GTFS Extensions

Both GTFS Sverige 2 and GTFS Regional uses some of the GTFS Extensions. These extensions are not part of the specification, but are additions to offer additional details.

Extended Route Types

Extended route types allow for more specific transport modes to be used. GTFS Sverige and GTFS Regional does not use the standard one digit GTFS route types, but only uses extended route types.

The following list shows the most used transport modes for GTFS Sverige and GTFS Regional. This is a non-extensive list, only meant to give an idea of the types you should support. You should still be able to handle the other types in a graceful way, as new traffic may make use of them without prior warning.

Trip-to-trip transfers

GTFS Sverige 2 and GTFS Regional includes trip-to-trip transfers, which are detailed transfer rules that provide additional details on which transfers are possible, and how long they take.

Trip-to-trip transfers used to be an extension to the GTFS standard, but this extension has been formally adopted into the GTFS standard in October 2021.

Trip to trip transfers make use of the from_trip_id and to_trip_id columns in the transfers.txt file.

From Googles documentation: The from_trip_id and to_trip_id fields can contain a trip_id, as specified by trips.txt. If from_trip_id is specified, the transfer will only apply to the arriving trip with the given trip id, at the given from_stop_id. If to_trip_id is specified, the transfer will only apply to the departing trip with the given trip id, at the given to_stop_id.
