Can my GTFS passengers make multimodal trips (using stops from different modes of transport) and switch between stops of the same transport mode, while working only with the following GTFS files: routes.txt, trips.txt, shapes.txt, stop_times.txt, stops.txt, calendar.txt, and agency.txt?
Hello @AmparoAlvarez. I am Elias, I am the Community Manager for GTFS at MobilityData. I brought this question up with the team they wanted me to share this with you:
Each leg of the entire journey can be modelled as a trip from a stop to a stop. As long a mode is representable by GTFS (bus, tram, ferry, metro, rail, cable car), then there shouldn't be any problem in modelling multi-leg journeys since each leg is represented as:
route_id taking trip_id from stop_id_1 to stop_id_2
GTFS has no blocker from modelling this. The only issue is if a mode is a car or a bike etc.
Additionally, I would recommend consulting the official documentation on the newly re-designed GTFS.org.
(PS to the admins and moderators, we saw GTFS pop up in our feeds and we had to jump on it, feel free to reach out to me for anything GTFS related.)
