Data sets in GTFS format include information on lines, stops, routes, timetable data, etc. and are integrated into map services such as Google Maps, among other things.

Our GTFS data packages provide you with all the important timetable data for our rnv lines. You can find detailed documentation on how the GTFS data sets are structured directly on Google: "GTFS Specification" We store them automatically in our rnv-GTFS resource always the most current data set.

What else you should know about our GTFS packages: Not all routes have trips all year round. Certain lines only run during certain periods. That's why there are many routes that temporarily do not contain any trips. Don't let this confuse you, this is correct. As route_type we use the so-called "⇒Extended GTFS Route Types". The "empty" routes have the default value 3. The characteristic 704 stands for bus lines (Regional Bus Service) and the 900 stands for train (Tram Service).
