 and code will be Ok.

Data version ​

Every response object has a data_version property containing a timestamp from the original OpenStreetMap file. This field is optional. It can be omitted if the data_version parameter was not set on the osrm-extract stage or the OSM file has not osmosis_replication_timestamp section.

Example response ​

json
{
+"code": "Ok",
+"message": "Everything worked",
+"data_version": "2017-11-17T21:43:02Z"
+}

Services ​

Nearest service ​

Snaps a coordinate to the street network and returns the nearest n matches.

GET
http://{server}/nearest/v1/{profile}/{coordinates}.json?number={number}

Where coordinates only supports a single {longitude},{latitude} entry.

In addition to the general options the following options are supported for this service:

OptionValuesDescription
numberinteger >= 1 (default 1)Number of nearest segments that should be returned.

As waypoints is a single thing returned by that service, using it with the option skip_waypoints set to true is quite useless, but still possible. In that case, only the code field will be returned.

Response

  • code if the request was successful Ok otherwise see the service dependent and general status codes.
  • waypoints array of Waypoint objects sorted by distance to the input coordinate. Each object has at least the following additional properties:
    • nodes: Array of OpenStreetMap node ids.

Match service ​

Map matching matches/snaps given GPS points to the road network in the most plausible way. Please note the request might result in multiple sub-traces. Large jumps in the timestamps (> 60s) or improbable transitions lead to trace splits if a complete matching could not be found. The algorithm might not be able to match all points. Outliers are removed if they can not be matched successfully.

GET
/match/v1/{profile}/{coordinates}?steps={true|false}&geometries={polyline|polyline6|geojson}&overview={simplified|full|false}&annotations={true|false}

In addition to the general options the following options are supported for this service:

OptionValuesDescription
stepstrue, false (default)Returned route steps for each route
geometriespolyline (default), polyline6, geojsonReturned route geometry format (influences overview and per step)
annotationstrue, false (default), nodes, distance, duration, datasources, weight, speedReturns additional metadata for each coordinate along the route geometry.
overviewsimplified (default), full, false, by_legsAdd overview geometry either full, simplified according to highest zoom level it could be displayed on, not at all, or split by leg.
timestamps{timestamp};{timestamp}[;{timestamp} ...]Timestamps for the input locations in seconds since UNIX epoch. Timestamps need to be monotonically increasing.
radiuses{radius};{radius}[;{radius} ...]Standard deviation of GPS precision used for map matching. If applicable use GPS accuracy.
gapssplit (default), ignoreAllows the input track splitting based on huge timestamp gaps between points.
tidytrue, false (default)Allows the input track modification to obtain better matching quality for noisy tracks.
waypoints{index};{index};{index}...Treats input coordinates indicated by given indices as waypoints in returned Match object. Default is to treat all input coordinates as waypoints.
ParameterValues
timestampinteger seconds since UNIX epoch
radiusdouble >= 0 (default 5m)

The radius for each point should be the standard error of the location measured in meters from the true location. Use Location.getAccuracy() on Android or CLLocation.horizontalAccuracy on iOS. This value is used to determine which points should be considered as candidates (larger radius means more candidates) and how likely each candidate is (larger radius means far-away candidates are penalized less). The area to search is chosen such that the correct candidate should be considered 99.9% of the time (for more details see this ticket).

Response

  • code if the request was successful Ok otherwise see the service dependent and general status codes.
  • tracepoints: Array of Waypoint objects representing all points of the trace in order. If the tracepoint was omitted by map matching because it is an outlier, the entry will be null. Each Waypoint object has the following additional properties:
    • matchings_index: Index to the Route object in matchings the sub-trace was matched to.
    • waypoint_index: Index of the waypoint inside the matched route.
    • alternatives_count: Number of probable alternative matchings for this tracepoint. A value of zero indicates that this point was matched unambiguously. Split the trace at these points for incremental map matching.
  • matchings: An array of Route objects that assemble the trace. Each Route object has the following additional properties:
    • confidence: Confidence of the matching. float value between 0 and 1. 1 is very confident that the matching is correct.

In case of error the following codes are supported in addition to the general ones:

TypeDescription
NoMatchNo matchings found.

All other properties might be undefined.

Trip service ​

The trip plugin solves the Traveling Salesman Problem using a greedy heuristic (farthest-insertion algorithm) for 10 or more waypoints and uses brute force for less than 10 waypoints. The returned path does not have to be the fastest one. As TSP is NP-hard it only returns an approximation. Note that all input coordinates have to be connected for the trip service to work.

GET
/trip/v1/{profile}/{coordinates}?roundtrip={true|false}&source={any|first}&destination={any|last}&steps={true|false}&geometries={polyline|polyline6|geojson}&overview={simplified|full|false}&annotations={true|false}

In addition to the general options the following options are supported for this service:

OptionValuesDescription
roundtriptrue (default), falseReturned route is a roundtrip (route returns to first location)
sourceany (default), firstReturned route starts at any or first coordinate
destinationany (default), lastReturned route ends at any or last coordinate
stepstrue, false (default)Returned route instructions for each trip
annotationstrue, false (default), nodes, distance, duration, datasources, weight, speedReturns additional metadata for each coordinate along the route geometry.
geometriespolyline (default), polyline6, geojsonReturned route geometry format (influences overview and per step)
overviewsimplified (default), full, false, by_legsAdd overview geometry either full, simplified according to highest zoom level it could be displayed on, not at all, or split by leg.

Fixing Start and End Points

It is possible to explicitly set the start or end coordinate of the trip. When the source is set to first, the first coordinate is used as the start coordinate of the trip in the output. When the destination is set to last, the last coordinate will be used as the destination of the trip in the returned output. If you specify any, any of the coordinates can be used as the first or last coordinate in the output.

However, if source=any&destination=any the returned round-trip will still start at the first input coordinate by default.

Currently, not all combinations of roundtrip, source, and destination are supported. Right now, the following combinations are possible:

roundtripsourcedestinationsupported
truefirstlastyes
truefirstanyyes
trueanylastyes
trueanyanyyes
falsefirstlastyes

Tile service ​

This service generates Mapbox Vector Tiles that can be viewed with a vector-tile capable slippy-map viewer. The tiles contain road geometries and metadata that can be used to examine the routing graph. The tiles are generated directly from the data in-memory, so are in sync with actual routing results, and let you examine which roads are actually routable, and what weights they have applied.

GET
/tile/v1/{profile}/tile({x},{y},{zoom}).mvt

The x, y, and zoom values are the same as described at https://wiki.openstreetmap.org/wiki/Slippy_map_tilenames, and are supported by vector tile viewers like Mapbox GL JS.

Example request ​

bash
# This fetches a Z=13 tile for downtown San Francisco:
+curl 'http://router.project-osrm.org/tile/v1/car/tile(1310,3166,13).mvt'

Example response ​

example rendered tilehttp://map.project-osrm.org/debug/#14.33/52.5212/13.3919

The response object is either a binary encoded blob with a Content-Type of application/x-protobuf, or a 404 error. Note that OSRM is hard-coded to only return tiles from zoom level 12 and higher (to avoid accidentally returning extremely large vector tiles).

Vector tiles contain two layers:

speeds layer:

PropertyTypeDescription
speedintegerthe speed on that road segment, in km/h
is_smallbooleanwhether this segment belongs to a small (< 1000 node) strongly connected component
datasourcestringthe source for the speed value (normally lua profile unless you're using the traffic update feature, in which case it contains the stem of the filename that supplied the speed value for this segment
durationfloathow long this segment takes to traverse, in seconds. This value is to calculate the total route ETA.
weight integerhow long this segment takes to traverse, in units (may differ from duration when artificial biasing is applied in the Lua profiles). ACTUAL ROUTING USES THIS VALUE.
namestringthe name of the road this segment belongs to
ratefloatthe value of length/weight - analogous to speed, but using the weight value rather than duration, rounded to the nearest integer
is_startpointbooleanwhether this segment can be used as a start/endpoint for routes

turns layer:

PropertyTypeDescription
bearing_inintegerthe absolute bearing that approaches the intersection. -180 to +180, 0 = North, 90 = East
turn_angleintegerthe angle of the turn, relative to the bearing_in. -180 to +180, 0 = straight ahead, 90 = 90-degrees to the right
costfloatthe time we think it takes to make that turn, in seconds. May be negative, depending on how the data model is constructed (some turns get a "bonus").
weightfloatthe weight we think it takes to make that turn. May be negative, depending on how the data model is constructed (some turns get a "bonus"). ACTUAL ROUTING USES THIS VALUE
typestringthe type of this turn - values like turn, continue, etc. See the StepManeuver for a partial list, this field also exposes internal turn types that are never returned with an API response
modifierstringthe direction modifier of the turn (left, sharp left, etc)

