Data model

Geographic layer describing the routes of regular commercial bus lines in Île-de-France, authorized to operate by Île-de-France Mobilités.


The "commercial line" describes the line as perceived on the ground by the passenger. In the internal management of Ile-de-France Mobilités, it is attached to an "administrative line" which encompasses one or more commercial lines. Attributes are used to make the link.
Lines are updated progressively. A discrepancy between the data and the field may be observed.


The value date of the object is used to determine the validity of the proposed route. OpenStreetMap's road repository is used to create the routes (© OpenStreetMap contributors).
