Where the data comes from
Timetables come from the GTFS datasets that French mobility authorities and operators publish on the national open transport data platform (transport.data.gouv.fr). Each network publishes its planned service there: routes, stops, trips and service calendars.
We fetch those datasets automatically every night and rebuild the service at each stop from the most recent version. When an operator additionally publishes a real-time feed (in GTFS-RT or SIRI format) we match it against the planned service to show the departures actually expected.