StepManeuver object ​

Properties

  • location: A [longitude, latitude] pair describing the location of the turn.
  • bearing_before: The clockwise angle from true north to the direction of travel immediately before the maneuver. Range 0-359.
  • bearing_after: The clockwise angle from true north to the direction of travel immediately after the maneuver. Range 0-359.
  • type A string indicating the type of maneuver. new identifiers might be introduced without API change Types unknown to the client should be handled like the turn type, the existence of correct modifier values is guaranteed.
typeDescription
turna basic turn into the direction of the modifier
new nameno turn is taken/possible, but the road name changes. The road can take a turn itself, following modifier.
departindicates the departure of the leg
arriveindicates the destination of the leg
mergemerge onto a street (e.g. getting on the highway from a ramp, the modifier specifies the direction of the merge)
rampDeprecated. Replaced by on_ramp and off_ramp.
on ramptake a ramp to enter a highway (direction given my modifier)
off ramptake a ramp to exit a highway (direction given my modifier)
forktake the left/right side at a fork depending on modifier
end of roadroad ends in a T intersection turn in direction of modifier
use laneDeprecated replaced by lanes on all intersection entries
continueTurn in direction of modifier to stay on the same road
roundabouttraverse roundabout, if the route leaves the roundabout there will be an additional property exit for exit counting. The modifier specifies the direction of entering the roundabout.
rotarya traffic circle. While very similar to a larger version of a roundabout, it does not necessarily follow roundabout rules for right of way. It can offer rotary_name and/or rotary_pronunciation parameters (located in the RouteStep object) in addition to the exit parameter (located on the StepManeuver object).
roundabout turnDescribes a turn at a small roundabout that should be treated as a normal turn. The modifier indicates the turn direction. Example instruction: At the roundabout turn left.
notificationnot an actual turn but a change in the driving conditions. For example the travel mode or classes. If the road takes a turn itself, the modifier describes the direction
exit roundaboutDescribes a maneuver exiting a roundabout (usually preceded by a roundabout instruction)
exit rotaryDescribes the maneuver exiting a rotary (large named roundabout)

Please note that even though there are new name and notification instructions, the mode and name can change between all instructions. They only offer a fallback in case nothing else is to report.

  • modifier An optional string indicating the direction change of the maneuver.
modifierDescription
uturnindicates the reversal of direction
sharp righta sharp right turn
righta normal turn to the right
slight righta slight turn to the right
straightno relevant change in direction
slight lefta slight turn to the left
lefta normal turn to the left
sharp lefta sharp turn to the left

The list of turns without a modifier is limited to: depart/arrive. If the source/target location is close enough to the depart/arrive location, no modifier will be given.

The meaning depends on the type property.

typeDescription
turnmodifier indicates the change in direction accomplished through the turn
depart/arrivemodifier indicates the position of departure point and arrival point in relation to the current direction of travel
  • exit An optional integer indicating the number of the exit to take. The property exists for the roundabout / rotary property: Number of the roundabout exit to take. If an exit is undefined the destination is on the roundabout.

New properties (potentially depending on type) may be introduced in the future without an API version change.

Lane object ​

A Lane represents a turn lane at the corresponding turn location.

Properties

  • indications: an indication (e.g. marking on the road) specifying the turn lane. A road can have multiple indications (e.g. an arrow pointing straight and left). The indications are given in an array, each containing one of the following types. Further indications might be added on without an API version change.
valueDescription
noneNo dedicated indication is shown.
uturnAn indication signaling the possibility to reverse (i.e. fully bend arrow).

Intersection object ​

An intersection gives a full representation of any cross-way the path passes by. For every step, the very first intersection (intersections[0]) corresponds to the location of the StepManeuver. Further intersections are listed for every cross-way until the next turn instruction.

Properties

  • location: A [longitude, latitude] pair describing the location of the turn.
  • bearings: A list of bearing values (e.g. [0,90,180,270]) that are available at the intersection. The bearings describe all available roads at the intersection. Values are between 0-359 (0=true north)
  • classes: An array of strings signifying the classes (as specified in the profile) of the road exiting the intersection.
  • entry: A list of entry flags, corresponding in a 1:1 relationship to the bearings. A value of true indicates that the respective road could be entered on a valid route. false indicates that the turn onto the respective road would violate a restriction.
  • in: index into bearings/entry array. Used to calculate the bearing just before the turn. Namely, the clockwise angle from true north to the direction of travel immediately before the maneuver/passing the intersection. Bearings are given relative to the intersection. To get the bearing in the direction of driving, the bearing has to be rotated by a value of 180. The value is not supplied for depart maneuvers.
  • out: index into the bearings/entry array. Used to extract the bearing just after the turn. Namely, The clockwise angle from true north to the direction of travel immediately after the maneuver/passing the intersection. The value is not supplied for arrive maneuvers.

+    "in":0,
+    "out":2,
+    "bearings":[60,150,240,330],

Waypoint object ​

The object is used to describe the waypoint on a route.

Properties

  • name Name of the street the coordinate snapped to
  • location Array that contains the [longitude, latitude] pair of the snapped coordinate
  • distance The distance, in meters, from the input coordinate to the snapped coordinate
  • hint Unique internal identifier of the segment (ephemeral, not constant over data updates) This can be used on subsequent requests to significantly speed up the query and to connect multiple services. E.g. you can use the hint value obtained by the nearest query as hint values for route inputs.

Example ​

json
{
+   "hint" : "KSoKADRYroqUBAEAEAAAABkAAAAGAAAAAAAAABhnCQCLtwAA_0vMAKlYIQM8TMwArVghAwEAAQH1a66g",

+   "location" : [
+      13.388799,
+      52.517033
+   ]
+}

Flatbuffers format ​

The default response format is json, but OSRM supports binary flatbuffers format, which is much faster in serialization/deserialization, comparing to json.

The format itself is described in message descriptors, located at include/engine/api/flatbuffers directory. Those descriptors could be compiled to provide protocol parsers in Go/Javascript/Typescript/Java/Dart/C#/Python/Lobster/Lua/Rust/PHP/Kotlin. Precompiled protocol parser for C++ is supplied with OSRM.

Flatbuffers format provides exactly the same data, as json format with a slightly different layout, which was optimized to minimize in-transfer size.

Root object ​

Root object is the only object, available from a 'raw' flatbuffers buffer. It can be constructed with a following call:

     auto osrm = osrm::engine::api::fbresult::GetFBResult(some_input_buffer);
+

Properties

  • error: bool Marks response as erroneous. An erroneous response should include the code fieldset, all the other fields may not be present.
  • code: Error Error description object, only present, when error is true
  • waypoints: [Waypoint] Array of Waypoint objects. Should present for every service call, unless skip_waypoints is set to true. Table service will put sources array here.
  • routes: [RouteObject] Array of RouteObject objects. May be empty or absent. Should present for Route/Trip/Match services call.
  • table: Table Table object, may absent. Should be present in case of Table service call.

Error object ​

Contains error information.

Properties

  • code: string Error code
  • message: string Detailed error message

Waypoint object ​

Almost the same as json Waypoint object. The following properties differ:

  • location: Position Same as json location field, but different format.
  • nodes: Uint64Pair Same as json nodes field, but different format.

RouteObject object ​

Almost the same as json Route object. The following properties differ:

  • polyline: string Same as json geometry.polyline or geometry.polyline6 fields. One field for both formats.
  • coordinates: [Position] Same as json geometry.coordinates field, but different format.
  • legs: [Leg] Array of Leg objects.

Leg object ​

Almost the same as json Leg object. The following properties differ:

  • annotations: Annotation Same as json annotation field, but different format.
  • steps: [Step] Same as step annotation field, but different format.

Step object ​

Almost the same as json Step object. The following properties differ:

  • polyline: string Same as json geometry.polyline or geometry.polyline6 fields. One field for both formats.
  • coordinates: [Position] Same as json geometry.coordinates field, but different format.
  • maneuver: StepManeuver Same as json maneuver field, but different format.

Introduction ​

OSRM can be used as a library (libosrm) via C++ instead of using it through the HTTP interface and osrm-routed. This allows for fine-tuning OSRM and has much less overhead. Here is a quick introduction into how to use libosrm in the current version.

Take a look at the example code that lives in the example directory. Here is all you ever wanted to know about libosrm, that is a short description of what the types do and where to find documentation on it:

Important interface objects ​

  • EngineConfig - for initializing an OSRM instance we can configure certain properties and constraints. E.g. the storage config is the base path such as france.osm.osrm from which we derive and load france.osm.osrm.* auxiliary files. This also lets you set constraints such as the maximum number of locations allowed for specific services.

  • OSRM - this is the main Routing Machine type with functions such as Route and Table. You initialize it with a EngineConfig. It does all the heavy lifting for you. Each function takes its own parameters, e.g. the Route function takes RouteParameters, and a out-reference to a JSON result that gets filled. The return value is a Status, indicating error or success.

  • Status - this is a type wrapping Error or Ok for indicating error or success, respectively.

  • TableParameters - this is an example of parameter types the Routing Machine functions expect. In this case Table expects its own parameters as TableParameters. You can see it wrapping two vectors, sources and destinations --- these are indices into your coordinates for the table service to construct a matrix from (empty sources or destinations means: use all of them). If you ask yourself where coordinates come from, you can see TableParameters inheriting from BaseParameters.

  • BaseParameters - this most importantly holds coordinates (and a few other optional properties that you don't need for basic usage); the specific parameter types inherit from BaseParameters to get these member attributes. That means your TableParameters type has coordinates, sources and destinations member attributes (and a few other that we ignore for now).

