Description
In Chouette, the user has the possibility to create codes using Macro lists in order to match his scheduled offer with his real-time offer in Ara SaaS. By using the identifiers to create these codes, stops, lines and vehicle journeys of the scheduled offer in GTFS can be matched with stops, lines and vehicle journeys of the real time offer in GTFS-RT.
