Hello everyone,

in the documentation it says start_pickup_drop_off_window and end_pickup_drop_off_window are

• Required if stop_times.stop_id refers to stop_areas.area_id or id from locations.geojson.

To my understanding, this would mean that departures from areas always require an interval.
However, there are indeed on-demand services that run between two areas with fixed departure times.
Here is an example for area relations with fixed departures: https://www.vor.at/fileadmin/CONTENT/Downloads/Folder/Anrufsammeltaxi_Folder/AST_Infoblatt_MOSTI.pdf
I do understand that in reality the vehicle will start picking up passenger from that departure time on, but so do the operators that design there timetables in such a way.

Can someone clarify if this indeed currently not intended in GTFS-Flex or if I may have simply misunderstood it?

Currently, it would probably have to be solved in such a way that in this case the time window is filled with identical start and end times.

Thank You!