  • Coordinate - this is a wrapper around a (longitude, latitude) pair. We really don't care about (lon, lat) vs (lat, lon) but we don't want you to accidentally mix them up, so both latitude and longitude are strictly typed wrappers around integers (fixed notation such as 13423240) and floating points (floating notation such as 13.42324).

  • Parameters for other services - here are all other *Parameters you need for other Routing Machine services.

  • JSON - this is a sum type resembling JSON. The Routing Machine service functions take a out-ref to a JSON result and fill it accordingly. It is currently implemented using std::variant. There are two ways to work with this sum type: either provide a visitor that acts on each type on visitation (with std::visit) or use the std::get function in case you're sure about the structure. The JSON structure is written down in the HTTP API.

Example ​

See the example folder in the OSRM repository.

Workflow ​

  • Create an OSRM instance initialized with a EngineConfig
  • Call the service function on the OSRM object providing service specific *Parameters
  • Check the return code and use the JSON result

OSRM ​

The OSRM method is the main constructor for creating an OSRM instance. An OSRM instance requires a .osrm.* dataset(.osrm.* because it contains several files), which is prepared by the OSRM toolchain. You can create such a .osrm.* dataset by running the OSRM binaries we ship in node_modules/osrm/lib/binding_napi_v8/ and default profiles (e.g. for setting speeds and determining road types to route on) in node_modules/osrm/profiles/:

node_modules/osrm/lib/binding_napi_v8/osrm-extract data.osm.pbf -p node_modules/osrm/profiles/car.lua
+node_modules/osrm/lib/binding_napi_v8/osrm-contract data.osrm
+

Consult the osrm-backend documentation for further details.

Once you have a complete network.osrm.* dataset, you can calculate routes in javascript with this object.

javascript
var osrm = new OSRM('network.osrm');

Parameters ​

  • options (Object | String) Options for creating an OSRM object or string to the .osrm file. (optional, default {shared_memory:true})

    • options.algorithm String? The algorithm to use for routing. Can be 'CH', or 'MLD'. Default is 'CH'. Make sure you prepared the dataset with the correct toolchain.

    • options.mmap_memory Boolean? Map on-disk files to virtual memory addresses (mmap), rather than loading into RAM.
    • options.path String? The path to the .osrm files. This is mutually exclusive with setting {options.shared_memory} to true.

+var options = {
+  coordinates: [
+    [13.388860,52.517037],
+    [13.397634,52.529407],

tile ​

This generates Mapbox Vector Tiles that can be viewed with a vector-tile capable slippy-map viewer. The tiles contain road geometries and metadata that can be used to examine the routing graph. The tiles are generated directly from the data in-memory, so are in sync with actual routing results, and let you examine which roads are actually routable, and what weights they have applied.

Parameters ​

Examples ​

javascript
var osrm = new OSRM('network.osrm');
+osrm.tile([0, 0, 0], function(err, response) {

+});

Returns Buffer contains a Protocol Buffer encoded vector tile.

match ​

Map matching matches given GPS points to the road network in the most plausible way. Please note the request might result multiple sub-traces. Large jumps in the timestamps (>60s) or improbable transitions lead to trace splits if a complete matching could not be found. The algorithm might not be able to match all points. Outliers are removed if they can not be matched successfully.

Parameters ​

  • options Object Object literal containing parameters for the match query.

    • options.coordinates Array? The coordinates this request will use, coordinates as [{lon},{lat}] values, in decimal degrees.
    • options.bearings Array? Limits the search to segments with given bearing in degrees towards true north in clockwise direction. Can be null or an array of [{value},{range}] with integer 0 .. 360,integer 0 .. 180.

    • options.overview String Add overview geometry either full, simplified according to highest zoom level it could be display on, or not at all (false). (optional, default simplified)
    • options.timestamps Array<Number>? Timestamp of the input location (integers, UNIX-like timestamp).
    • options.radiuses Array? Standard deviation of GPS precision used for map matching. If applicable use GPS accuracy. Can be null for default value 5 meters or double >= 0.
    • options.gaps String Allows the input track splitting based on huge timestamp gaps between points. Either split or ignore. (optional, default split)
    • options.tidy Boolean Allows the input track modification to obtain better matching quality for noisy tracks. (optional, default false)
    • options.waypoints Array? Indices to coordinates to treat as waypoints. If not supplied, all coordinates are waypoints. Must include first and last coordinate index.
    • options.snapping String? Which edges can be snapped to, either default, or any. default only snaps to edges marked by the profile as is_startpoint, any will allow snapping to any edge in the routing graph.

  • callback Function

Examples ​

javascript
var osrm = new OSRM('network.osrm');
+var options = {
+    coordinates: [[13.393252,52.542648],[13.39478,52.543079],[13.397389,52.542107]],
+    timestamps: [1424684612, 1424684616, 1424684620]
+};
+osrm.match(options, function(err, response) {
+    if (err) throw err;
+    console.log(response.tracepoints); // array of Waypoint objects
+    console.log(response.matchings); // array of Route objects
+});

Returns Object containing tracepoints and matchings. tracepoints Array of Ẁaypoint objects representing all points of the trace in order. If the trace point was omitted by map matching because it is an outlier, the entry will be null. Each Waypoint object has the following additional properties, 1) matchings_index: Index to the Route object in matchings the sub-trace was matched to, 2) waypoint_index: Index of the waypoint inside the matched route. 3) alternatives_count: Number of probable alternative matchings for this trace point. A value of zero indicate that this point was matched unambiguously. Split the trace at these points for incremental map matching. matchings is an array of Route objects that assemble the trace. Each Route object has an additional confidence property, which is the confidence of the matching. float value between 0 and 1. 1 is very confident that the matching is correct.

trip ​

The trip plugin solves the Traveling Salesman Problem using a greedy heuristic (farthest-insertion algorithm) for 10 or * more waypoints and uses brute force for less than 10 waypoints. The returned path does not have to be the shortest path, * as TSP is NP-hard it is only an approximation.

Note that all input coordinates have to be connected for the trip service to work. Currently, not all combinations of roundtrip, source and destination are supported. Right now, the following combinations are possible:

roundtripsourcedestinationsupported
truefirstlastyes
truefirstanyyes
trueanylastyes
trueanyanyyes
falsefirstlastyes
falsefirstanyno
falseanylastno
falseanyanyno

    • plugin_config.format String? The format of the result object to various API calls. Valid options are object (default if options.format is json), which returns a standard Javascript object, as described above, and buffer(default if options.format is flatbuffers), which will return a NodeJS Buffer object, containing a JSON string or Flatbuffers object. The latter has the advantage that it can be immediately serialized to disk/sent over the network, and the generation of the string is performed outside the main NodeJS event loop. This option is ignored by the tile plugin. Also note that options.format set to flatbuffers cannot be used with plugin_config.format set to object. json_buffer is deprecated alias for buffer.

Examples ​

javascript
var osrm = new OSRM('network.osrm');

+  coordinates: [

OSRM profiles ​

OSRM supports "profiles". Profiles represent routing behavior for different transport modes like car, bike and foot. You can also create profiles for variations like a fastest/shortest car profile or fastest/safest/greenest bicycles profile.

A profile describes whether or not it's possible to route along a particular type of way, whether we can pass a particular node, and how quickly we'll be traveling when we do. This feeds into the way the routing graph is created and thus influences the output routes.

Available profiles ​

Out-of-the-box OSRM comes with profiles for car, bicycle and foot. You can easily modify these or create new ones if you like.

Profiles have a 'lua' extension, and are placed in 'profiles' directory.

When running OSRM preprocessing commands you specify the profile with the --profile (or the shorthand -p) option, for example:

osrm-extract --profile ../profiles/car.lua planet-latest.osm.pbf

Using Multiple Profiles with the Same Input ​

You can extract the same OSM file with different profiles by specifying an output path:

bash
osrm-extract --profile profiles/car.lua planet.osm.pbf --output /data/car
+osrm-extract --profile profiles/bicycle.lua planet.osm.pbf --output /data/bicycle
+osrm-extract --profile profiles/foot.lua planet.osm.pbf --output /data/foot

This avoids the need to create symbolic links to the input file.

Processing flow ​

It's important to understand that profiles are used when preprocessing the OSM data, NOT at query time when routes are computed.

This means that after modifying a profile you will need to extract, contract and reload the data again and to see changes in the routing results. See Processing Flow for more.

Profiles are written in Lua ​

Profiles are not just configuration files. They are scripts written in the Lua scripting language. The reason for this is that OpenStreetMap data is complex, and it's not possible to simply define tag mappings. Lua scripting offers a powerful way to handle all the possible tag combinations found in OpenStreetMap nodes and ways.

Basic structure of profiles ​

A profile will process every node and way in the OSM input data to determine what ways are routable in which direction, at what speed, etc.

A profile will typically:

  • Define api version (required)
  • Require library files (optional)
  • Define setup function (required)
  • Define process functions (some are required)
  • Return functions table (required)

A profile can also define various local functions it needs.

Looking at car.lua as an example, at the top of the file the api version is defined and then required library files are included.

Then follows the setup function, which is called once when the profile is loaded. It returns a big hash table of configurations, specifying things like what speed to use for different way types. The configurations are used later in the various processing functions. Many adjustments can be done just by modifying this configuration table.

The setup function is also where you can do other setup, like loading an elevation data source if you want to consider that when processing ways.

