Errors
Sequential stop_time_update times are not increasing E022 11 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 07:57:04 (1770101824) is equal to previous stop departure_time 07:57:04 (1770101824) - times must increase between two sequential stops
- trip_id 1285 stop_sequence 8 arrival_time 07:51:10 (1770101470) is equal to previous stop departure_time 07:51:10 (1770101470) - times must increase between two sequential stops
- trip_id 993 stop_sequence 12 arrival_time 08:01:41 (1770102101) is equal to previous stop departure_time 08:01:41 (1770102101) - times must increase between two sequential stops
- trip_id 1279 stop_sequence 13 arrival_time 07:51:53 (1770101513) is less than previous stop arrival_time 08:22:33 (1770103353) - times must increase between two sequential stops
- trip_id 1279 stop_sequence 13 arrival_time 07:51:53 (1770101513) is less than previous stop departure_time 08:30:33 (1770103833) - times must increase between two sequential stops
stop_time_update departure time is before arrival time E025 4 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 400 stop_sequence 7 departure_time 08:09:59 (1770102599) is less than the same stop arrival_time 08:10:27 (1770102627) - departure time must be equal to or greater than arrival time
- trip_id 795 stop_sequence 13 departure_time 08:10:16 (1770102616) is less than the same stop arrival_time 08:10:19 (1770102619) - departure time must be equal to or greater than arrival time
- trip_id 391 stop_sequence 4 departure_time 08:10:12 (1770102612) is less than the same stop arrival_time 08:10:25 (1770102625) - departure time must be equal to or greater than arrival time
- trip_id 846 stop_sequence 3 departure_time 08:07:14 (1770102434) is less than the same stop arrival_time 08:10:24 (1770102624) - departure time must be equal to or greater than arrival time
