Description of Île-de-France Mobilités' GTFS
On the PRIM platform, Île-de-France Mobilités makes a GTFS (General Transit Feed Specification) available to data reusers, via the dataset "Scheduled timetables on Ile-de-France public transport lines (GTFS Datahub)". It is updated three times a day at 8am, 1pm and 5pm.
It is a set of files describing the theoretical transport offer in the next 30 days,proposed by all operators in the Île-de-France Region on all means of public transport (trains, RER, metros, streetcars, buses and coaches). In fact, the GTFS includesspatial data from the line and stop repository (stops, lines, directions, connections) and timetable files presenting the theoretical time of passage of a line at a specific stop.
Note that,the GTFS does not include real-time information. This set of files is based exclusively on the theoretical offer comunicated by carriers.
This data specification (GTFS) enables the transport organizing authority Île-de-France Mobilités to publish its transport data in a format that can be used by a large variety of software applications.
For more information about this data format, please feel free to consult this documentation.
Text files contained in the GTFS
In order to depict the theoretical transport offer over the next 30 days, the GTFS cross-references ten txt files, all of which you can download through the dataset export "Scheduled timetables on public transport lines in Ile-de-France (GTFS Datahub)" available on PRIM.
The ten files are organized as follows:
- The list of commercial transport networks "agency.txt"
- The lines of public transport"routes.txt"
- The stops and stations served as well as station/station access "stops_txt"
- The routesby line of transport "trips.txt"
- Theobject types (stop, stop zone, transfer zone, etc.) "stop_extensions.txt"
- The liaison on foot between two stops of a station/train station "pathways.txt"
- The dates and periods for running "calendar.txt"
- The exceptional dates for running "calendar_dates.txt"
- The scheduled stop times per line route "stop_times.txt"
- The walking connection times between nearby stops "transfers.txt"

A datavisualisation of the geographical components of the GTFS
The PRIM platform offers a visualization of the geographical data comprised by the GTFS (from the stop and line repositories). It is a map allowing you to display the lines and stops of the Ile-de-France network. Following is a screenshot of this map:
Feel free to consult this datavisualization in format "iframe" within the "Map" tab of the dataset "Scheduled timetables on public transport lines in Ile-de-France (GTFS Datahub)". In fact, the "iframe" format of the datavisualization allows you to parameterize it in order to display only the information that interests you. Please note that in order to access the datavisualization from the dataset's "Map" tab, you must imperatively be logged into your PRIM platform account. Otherwise, the map will not be displayed.
When setting up the datavisualization, you can choose to display only lines, only stops or both combined. You can also filter the display according to the network(Transilien, Noctilien, etc.), the types of transport (bus, train, metro, streetcar, etc.) and the operator that operates the line or serves the stop. Finally, it is also possible to display only one line and the stops it serves by using the search bar available within the datavisualization. To do this, simply select the first letter or number of the line you're looking for from the first drop-down list offered, then find it in the second drop-down list taking into account the parameter previously entered.
Clicking on a line opens a tooltip displaying: the identifier of this line in the GTFS of Île-de-France Mobilités, the network to which it belongs, the operator offering this transport offer and a link to the documentation available concerning this line.
Similarly, clicking on a specific stop on the map, displays the following information: the identifier of the stop in the Île-de-France Mobilités GTFS, its commune, the transport zone to which it belongs (from 1 to 5) and theaccessibility to the stop for wheelchair users.