Then come the process_node and process_way functions, which are called for each OSM node and way when extracting OpenStreetMap data with osrm-extract.

The process_turn function processes every possible turn in the network, and sets a penalty depending on the angle and turn of the movement.

Profiles can also define a process_segment function to handle differences in speed along an OSM way, for example to handle elevation. As you can see, this is not currently used in the car profile.

At the end of the file, a table is returned with references to the setup and processing functions the profile has defined.

Understanding speed, weight and rate ​

When computing a route from A to B there can be different measures of what is the best route. That's why there's a need for different profiles.

Because speeds vary on different types of roads, the shortest and the fastest route are typically different. But there are many other possible preferences. For example a user might prefer a bicycle route that follow parks or other green areas, even though both duration and distance are a bit longer.

To handle this, OSRM doesn't simply choose the ways with the highest speed. Instead it uses the concepts of weight and rate. The rate is an abstract measure that you can assign to ways as you like to make some ways preferable to others. Routing will prefer ways with high rate.

The weight of a way is normally computed as length / rate. The weight can be thought of as the resistance or cost when passing the way. Routing will prefer ways with low weight.

You can also set the weight of a way to a fixed value. In this case it's not calculated based on the length or rate, and the rate is ignored.

You should set the speed to your best estimate of the actual speed that will be used on a particular way. This will result in the best estimated travel times.

If you want to prefer certain ways due to other factors than the speed, adjust the rate accordingly. If you adjust the speed, the time estimation will be skewed.

If you set the same rate on all ways, the result will be shortest path routing. If you set rate = speed on all ways, the result will be fastest path routing. If you want to prioritize certain streets, increase the rate on these.

Elements ​

api_version ​

A profile should set api_version at the top of your profile. This is done to ensure that older profiles are still supported when the api changes. If api_version is not defined, 0 will be assumed. The current api version is 4.

Library files ​

The folder profiles/lib/ contains Lua library files for handling many common processing tasks.

FileNotes
way_handlers.luaFunctions for processing way tags
tags.luaFunctions for general parsing of OSM tags
set.luaDefines the Set helper for handling sets of values
sequence.luaDefines the Sequence helper for handling sequences of values
access.luaFunction for finding relevant access tags
destination.luaFunction for finding relevant destination tags
maxspeed.luaFunction for determining maximum speed
guidance.luaFunction for processing guidance attributes

They all return a table of functions when you use require to load them. You can either store this table and reference its functions later, or if you need only a single function you can store that directly.

setup() ​

The setup function is called once when the profile is loaded and must return a table of configurations. It's also where you can do other global setup, like loading data sources that are used during processing.

Note that processing of data is parallelized and several unconnected Lua interpreters will be running at the same time. The setup function will be called once for each. Each Lua interpreter will have its own set of globals.

The following global properties can be set under properties in the hash you return in the setup function:

AttributeTypeNotes
weight_nameStringName used in output for the routing weight property (default 'duration')
weight_precisionUnsignedDecimal precision of edge weights (default 1)
left_hand_drivingBooleanAre vehicles assumed to drive on the left? (used in guidance, default false)
use_turn_restrictionsBooleanAre turn restrictions followed? (default false)
continue_straight_at_waypointBooleanMust the route continue straight on at a via point, or are U-turns allowed? (default true)
max_speed_for_map_matchingFloatMaximum vehicle speed to be assumed in matching (in m/s)
max_turn_weightFloatMaximum turn penalty weight
force_split_edgesBooleanTrue value forces a split of forward and backward edges of extracted ways and guarantees that process_segment will be called for all segments (default false)

The following additional global properties can be set in the hash you return in the setup function:

AttributeTypeNotes
excludableSequence of SetsDetermines which class-combinations are supported by the exclude option at query time. E.g. Sequence{Set{"ferry", "motorway"}, Set{"motorway"}} will allow you to exclude ferries and motorways, or only motorways.
classesSequenceDetermines the allowed classes that can be referenced using {forward,backward}_classes on the way in the process_way function.
restrictionsSequenceDetermines which turn restrictions will be used for this profile.
suffix_listSetList of name suffixes needed for determining if "Highway 101 NW" the same road as "Highway 101 ES".
relation_typesSequenceDetermines which relations should be cached for processing in this profile. It contains relations types

process_node(profile, node, result, relations) ​

Process an OSM node to determine whether this node is an obstacle, if it can be passed at all and whether passing it incurs a delay.

ArgumentDescription
profileThe configuration table you returned in setup.
nodeThe input node to process (read-only).
resultThe output that you will modify.
relationsStorage of relations to access relations, where node is a member.

The following attributes can be set on result: (Note: for new code use the obstacle_map.

AttributeTypeNotes
barrierBooleanIs it an impassable barrier?
traffic_lightsBooleanIs it a traffic light (incurs delay in process_turn)?

Obstacle ​

A user type that represents an obstacle on the road or a place where you can turn around.

This may be a completely impassable obstacle like a barrier, a temporary obstacle like a traffic light or a stop sign, or an obstacle that just slows you down like a traffic_calming. The obstacle may be present in both directions or in one direction only.

This also represents a good turning point like a mini_roundabout, turning_loop, or turning_circle.

An object of this type is immutable once constructed.

lua
local obs = Obstacle.new(
+  obstacle_type.traffic_signals,
+  obstacle_direction.forward,
+  2.5,
+  0
+)
+assert(obs.duration == 2.5)
MemberModeTypeNotes
typeread-onlyobstacle_typeeg. obstacle_type.barrier

durationread-onlyfloatThe expected delay in seconds
weightread-onlyfloatThe weight

obstacle_type ​

An enum with the following keys:

Keys
none
barrier
traffic_signals
stop
give_way
crossing
traffic_calming
mini_roundabout
turning_loop
turning_circle
gate

obstacle_direction ​

An enum with the following keys:

Keys
none
forward
backward
both

obstacle_map ​

A global user type. It stores obstacles.

The canonical workflow is: to store obstacles in process_node() and retrieve them in process_turn().

Note: In the course of processing, between the process_node() stage and the process_turn() stage, the extractor switches from using OSM nodes to using internal nodes. Both types have different ids. You can only store OSM nodes and only retrieve internal nodes. This implies that, in process_node(), you cannot retrieve an obstacle you have just stored.

obstacle_map:add(node, obstacle) ​

Call this function inside process_node() to register an obstacle on a node. You can register as many different obstacles as you wish on any given node. It is your responsibility to register the same obstacle only once.

In a following step -- likely in process_turn() -- you can retrieve all obstacles registered at any given node. This function works with OSM nodes.

ArgumentTypeNotes
nodeOSMNodeThe same node as passed to process_node.
obstacleObstacleThe obstacle

Usage example:

lua
function process_node(profile, node, result, relations)
+  ...
+  obstacle_map:add(node,
+    Obstacle.new(
+      obstacle_type.traffic_signal,
+      obstacle_direction.forward,
+      2, 0))
+end

obstacle_map:any(from, to, type) ​

Return true if there are any obstacles at node to when coming from node from and having the type type.

You will likely call this function inside process_turn(). Note that this works only with internal nodes, not with OSM nodes.

lua
bool obstacle_map:any(to)
+bool obstacle_map:any(from, to)
+bool obstacle_map:any(from, to, type)
ArgumentTypeNotes
fromNodeThe leading node. Optional.
toNodeThe node with the obstacle.
typeobstacle_typeThe obstacle type. Defaults to all types. May be a bitwise-or combination of types.
returnsboolTrue if there are any obstacles satisfiying the given criteria.

Usage examples:

lua
function process_turn(profile, turn)
+  if obstacle_map:any(turn.via) then
+    ...
+  end
+  if obstacle_map:any(turn.from, turn.via, obstacle_type.traffic_signal) then
+    turn.duration = turn.duration + 2
+  end
+end

obstacle_map:get(from, to, type) ​

This function retrieves all registered obstacles at node to when coming from the node from and having the type type.

You will likely call this function inside process_turn(). Note that this works only with internal nodes, not with OSM nodes.

lua
obstacle_map:get(to)
+obstacle_map:get(from, to)
+obstacle_map:get(from, to, type)
ArgumentTypeNotes
fromNodeThe leading node. Optional.
toNodeThe node with the obstacle.
typeobstacle_typeThe obstacle type. Defaults to all types. May be a bitwise-or combination of types.
returnstableA table of Obstacles.

Usage examples:

lua
function process_turn(profile, turn)
+  for _, obs in pairs(obstacle_map:get(turn.via)) do
+    if obs.type == obstacle_type.barrier then
+      turn.duration = turn.duration + obs.duration
+    end
+  end
+  for _, obs in pairs(obstacle_map:get(
+      turn.from, turn.via, obstacle_type.traffic_signal)) do
+    turn.duration = turn.duration + obs.duration
+  end
+end

process_way(profile, way, result, relations) ​

Given an OpenStreetMap way, the process_way function will either return nothing (meaning we are not going to route over this way at all), or it will set up a result hash.

ArgumentDescription
profileThe configuration table you returned in setup.
wayThe input way to process (read-only).
resultThe output that you will modify.
relationsStorage of relations to access relations, where way is a member.

Importantly it will set result.forward_mode and result.backward_mode to indicate the travel mode in each direction, as well as set result.forward_speed and result.backward_speed to integer values representing the speed for traversing the way.

