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 07:54:17 (1769410457) is equal to previous stop departure_time 07:54:17 (1769410457) - times must increase between two sequential stops
- trip_id 1285 stop_sequence 8 arrival_time 07:57:57 (1769410677) is equal to previous stop departure_time 07:57:57 (1769410677) - times must increase between two sequential stops
- trip_id 1279 stop_sequence 13 arrival_time 07:53:03 (1769410383) is less than previous stop arrival_time 08:22:27 (1769412147) - times must increase between two sequential stops
- trip_id 1279 stop_sequence 13 arrival_time 07:53:03 (1769410383) is less than previous stop departure_time 08:30:27 (1769412627) - times must increase between two sequential stops
- trip_id 1279 stop_sequence 13 departure_time 07:53:14 (1769410394) is less than previous stop departure_time 08:30:27 (1769412627) - 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 496 stop_sequence 15 departure_time 08:03:03 (1769410983) is less than the same stop arrival_time 08:03:11 (1769410991) - departure time must be equal to or greater than arrival time
