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 07:54:48 (1769496888) is equal to previous stop departure_time 07:54:48 (1769496888) - times must increase between two sequential stops
- trip_id 1285 stop_sequence 8 arrival_time 07:55:32 (1769496932) is equal to previous stop departure_time 07:55:32 (1769496932) - times must increase between two sequential stops
- trip_id 1279 stop_sequence 13 arrival_time 07:54:26 (1769496866) is less than previous stop arrival_time 08:22:25 (1769498545) - times must increase between two sequential stops
- trip_id 1279 stop_sequence 13 arrival_time 07:54:26 (1769496866) is less than previous stop departure_time 08:30:25 (1769499025) - times must increase between two sequential stops
- trip_id 1279 stop_sequence 13 departure_time 07:54:39 (1769496879) is less than previous stop departure_time 08:30:25 (1769499025) - times must increase between two sequential stops
stop_time_update departure time is before arrival time E025 5 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 812 stop_sequence 11 departure_time 08:09:12 (1769497752) is less than the same stop arrival_time 08:10:09 (1769497809) - departure time must be equal to or greater than arrival time
- trip_id 795 stop_sequence 13 departure_time 08:10:11 (1769497811) is less than the same stop arrival_time 08:10:28 (1769497828) - departure time must be equal to or greater than arrival time
- trip_id 1599 stop_sequence 10 departure_time 08:10:06 (1769497806) is less than the same stop arrival_time 08:10:11 (1769497811) - departure time must be equal to or greater than arrival time
- trip_id 391 stop_sequence 9 departure_time 08:09:50 (1769497790) is less than the same stop arrival_time 08:10:07 (1769497807) - departure time must be equal to or greater than arrival time
- trip_id 846 stop_sequence 3 departure_time 08:07:01 (1769497621) is less than the same stop arrival_time 08:10:29 (1769497829) - departure time must be equal to or greater than arrival time