It will also set a number of other attributes on result.

Using the power of the scripting language you wouldn't typically see something as simple as a result.forward_speed = 20 line within the process_way function. Instead process_way will examine the tag set on the way, process this information in various ways, calling other local functions and referencing the configuration in profile, etc., before arriving at the result.

The following attributes can be set on the result in process_way:

AttributeTypeNotes
forward_speedFloatSpeed on this way in km/h. Mandatory.
backward_speedFloat""
forward_rateFloatRouting weight, expressed as meters/weight (e.g. for a fastest-route weighting, you would want this to be meters/second, so set it to forward_speed/3.6)
backward_rateFloat""
forward_modeEnumMode of travel (e.g. car, ferry). Mandatory. Defined in include/extractor/travel_mode.hpp.
backward_modeEnum""
forward_classesTableMark this way as being of a specific class, e.g. result.classes["toll"] = true. This will be exposed in the API as classes on each RouteStep.
backward_classesTable""
durationFloatAlternative setter for duration of the whole way in both directions
weightFloatAlternative setter for weight of the whole way in both directions
turn_lanes_forwardStringDirections for individual lanes (normalized OSM turn:lanes value)
turn_lanes_backwardString""
forward_restrictedBooleanIs this a restricted access road? (e.g. private, or deliveries only; used to enable high turn penalty, so that way is only chosen for start/end of route)
backward_restrictedBoolean""
is_startpointBooleanCan a journey start on this way? (e.g. ferry; if false, prevents snapping the start point to this way)
roundaboutBooleanIs this part of a roundabout?
circularBooleanIs this part of a non-roundabout circular junction?
nameStringName of the way
refStringRoad number (equal to set forward_ref and backward_ref with one value)
forward_refStringRoad number in forward way direction
backward_refStringRoad number in backward way direction
destinationsStringThe road's destinations

road_classification.motorway_classBooleanGuidance: way is a motorway
road_classification.link_classBooleanGuidance: way is a slip/link road
road_classification.road_priority_classEnumGuidance: order in priority list. Defined in include/extractor/road_classification.hpp
road_classification.may_be_ignoredBooleanGuidance: way is non-highway
road_classification.num_lanesUnsignedGuidance: total number of lanes in way

Way names ​

The WayHandlers.names function in way_handlers.lua handles extraction of way names for routing instructions. It processes the following OSM tags:

TagNotes
namePrimary name of the way
name:pronunciationPronunciation hint for text-to-speech
refRoad reference number (e.g., "A1", "I-95")
junction:refExit or junction reference number

For unnamed sidewalks and sidepaths (where highway=footway, highway=cycleway, or highway=path), the function also supports fallback name tags when the way is marked as a sidepath:

TagNotes
is_sidepath:of:nameName of the street the sidepath follows (checked first)
street:nameAlternative tag for the associated street name

The fallback is only applied when the way has one of these sidepath markers:

  • footway=sidewalk
  • cycleway=sidepath
  • is_sidepath=yes

This allows routing instructions to show street names for separately mapped sidewalks, e.g., "Turn right onto Main Street" instead of just "Turn right".

process_segment(profile, segment) ​

The process_segment function is called for every segment of OSM ways. A segment is a straight line between two OSM nodes.

An OpenStreetMap way cannot have different tags on different parts of a way. Instead you would split the way into several smaller ways. However, many ways are long. For example, many ways pass over hills without any change in tags.

Processing each segment of an OSM way makes it possible to have different speeds on different parts of a way based on external data like data about elevation, pollution, noise or scenic value and adjust weight and duration of the segment accordingly.

In the process_segment function you don't have access to OSM tags. Instead you use the geographical location of the start and end point of the way to look up information from another data source, like elevation data. See rasterbot.lua for an example.

The following attributes can be read and set on the result in process_segment:

AttributeRead/write?TypeNotes
source.lonReadFloatCo-ordinates of segment start
source.latReadFloat""
target.lonReadFloatCo-ordinates of segment end
target.latReadFloat""
distanceReadFloatLength of segment
weightRead/writeFloatRouting weight for this segment
durationRead/writeFloatDuration for this segment

process_turn(profile, turn) ​

The process_turn function is called for every possible turn in the network. Based on the angle and type of turn you assign the weight and duration of the movement.

The following attributes can be read and set on the result in process_turn:

AttributeRead/write?TypeNotes

Use these node IDs to retrieve obstacles. See: obstacle_map:get.

source_road, target_road, roads_on_the_right, and roads_on_the_left ​

The information of source_road, target_road, roads_on_the_right, and roads_on_the_left that can be read are as follows:

AttributeRead/write?TypeNotes
is_restrictedReadBooleanIs it a restricted access road? (See definition in process_way)

The order of the roads in roads_on_the_right and roads_on_the_left are counter clockwise. If the turn is a u turn, all other connected roads will be in roads_on_the_right.

Example

           c   e
+           |  /
+           | /
+    a ---- x ---- b
+          /|
+         / |
+        f  d

When turning from a to b via x,

  • roads_on_the_right[1] is the road xf
  • roads_on_the_right[2] is the road xd
  • roads_on_the_left[1] is the road xe
  • roads_on_the_left[2] is the road xc

Note that indices of arrays in Lua are 1-based.

highway_turn_classification and access_turn_classification ​

When setting appropriate turn weights and duration, information about the highway and access tags of roads that are involved in the turn are necessary. The Lua turn function process_turn does not have access to the original OSM tags anymore. However, highway_turn_classification and access_turn_classification can be set during setup. The classification set during setup can be later used in process_turn.

Example

In the following example we use highway_turn_classification to set the turn weight to 10 if the turn is on a highway and to 5 if the turn is on a primary.

function setup()
+  return {
+    highway_turn_classification = {
+      ['motorway'] = 2,
+      ['primary'] = 1
+    }
+  }
+end
+
+function process_turn(profile, turn) {
+  if turn.source_highway_turn_classification == 2 and turn.target_highway_turn_classification == 2 then
+    turn.weight = 10
+  end
+  if turn.source_highway_turn_classification == 1 and turn.target_highway_turn_classification == 1 then
+    turn.weight = 5
+  end
+}

Guidance ​

The guidance parameters in profiles are currently a work in progress. They can and will change. Please be aware of this when using guidance configuration possibilities.

Guidance uses road classes to decide on when/if to emit specific instructions and to discover which road is obvious when following a route. Classification uses three flags and a priority-category. The flags indicate whether a road is a motorway (required for on/off ramps), a link type (the ramps itself, if also a motorway) and whether a road may be omitted in considerations (is considered purely for connectivity). The priority-category influences the decision which road is considered the obvious choice and which roads can be seen as fork. Forks can be emitted between roads of similar priority category only. Obvious choices follow a major priority road, if the priority difference is large.

Using raster data ​

OSRM has built-in support for loading an interpolating raster data in ASCII format. This can be used e.g. for factoring in elevation when computing routes.

Use raster:load() in your setup function to load data and store the source in your configuration hash:

lua
function setup()
+  return {
+    raster_source = raster:load(
+      "rastersource.asc",  -- file to load
+      0,    -- longitude min
+      0.1,  -- longitude max
+      0,    -- latitude min
+      0.1,  -- latitude max
+      5,    -- number of rows
+      4     -- number of columns
+    )
+  }
+end

The input data must be an ASCII file with rows of integers, e.g.:

0  0  0   0
+0  0  0   250
+0  0  250 500
+0  0  0   250
+0  0  0   0

In your segment_function you can then access the raster source and use raster:query() to query to find the nearest data point, or raster:interpolate() to interpolate a value based on nearby data points.

You must check whether the result is valid before using it.

Example:

lua
function process_segment (profile, segment)
+  local sourceData = raster:query(profile.raster_source, segment.source.lon, segment.source.lat)
+  local targetData = raster:query(profile.raster_source, segment.target.lon, segment.target.lat)
+
+  local invalid = sourceData.invalid_data()
+  if sourceData.datum ~= invalid and targetData.datum ~= invalid then
+      -- use values to adjust weight and duration
+    [...]
+end

See rasterbot.lua and rasterbotinterp.lua for examples.

Helper functions ​

There are a few helper functions defined in the global scope that profiles can use:

  • durationIsValid
  • parseDuration
  • trimLaneString
  • applyAccessTokens
  • canonicalizeStringList

Python API ​

The Python bindings provide access to OSRM's routing services through the osrm package. Install with pip install osrm-bindings.

OSRM ​

The OSRM class is the main entry point. It requires a .osrm.* dataset prepared by the OSRM toolchain.

python
import osrm
+
+# From file
+engine = osrm.OSRM("path/to/data.osrm")
+
+# With keyword arguments

Python Bindings Development Guide ​

Installing for production ​

Pre-built wheels are published to PyPI for Linux (x86_64), macOS (x86_64), and Windows (amd64). They use the CPython 3.12 stable ABI (cp312-abi3) and therefore install on Python 3.12+:

bash
pip install osrm-bindings

The package itself supports Python 3.10+ when built from source — needed for 3.10/3.11, aarch64 Linux, arm64 macOS, or any platform without a pre-built wheel:

bash
pip install osrm-bindings --no-binary osrm-bindings

Source builds compile the full OSRM C++ library — this takes a long time. See platform-specific notes for prerequisites.

