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 07:54:18 (1769064858) is equal to previous stop departure_time 07:54:18 (1769064858) - times must increase between two sequential stops
- trip_id 1285 stop_sequence 8 arrival_time 07:56:02 (1769064962) is equal to previous stop departure_time 07:56:02 (1769064962) - times must increase between two sequential stops
- trip_id 1279 stop_sequence 13 arrival_time 07:53:51 (1769064831) is less than previous stop arrival_time 08:21:59 (1769066519) - times must increase between two sequential stops
- trip_id 1279 stop_sequence 13 arrival_time 07:53:51 (1769064831) is less than previous stop departure_time 08:29:59 (1769066999) - times must increase between two sequential stops
- trip_id 1279 stop_sequence 13 departure_time 07:54:02 (1769064842) is less than previous stop departure_time 08:29:59 (1769066999) - 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 464 stop_sequence 19 departure_time 08:05:16 (1769065516) is less than the same stop arrival_time 08:05:17 (1769065517) - 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 2 errors
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 1309 stop_sequence 7 has stop_id 2778 but GTFS stop_sequence 7 has stop_id 2680 - stop_ids should be the same
- GTFS-rt trip_id 1308 stop_sequence 3 has stop_id 2778 but GTFS stop_sequence 3 has stop_id 2680 - stop_ids should be the same
