Data model

Set of files describing the transport offer (timetables, routes, lines, stops, connections between stops) planned over the next 30 days, for all public transport lines in the Ile-de-France region (OPTILE, RATP and SNCF). These files are updated 3 times a day. More precisely, at 8 a.m., 1 p.m. and 5 p.m.

The files bring together the offer of train, RER, metro, tram, bus and coach lines in the Ile-de-France region.


Genealogy of data

This data comes from each of the 75 public transport operators in the Paris region, which send Île-de-France Mobilités the scheduled schedules of their lines so that Île-de-France Mobilités can provide an information service to passengers (Ile-de-France Mobilités).

As part of its missions, Île-de-France Mobilités consolidates, aligns and controls the data that is transmitted by operators under the conditions set out in their operating contract. Île-de-France Mobilités then publishes them on its Ile-de-France Mobilités website and on its Open Data portal.

Île-de-France Mobilités and the operators regularly monitor the quality of the data.

Quality of files in GTFS format
  • The files describe the expected schedules over the next 30 days.
  • Information on access has been collected by Île-de-France Mobilités. This data is still imperfect and actions are underway with carriers to improve it. In the meantime, don't hesitate to help us by sending us your comments on [email protected]
  • The timetables of the SNCF lines include the adaptations made during planned works, as well as the substitutions made by bus (e.g. a bus journey will be offered if a section is cut off due to works).
  • The timetables of the RATP metro lines include adaptations made during planned works, as well as substitutions made by bus (e.g. a bus journey will be offered if a section is cut off due to works). The timetables of the other RATP lines (buses and trams) do not include adaptations made during planned works.
  • All RER A and B timetables are transmitted by the SNCF.
  • The GTFS format does not allow us to describe the Local Traffic Bans (ITL) that sometimes exist on some OPTILE bus lines.