Installing for development ​

Clone the repo and install in editable mode with dev dependencies:

bash
git clone https://github.com/Project-OSRM/osrm-backend
+cd osrm-backend
+pip install -e ".[dev]"

Install pre-commit hooks:

bash
pre-commit install

Platform-specific build requirements ​

Linux ​

CI wheel builds run inside a custom manylinux image (nilsnolde/manylinux, branch osrm_python) that ships vcpkg pre-bootstrapped at the SHA pinned in vcpkg-configuration.json, plus a pre-warmed vcpkg binary cache compiled against this repo's vcpkg.json. The wheel build's own vcpkg install hits that cache instead of recompiling boost/tbb/etc. from source.

The image needs rebuilding when this repo's vcpkg.json, the baseline SHA in vcpkg-configuration.json, or any file under vcpkg-overlay-ports/ changes — otherwise the wheel build either misses the cache (slow) or fails on a missing port. The manylinux repo's Build workflow takes an osrmRef input for that purpose; see its README.

For local source builds outside the manylinux image, install vcpkg yourself, point CMake at its toolchain, and use the release-only triplet to match the cache:

bash
git clone https://github.com/microsoft/vcpkg
+./vcpkg/bootstrap-vcpkg.sh
+export VCPKG_ROOT=$PWD/vcpkg
+export CMAKE_ARGS="-DCMAKE_TOOLCHAIN_FILE=$VCPKG_ROOT/scripts/buildsystems/vcpkg.cmake -DVCPKG_TARGET_TRIPLET=x64-linux-release"

macOS ​

Install OSRM's C++ dependencies via Homebrew (the same set the cibuildwheel macOS before-all uses; all ship CMake config files so the find_package(... CONFIG REQUIRED) calls in CMakeLists.txt resolve without a toolchain file):

bash
brew install lua tbb boost@1.90 fmt rapidjson sol2 flatbuffers \
+             protozero libosmium
+brew link boost@1.90

Windows ​

Windows uses vcpkg in manifest mode for OSRM's C++ dependencies. Clone and bootstrap it, then export VCPKG_ROOT:

powershell
git clone https://github.com/microsoft/vcpkg
+.\vcpkg\bootstrap-vcpkg.bat
+$env:VCPKG_ROOT = "$PWD\vcpkg"

Pass the toolchain to CMake at build time via CMAKE_ARGS (see below).

Building locally ​

A standard pip install -e . works, but by default pip uses PEP 517 isolated builds — each invocation creates a temporary directory, compiles everything, then discards it. This means OSRM is recompiled from scratch every time.

Use --no-build-isolation to make scikit-build-core reuse the persistent build directory (build/{wheel_tag}/) across runs:

bash
# Linux / macOS
+pip install -e . --no-build-isolation
+
+# Windows (PowerShell) — VCPKG_ROOT must be set, see Platform-specific
+# build requirements
+$env:CMAKE_ARGS = "-DCMAKE_TOOLCHAIN_FILE=$env:VCPKG_ROOT\scripts\buildsystems\vcpkg.cmake -DVCPKG_TARGET_TRIPLET=x64-windows-static-md"
+pip install -e . --no-build-isolation

The first run is slow (full OSRM compile). Subsequent runs only recompile changed binding files.

Keep config flags identical across runs

scikit-build-core hashes its configuration to detect changes. If the flags differ between runs, it wipes the build directory and starts from scratch.

Generator mismatch

CMake records the generator in CMakeCache.txt. If you ever see Does not match the generator used previously, delete the build directory and rebuild from scratch:

powershell
Remove-Item -Recurse -Force build/cp312-abi3-win_amd64

Building a wheel ​

After the editable install has compiled everything, produce a wheel without recompiling:

bash
# Linux / macOS
+pip wheel . --no-build-isolation -w dist
+
+# Windows (PowerShell) — uses the same CMAKE_ARGS as the editable install above
+pip wheel . --no-build-isolation -w dist

CMake finds the existing artifacts in the build directory and skips recompilation. The wheel lands in dist/.

Wheel repair ​

Locally built wheels link against system shared libraries and are tagged as linux_x86_64 (not manylinux). To make them portable or to inspect their dependencies, use the platform-specific repair tools:

Linux — auditwheel:

bash
pip install auditwheel
+auditwheel show dist/*.whl          # inspect shared library dependencies
+auditwheel repair -w dist dist/*.whl # bundle libs and retag as manylinux

macOS — delocate:

bash
pip install delocate
+delocate-listdeps dist/*.whl        # inspect dependencies
+delocate-wheel -w dist dist/*.whl   # bundle dylibs

Windows — delvewheel:

bash
pip install delvewheel
+delvewheel show dist/*.whl          # inspect dependencies
+delvewheel repair -w dist dist/*.whl

On Windows, vcpkg's shared DLLs (tbb12.dll, hwloc.dll — TBB is shared even under the static-md triplet) live in build\<wheel-tag>\vcpkg_installed\x64-windows-static-md\bin\. Pass that to delvewheel via --add-path so it can resolve and bundle them:

powershell
delvewheel repair --analyze-existing-exes `
+    --add-path build\cp312-abi3-win_amd64\vcpkg_installed\x64-windows-static-md\bin `
+    --add-dll hwloc.dll --no-mangle tbb12.dll --no-mangle hwloc.dll `
+    -w dist dist\*.whl

TIP

cibuildwheel runs wheel repair automatically in CI. You only need these commands when building wheels locally for distribution.

Compiler cache ​

On Linux and macOS, ccache is used automatically (pre-installed in the manylinux image; installed via Homebrew for macOS CI).

On Windows, scikit-build-core defaults to the Visual Studio generator, which does not support CMAKE_CXX_COMPILER_LAUNCHER. The build dir reuse from --no-build-isolation is the main speed optimisation for local Windows development.

Running tests ​

Build the test data (requires the package to be installed so the osrm executables are available):

bash
# Linux / macOS
+cd test/data && make
+
+# Windows
+cd test\data && windows-build-test-data.bat

Load the shared memory datastore:

bash
python -m osrm datastore test/data/ch/monaco

Run the test suite:

bash
pytest test/python/

Running cibuildwheel locally ​

cibuildwheel builds wheels inside isolated environments that closely match CI. Install it with:

bash
pip install cibuildwheel

Build for the current platform:

bash
cibuildwheel --platform linux    # requires Docker on non-Linux hosts
+cibuildwheel --platform macos
+cibuildwheel --platform windows

Wheels land in wheelhouse/.

Windows note: the toolchain wiring (CMAKE_TOOLCHAIN_FILE, VCPKG_TARGET_TRIPLET) lives in [tool.cibuildwheel.windows].environment in pyproject.toml, where $VCPKG_ROOT is expanded at build time from the host environment. Make sure VCPKG_ROOT is set in your shell before invoking cibuildwheel.

Linux note: the wheel build inside the manylinux container reads VCPKG_ROOT and VCPKG_DEFAULT_BINARY_CACHE from the image's ENV, so no toolchain forwarding is needed from the host. If you override CIBW_ENVIRONMENT_LINUX to mount a host ccache, remember it replaces (not merges with) [tool.cibuildwheel.linux].environment in pyproject.toml — re-include LD_LIBRARY_PATH and the CMAKE_ARGS line verbatim:

bash
CIBW_CONTAINER_ENGINE="docker; create_args: --volume /tmp/ccache:/ccache" \
+CIBW_ENVIRONMENT_LINUX='LD_LIBRARY_PATH=/usr/local/lib64:${LD_LIBRARY_PATH} CCACHE_DIR=/ccache CMAKE_ARGS="-DCMAKE_TOOLCHAIN_FILE=$VCPKG_ROOT/scripts/buildsystems/vcpkg.cmake -DVCPKG_TARGET_TRIPLET=x64-linux-release"' \
+cibuildwheel --platform linux

Type stubs ​

src/python/osrm/osrm_ext.pyi is auto-generated by nanobind_add_stub() at build time and committed to the repository so documentation tools can work without compiling the extension.

After changing C++ bindings, rebuild and commit the updated stub:

bash
pip install -e . --no-build-isolation   # regenerates the .pyi
+git add src/python/osrm/osrm_ext.pyi

To regenerate manually without a full rebuild:

bash
pip install nanobind ruff
+python -m nanobind.stubgen -m osrm.osrm_ext -o src/python/osrm/osrm_ext.pyi
+ruff format src/python/osrm/osrm_ext.pyi

Releasing ​

Releases are driven by the monthly release workflow (.github/workflows/release-monthly.yml), not by pushing a tag by hand. The workflow bumps the version, creates the tag, drives CI, downloads the built wheels, and publishes to both PyPI and npm in one shot.

Scheduled monthly release ​

A cron on the 1st of each month at 08:00 UTC runs the workflow against master:

  1. Compute the next version as (YYYY-2000).M.patchlevel (e.g. 26.4.0).
  2. Bump package.json + package-lock.json, commit, create annotated tag v<version>, push branch and tag.
  3. Dispatch osrm-backend.yml on the tag. That run builds wheels + sdist via cibuildwheel and uploads them as wheels-* artifacts.
  4. Wait for the dispatched CI run to finish with conclusion success.
  5. Run the publish job: download every wheels-* artifact into dist/, publish to PyPI via trusted publisher (OIDC), then npm publish.

