What is in the repository

services/planning: the Planner (Python): data pipelines, access analysis, gap index, demand model, zone suggestion, scenario compare, calibration.
packages/dispatch: the dispatch and pooling engine, with a property-based test that no service constraint is ever violated.
packages/funding: the cost model, funding-stack engine and double-entry ledger, with a test that forbids per-ride commissions.
packages/gtfs: GTFS, GTFS-Flex, GTFS Realtime and NTD-style exports.
apps/*: the public site, agency console, rider and driver apps, API and worker.
city-packs/: one folder per city. Add a city with pnpm opentransit city:new <slug>.

GTFS with GTFS-Flex (locations.geojson, booking_rules.txt) for zone-based service.
GTFS Realtime vehicle positions and trip updates.
National Transit Database (NTD)-style monthly summary for demand-response service (a preparation aid, not an official filing).
Anonymized trip files: trip ends coarsened to H3 resolution 8 and times to 15 minutes. The agency owns this data.
Planner outputs as GeoJSON and CSV with a methods note.

The REST API is described by an OpenAPI specification at api.opentransitlab.org/docs, so other agencies and vendors can integrate.
