Errors
Sequential stop_time_update times are not increasing E022 14 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 1283 stop_sequence 6 arrival_time 07:30:12 (1734676212) is less than previous stop arrival_time 07:59:44 (1734677984) - times must increase between two sequential stops
- trip_id 1283 stop_sequence 6 arrival_time 07:30:12 (1734676212) is less than previous stop departure_time 08:02:03 (1734678123) - times must increase between two sequential stops
- trip_id 1283 stop_sequence 6 departure_time 07:30:20 (1734676220) is less than previous stop departure_time 08:02:03 (1734678123) - times must increase between two sequential stops
- trip_id 1283 stop_sequence 6 departure_time 07:30:20 (1734676220) is less than previous stop arrival_time 07:59:44 (1734677984) - times must increase between two sequential stops
- trip_id 1283 stop_sequence 10 arrival_time 07:13:06 (1734675186) is less than previous stop arrival_time 08:13:03 (1734678783) - times must increase between two sequential stops
stop_time_update departure time is before arrival time E025 1 error
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 815 stop_sequence 3 departure_time 08:01:09 (1734678069) is less than the same stop arrival_time 08:01:27 (1734678087) - departure time must be equal to or greater than arrival time
