WA Transit Accessibility Dashboard

An interactive map dashboard showing bus route service frequencies and pedestrian/wheelchair walkshed accessibility for every city in Washington state.

Built with MapLibre GL JS. All pages are fully static — no backend server is required for end users.

What's in this repo

Maps

File / folder	Description
statewide.html	WA statewide overview — all bus routes colored by service frequency, with processed-city boundaries and stop dots
cities/index.html	Dashboard index — card grid of all ~250 WA jurisdictions with live pipeline status
cities/<slug>.html	Per-city map (e.g. cities/seattle.html) — routes, stops, pedestrian and wheelchair walkshed edges, and OSM amenity counts
seattle-routes.html	Master template that all city pages are generated from
yakima-routes.html	Standalone Yakima map (older prototype, kept for reference)
spokane-routes.html	Standalone Spokane map (older prototype, kept for reference)

Data files (in repo)

File / folder	Description
WA Bus Routes with score.csv	All WA bus routes with stop sequences and service-frequency columns
route_subsets/	Per-city subsets of the routes CSV (one file per processed city)
jurisdiction_bounds/	City and county boundary GeoJSON files (322 jurisdictions)
Jurisdiction Codes.csv	TDEI dataset IDs and versions for all WA jurisdictions
cities/jurisdictions.json	Metadata for all jurisdictions (display name, slug, type, version)
cities/processed_cities.json	Metadata for cities with completed walkshed data; used by the statewide map
pipeline_progress.json	Per-jurisdiction pipeline status tracking

Pipeline scripts

Script	What it does
run_city_pipeline.py	Runs the full 11-step pipeline for one city
batch_all_cities.py	Runs run_city_pipeline.py for every WA jurisdiction, resumably
regenerate_city_html.py	Rebuilds all city HTML pages from the template (no pipeline re-run needed)
build_index.py	Regenerates cities/index.html and cities/jurisdictions.json
run_walksheds_from_geojson.py	TDEI Walkshed API — generates reachable network from bus stop points
export_walkshed_edges_per_stop.py	Splits city-wide combined walkshed into one file per stop
query_osm_pois.py	Downloads OSM amenity data within the city's walkshed bounding box
count_amenities_in_walksheds.py	Counts reachable amenities per stop via spatial join

Utility / one-time scripts

These were used to build or augment the WA Bus Routes with score.csv file and are not part of the regular pipeline run:

add_access_score.py, add_essentials_columns.py, add_population_served.py, add_route_score.py, add_transit_score.py, build_jurisdiction_geojson.py, create_simplified_routes.py, fix_king_county_names.py, route_score_to_labels.py

Running locally

Browsers block fetch() of local files, so serve the repo over HTTP:

cd "path/to/HTML transit map"
npx serve .

Then open http://localhost:3000/cities for the dashboard, or http://localhost:3000/statewide.html for the statewide map.

City map pages load routes and stop dots immediately. The walkshed edges (shown when you click a stop) and amenity counts require the data/ folder, which is not in the repo — see QUICKSTART.md for how to generate it.

Generating walkshed data

See QUICKSTART.md for full step-by-step instructions covering:

• Running the pipeline for a single city
• Running the pipeline for all ~250 WA jurisdictions
• Regenerating HTML pages after template changes
• Required environment variables (TDEI credentials)

See DATA_FOLDER_GUIDE.md for a detailed description of every file and subfolder produced under data/<dataset_id>/.

Map features (per-city pages)

• Route lines — colored by each route's GTFS identity color
• Stop dots — green when the stop meets all selected frequency standards, grey otherwise
• Service-frequency filter — multi-select checkboxes: Weekday peak, Weekday midday, Weeknight, Weekend (AND logic)
• Pedestrian / wheelchair toggle — switches walkshed edges and amenity counts between profiles
• Click a stop — draws the walkshed network, shows reachable amenity counts by type, displays the stop's full 4-period service profile
• Click a route — shows per-period frequency bars (how many stops on that route meet each standard)
• City boundary overlay — low-opacity fill showing the jurisdiction extent

Map features (statewide page)

• All WA bus routes; same service-frequency filter (routes turn green when meeting all checked standards)
• Processed-city boundary overlays with clickable cards linking to full city maps
