stop_sequence |
Provide stop_sequence whenever possible, as it unambiguously resolves to a GTFS stop time in stop_times.txt unlike stop_id, which can occur more than once in a trip (e.g., loop route). |
arrival |
Arrival times between sequential stops should increase - they should not be the same or decrease. |
|
Arrival time (specified in StopTimeEvent) should be before the departure time for the same stop if a layover or dwell time is expected - otherwise, arrival time should be be the same as departure time. |
departure |
Departure times between sequential stops should increase - they should not be the same or decrease. |
|
Departure time (specified in StopTimeEvent) should be the same as the arrival time for the same stop if no layover or dwell time is expected - otherwise, departure time should be after arrival time . |
