Errors
Sequential stop_time_update times are not increasing E022 6 errors
stop_time_update arrival/departure times between sequential stops should always increase - they should never be the same or decrease.
Sample errors
- trip_id 1288 stop_sequence 15 arrival_time 07:56:04 (1769756164) is equal to previous stop departure_time 07:56:04 (1769756164) - times must increase between two sequential stops
- trip_id 1285 stop_sequence 8 arrival_time 07:52:25 (1769755945) is equal to previous stop departure_time 07:52:25 (1769755945) - times must increase between two sequential stops
- trip_id 1279 stop_sequence 13 arrival_time 07:52:19 (1769755939) is less than previous stop arrival_time 08:21:00 (1769757660) - times must increase between two sequential stops
- trip_id 1279 stop_sequence 13 arrival_time 07:52:19 (1769755939) is less than previous stop departure_time 08:29:00 (1769758140) - times must increase between two sequential stops
- trip_id 1279 stop_sequence 13 departure_time 07:52:30 (1769755950) is less than previous stop departure_time 08:29:00 (1769758140) - times must increase between two sequential stops
stop_time_update departure time is before arrival time E025 2 errors
Within the same stop_time_update, arrival and departures times can be the same, or the departure time can be later than the arrival time - the departure time should never come before the arrival time.
Sample errors
- trip_id 984 stop_sequence 2 departure_time 07:59:02 (1769756342) is less than the same stop arrival_time 07:59:29 (1769756369) - departure time must be equal to or greater than arrival time
- trip_id 564 stop_sequence 3 departure_time 07:59:55 (1769756395) is less than the same stop arrival_time 08:00:04 (1769756404) - departure time must be equal to or greater than arrival time
GTFS-rt stop_time_update stop_sequence and stop_id do not match GTFS E045 1 error
If GTFS-rt stop_time_update contains both stop_sequence and stop_id, the values must match the GTFS data in stop_times.txt
Sample errors
- GTFS-rt trip_id 730 stop_sequence 2 has stop_id 252 but GTFS stop_sequence 2 has stop_id 318 - stop_ids should be the same
