On a test with London data, this feature flag has resulted in the graph.obj file decreased from 10.0 GB to 2.3 GB with 3 walk transfers and 1 bike transfer, and the number of BIKE transfers has decreased from 9938935 to 1459294.

I took a look at the functionality. Can you take a look at how the carsAllowedStopMaxTransferDuration is implemented in https://github.com/opentripplanner/OpenTripPlanner/blob/dev-2.x/application/src/main/java/org/opentripplanner/standalone/config/buildconfig/TransferParametersMapper.java and change your implementation to use the build config

[VillePihlava]

The build config changes look good. I don't fully understand the realtime aspect of the PR. What kind of realtime updates exist at graph build time that are not in the normal timetables? @miklcct Could you write a short explanation of you use case/goal. It could be that you are trying to do something that is currently not possible.

[VillePihlava]

Looks good, just a couple comments related to documentation and functionality. I'll take a look at the tests at a later date.

[VillePihlava]

In addition to the previous feedback, I found a couple of things related to the tests. When all the changes have been done, I think this PR should be ready

[VillePihlava]

You should also add the field to this build config (similar to the line I linked) so that it automatically generates documentation:

OpenTripPlanner/application/src/test/resources/standalone/config/build-config.json

Line 89 in eff71e0

"carsAllowedStopMaxTransferDuration": "3h"

Looks good, I found a few things