If PyPI fails, the npm publish still runs (the npm steps have if: ${{ !cancelled() }}), and the overall job is marked failed so the PyPI problem stays visible.

Manual release ​

Trigger the workflow from the Actions UI or gh workflow run release-monthly.yml with optional inputs:

  • version_override — set the version explicitly (e.g. 26.4.1) instead of using the (YYYY-2000).M.patchlevel calculation.
  • branch — release from a branch other than master.

Verification ​

After the run finishes, check:

Version mechanics ​

pyproject.toml uses setuptools-scm with local_scheme = "no-local-version". On a tag checkout (e.g. v26.4.0), the Python version resolves cleanly to 26.4.0, matching the package.json version that release-monthly.yml committed when creating the tag.

Releasing a new OSRM version ​

We use a unified semver versioning scheme for monthly releases: (YYYY-2000).M.patchlevel

  • Format: X.M.patchlevel where X = year - 2000, M = month (1-12, no leading zeros)
  • Example: 26.4.0 represents April 2026, first release
  • Git tags: Prefixed with v (e.g., v26.4.0)
  • npm packages: Unprefixed semver (e.g., 26.4.0)

Version History ​

Previous scheme (ended 2025): Traditional semantic versioning (v6.0, v6.0.1, v6.0.2, etc.)

  • Last release: v6.0.0 in December 2025
  • Manual release process

New scheme (started 2026): Monthly date-based versioning with automated releases

  • First release: v26.1.0 (January 2026)
  • Automatic monthly releases on the 1st of each month at 08:00 UTC
  • Year offset: 2026 → 26, 2027 → 27, etc.
  • Month: 1-12 (no leading zeros), patch: 0-N per month

Versioning Scheme ​

Format ​

Git tags: vX.M.patchlevel where X = year - 2000, M = 1-12

  • X: Year offset (26 = 2026, 27 = 2027, etc.)
  • M: Month (1-12, no leading zeros)
  • patchlevel: Incremental counter starting at 0 per month (0, 1, 2, ...)

npm packages: X.M.patchlevel (same as git tag without the v prefix)

Examples ​

Git tags and npm versions for the same release:

  • April 2026, 1st release: Git tag v26.4.0, npm 26.4.0
  • April 2026, 2nd release: Git tag v26.4.1, npm 26.4.1
  • May 2026, 1st release: Git tag v26.5.0, npm 26.5.0
  • January 2027, 1st release: Git tag v27.1.0, npm 27.1.0

Release Compatibility Guarantees ​

Patch version change (new patchlevel in same month) ​

  • No change of query parameters or response formats
  • Compatible HTTP API
  • Compatible C++ library API
  • Compatible node-osrm API
  • Compatible OSRM datasets

Month change (new YYYY-MM) ​

  • May introduce forward-compatible changes: query parameters and response properties may be added in responses, but existing properties may not be changed or removed
  • Forward-compatible HTTP API
  • Forward-compatible C++ library API
  • Forward-compatible node-osrm API
  • No compatibility between OSRM datasets (needs new processing)

Conventional Commits ​

Pull request titles must follow Conventional Commits format with types: feat, fix, docs, style, refactor, perf, test, ci, chore, build. This is validated in CI and helps organize the commit history.

Breaking changes should be indicated with the ! suffix in the PR title (e.g., feat!: remove deprecated API) so they are called out in release notes.

Release Management ​

  • The master branch is for development and should always be green
  • Automated monthly releases occur on the 1st of each month at 08:00 UTC
  • All changes in master will be automatically released monthly
  • No release candidates are used; the master branch is the quality gate
  • Patch versions within the same month can be released manually at any time

Automated Release Process ​

Releases are created automatically every month on a scheduled basis:

  1. A GitHub Actions workflow runs on the 1st of each month at 08:00 UTC
  2. Version is calculated as (YYYY-2000).M.patchlevel with M = 1-12 (no leading zeros)
  3. package.json and package-lock.json versions are updated
  4. A git tag is created and pushed (e.g., v26.4.0)
  5. A GitHub Release is published with auto-generated release notes
  6. The package is published to npm (format: 26.4.0 without v prefix)

Manual Release Trigger ​

You can also trigger a release manually on any branch:

  1. Go to Actions → Monthly Release workflow
  2. Click Run workflow
  3. Select your branch (defaults to master)
  4. Optionally override the version (format: X.M.patchlevel with M = 1-12, e.g., 26.4.0)
  5. Click Run workflow

This is useful for:

  • Out-of-schedule patch releases within the same month
  • Emergency releases from other branches
  • Backports to older versions

Release Checklist ​

When releasing (automated or manual):

  1. ✅ All GitHub Actions CI checks pass
  2. ✅ The target branch is in a releasable state
  3. ✅ For manual releases: verify the version format is correct (X.M.patchlevel with month 1-12, e.g., 26.4.0)
  4. ✅ The release is created automatically with:
    • Git tag
    • GitHub Release (with auto-generated release notes)
    • npm publication

After Release ​

No additional manual steps are required. The automated workflow handles:

  • Version bumping in package.json
  • Git commit and tag creation
  • GitHub Release publishing
  • npm package publication

For non-automated releases, monitor:

  • GitHub Actions to verify the release completed successfully
  • npm registry to confirm the new version is published

Environment Variables ​

SHM_LOCK_DIR ​

If the SHM_LOCK_DIR environment variable is set, OSRM will use it as the directory for shared memory lock files instead of the system temporary directory. This is useful in containerized environments (Docker/Kubernetes) where the lock file directory should persist across container restarts when loading from shared memory.

SIGNAL_PARENT_WHEN_READY ​

If the SIGNAL_PARENT_WHEN_READY environment variable is set osrm-routed will send the USR1 signal to its parent when it will be running and waiting for requests. This could be used to upgrade osrm-routed to a new binary on the fly without any service downtime - no incoming requests will be lost.

DISABLE_ACCESS_LOGGING ​

If the DISABLE_ACCESS_LOGGING environment variable is set osrm-routed will not log any http requests to standard output. This can be useful in high traffic setup.

Testsuite ​

OSRM comes with a testsuite containing both unit-tests using the Boost library and cucumber.js for scenario driven testing.

Unit Tests ​

For a general introduction on Boost.Test have a look at its docs.

Separate Test Binaries ​

Unit tests should be registered according to the sub-project they're in. If you want to write tests for utility functions, add them to the utility test binary. See CMakeLists.txt in the unit test directory for how to register new unit tests.

Using Boost.Test Primitives ​

There is a difference between only reporting a failed condition and aborting the test right at a failed condition. Have a look at BOOST_CHECK vs BOOST_REQUIRE. Instead of manually checking e.g. for equality, less than, if a function throws etc. use their corresponding Boost.Test primitives.

If you use BOOST_CHECK_EQUAL you have to implement operator<< for your type so that Boost.Test can print mismatches. If you do not want to do this, define BOOST_TEST_DONT_PRINT_LOG_VALUE (and undef it after the check call) or sidestep it with BOOST_CHECK(fst == snd);.

Test Fixture ​

If you need to test features on a real dataset (think about this twice: prefer cucumber and dataset-independent tests for their reproducibility and minimality), there is a fixed dataset in test/data. This dataset is a small extract and may not even contain all tags or edge cases. Furthermore this dataset is not in sync with what you see in up-to-date OSM maps or on the demo server. See the library tests for how to add new dataset dependent tests.

To prepare the test data simply cd test/data/ and then run make.

Running Tests ​

To build the unit tests:

cd build
+cmake ..
+make tests

You should see the compiled binaries in build/unit_tests, you can then run each suite individually:

./engine-tests

Cucumber ​

For a general introduction on cucumber in our testsuite, have a look at the wiki.

This documentation aims to supply a guideline on how to write cucumber tests that test new features introduced into osrm.

Test the feature ​

It is often tempting to reduce the test to a path and accompanying instructions. Instructions can and will change over the course of improving guidance.

Instructions should only be used when writing a feature located in features/guidance. All other features should avoid using instructions at all.

Write Tests to Scale ​

OSRM is a navigation engine. Tests should always consider this context.

An important implication is the grid size. If tests use a very small grid size, you run into the chance of instructions being omitted. For example:

Background:
+    Given the profile "car"
+    Given a grid size of 10 meters
+
+Scenario: Testbot - Straight Road
+    Given the node map
+        """
+        a b c d
+        """
+
+    And the ways
+        | nodes | highway |
+        | ab    | primary |
+        | bc    | primary |
+        | cd    | primary |
+
+    When I route I should get
+        | from | to | route       |
+        | a    | d  | ab,bc,cd,cd |

In a navigation engine, the instructions

  • depart east on ab
  • in 10 meters the road name changes to bc
  • in 10 meters the road name changes to cd
  • you arrived at cd

would be impossible to announce and not helpful at all. Since no actual choices exist, the route you get could result in ab,cd and simply say depart and arrive.

To prevent such surprises, always consider the availability of other roads and use grid sizes/road lengths that correspond to actually reasonable scenarios in a road network.

Use names ​

If you specify many nodes in close succession to present a specific road geometry, consider using name to indicate to OSRM that the segment is a single road.

