Data model

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

Genealogy

This dataset represents the routes of regular commercial bus routes. The "commercial line" describes the line as perceived on the ground by the traveler. Managed internally by Ile-de-France Mobilités, it is attached to an "administrative line" (linked to an operating contract) which includes one to several commercial lines. Attributes are used to link to the referential of lines (https://prim.iledefrance-mobilites.fr/fr/jeux-de-donnees/referentiel-des-lignes)These routes follow the road network.

The updating of the lines is carried out gradually:

  • Rows for which no offer changes were detected have been retained. These are based on the BD TOPO IGN (BD Topo®) road referential.
  • The lines whose offer has been modified have been recalculated automatically (without manual resumption) on the Open Street Map road referential (© OpenStreetMap contributors).


Quality

The value date of the object makes it possible to understand the validity of the proposed line route. It should be noted that a discrepancy between the data and the field can be observed.