Background:
+    Given the profile "car"
+    Given a grid size of 10 meters
+
+Scenario: Testbot - Straight Road
+    Given the node map
+        """
+        a b c d
+        """
+
+    And the ways
+        | nodes | highway | name |
+        | ab    | primary | road |
+        | bc    | primary | road |
+        | cd    | primary | road |
+
+    When I route I should get
+        | from | to | route     | turns         |
+        | a    | d  | road,road | depart,arrive |

Guidance guarantees only essential maneuvers. You will always see depart and arrive as well as all turns that are not obvious.

So the following scenario does not change the instructions

Background:
+    Given the profile "car"
+    Given a grid size of 10 meters
+
+Scenario: Testbot - Straight Road
+    Given the node map
+        """
+        a b
+        d c
+        """
+
+    And the ways
+        | nodes | highway | name |
+        | ab    | primary | road |
+        | bc    | primary | road |
+        | cd    | primary | road |
+
+    When I route I should get
+        | from | to | route     | turns         |
+        | a    | d  | road,road | depart,arrive |

but if we modify it to

Background:
+    Given the profile "car"
+    Given a grid size of 10 meters
+
+Scenario: Testbot - Straight Road
+    Given the node map
+        """
+        a b e
+        d c
+        """
+
+    And the ways
+        | nodes | highway | name |
+        | ab    | primary | road |
+        | bc    | primary | road |
+        | cd    | primary | road |
+        | be    | primary | turn |
+
+    When I route I should get
+        | from | to | route          | turns                        |
+        | a    | d  | road,road,road | depart,continue right,arrive |

Test all directions ​

Modelling a road as roundabout has an implied oneway tag associated with it. In the following case, we can route from a to d but not from d to a. To discover those errors, make sure to check for all allowed directions.

Scenario: Enter and Exit mini roundabout with sharp angle   # features/guidance/mini-roundabout.feature:37
+    Given the profile "car"                                   # features/step_definitions/data.js:8

+        a b
+          c d
+        """
+    And the ways                                              # features/step_definitions/data.js:128

Prevent Randomness ​

Some features in OSRM can result in strange experiences during testcases. To prevent some of these issues, follow the guidelines below.

Use Waypoints ​

Using grid nodes as waypoints offers the chance of unwanted side effects. OSRM converts the grid into a so called edge-based graph.

Scenario: Testbot - Intersection
+    Given the node map
+        """
+          e
+        b a d
+          c
+        """
+
+    And the ways
+        | nodes | highway | oneway |
+        | ab    | primary | yes    |
+        | ac    | primary | yes    |
+        | ad    | primary | yes    |
+        | ae    | primary | yes    |

Selecting a as a waypoint results in four possible starting locations. Which one of the routes a,b, a,c, a,d, or a,e is found is pure chance and depends on the order in the static r-tree.

To guarantee discovery, use:

Scenario: Testbot - Intersection
+    Given the node map
+        """
+            e
+            4
+        b 1 a 3 d
+            2
+            c
+        """
+
+    And the ways
+        | nodes | highway | oneway |
+        | ab    | primary | yes    |
+        | ac    | primary | yes    |
+        | ad    | primary | yes    |
+        | ae    | primary | yes    |

And use 1,2,3, and 4 as starting waypoints. The routes 1,b, 2,c, 3,d, and 4,e can all be discovered.

Allow For Small Offsets ​

Whenever you are independent of the start location (see use waypoints), the waypoint chosen as start/end location can still influence distances/durations.

If you are testing for a duration metric, allow for a tiny offset to ensure a passing test in the presence of rounding/snapping issues.

Don't Rely on Alternatives ​

Alternative route discovery is a random feature in itself. The discovery of routes depends on the contraction order of roads and cannot be assumed successful, ever.

Understanding Turn Restrictions ​

Adding turn restrictions requires the restriction to follow a very specific format.

We specify them in a table with the header | type | way:from | way:to | node:via | restriction |. It is important that turn restrictions require micro segmentation.

Consider the following scenario:

Given the node map:
+    """
+          e
+          |
+    a - - b - - c
+          |
+          d
+    """
+
+And the ways
+    | nodes | oneway |
+    | abc   | yes    |
+    | ebd   | yes    |
+
+And the relations
+    | type        | way:from | way:to | node:via | restriction   |
+    | restriction | abc      | ebd    | b        | no_right_turn |

The setting looks perfectly fine at first glance. However, it is not well defined. The forbidden right turn could be either a superfluous addition, forbidding the turn cb to be, or actually refer to the turn ab to bd to say that a turn is forbidden here.

To model turn-restrictions correctly and uniquely, we need to split segments that contribute to the restriction into the smallest possible parts. E.g. the above scenario could correctly be expressed as:

Given the node map:
+    """
+          e
+          |
+    a - - b - - c
+          |
+          d
+    """
+
+And the ways
+    | nodes | oneway | name |
+    | ab    | yes    | abc  |
+    | bc    | yes    | abc  |
+    | eb    | yes    | ebd  |
+    | bd    | yes    | ebd  |
+
+And the relations
+    | type        | way:from | way:to | node:via | restriction   |
+    | restriction | ab       | bd     | b        | no_right_turn |

Unless this format is used, OSRM will omit the (then ambiguous) turn restrictions and ignore them.

My Guidance Tests are Failing - Understanding what you can change ​

If you change some stuff in guidance, you will easily see tests change their result. E.g. if you change the angles for which we report right, then obviously some tests might not report a direction modifier named right anymore.

This small section will try to guide you in making the correct decisions for changing the behaviour of tests.

The difficulty in guidance tests is that not all items can be translated 1:1 from the ascii art into turn-angles.

The turn-angle calculation tries to find turn angles that would represent perceived turn angles, not the exact angle at the connection.

This is necessary, since connections in OSM are always bound by the paradigm that the way is supposed to be in the middle of the actual road. For broad streets, you will see stronger angles than the actual turns.

Don't change the test, change the expected behaviour ​

If we have a test that looks like this:

Given a grid size of 5 m
+Given the node map
+"""
+a - b - - - - - - c
+     \  
+      d - - - - - e
+"""
+
+When I route I should get
+ | waypoints | route       | turns                          |
+ | a,e       | abc,bde,bde | depart,turn slight right,arrive|

And the test reports turn right for the route a->e, where before it said slight right.

If you change the turn angles, obviously you can expect changes in the distinction between slight right and right. In such a case it is, of course, reasonable to change the expected route to report right instead of slight right. You should consider inspecting the actual turn angles at b to see if you feel that change is justified.

However, you should never adjust the test itself. If you look at a failure, the other way around

Given a grid size of 5 m
+Given the node map
+"""
+a - b - - - - - - c
+     \  
+      d - - - - - e
+"""
+
+When I route I should get
+ | waypoints | route       | turns                   |
+ | a,e       | abc,bde,bde | depart,turn right,arrive|

where we see a slight right, over the expected right. We could be tempted to adjust the grid size (e.g. from 10 m to 20 meters).

Such a change would fundamentally alter the tests, though. Since the part b-d is a short offset, when we are looking at a grid of size 5 m, the angle calculation will try and compensate for this offset.

In this case we would see a very slight turn angle. If your change now reports different turn angles, you can of course change the expected result. But you should not adjust the grid size. The test would be testing turn angles of 180 and 100 degrees, instead of 180 and 160.

Consider Post-Processing Impacts ​

Some changes you might see could look completely unrelated. To understand the impact of your changes, you can make use of the debugging utilities you can find in util/debug.hpp (and potentially other related headers).

If your test is inspecting a series of turns (remember, a turn does not necessarily equals an instruction), you could see interaction with post-processing. To see the unprocessed turns, you should print the steps at the end of step assembly (assembleSteps in engine/guidance/assemble_steps.hpp).

If you see unexpected changes, you can consider adding the locations field to your test to study what location a turn is reported at.

To study a test without post-processing impacts, you can create a copy of the case on a very large grid (like 2000 meters). In such a grid, turn collapsing would be essentially disabled.

Sadly, there is no general guideline.

Use Caution ​

If in doubt, ask another person. Inspect as much of the data as possible (e.g. print un-collapsed steps, turn angles and so on) and use your best judgement, if the new result seems justified.

Building OSRM for Windows ​

There is experimental support for building OSRM on Windows.

Dependencies ​

You will need a modern Windows development stack (e.g. Visual Studio 17). The published binaries are built with Windows Server 2025 Github hosted runners.

Dependencies are managed via vcpkg in manifest mode (see vcpkg.json at the repo root). The baseline commit is pinned in vcpkg-configuration.json.

Prerequisites ​

  1. Install Visual Studio 2022 with the "Desktop development with C++" workload.
  2. Clone vcpkg and bootstrap it:
bat
git clone https://github.com/microsoft/vcpkg.git C:\vcpkg
+C:\vcpkg\bootstrap-vcpkg.bat
+set VCPKG_ROOT=C:\vcpkg

Building ​

From a x64 Native Tools Command Prompt for VS 2022 at the repo root:

bat
cmake --preset ci-windows -DENABLE_NODE_BINDINGS=ON
+cmake --build --preset ci-windows

The first configure will build every dependency from source, which takes a while. Subsequent configures reuse vcpkg's binary cache.
