Errors
Sequential stop_time_update times are not increasing E022 133 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 1555 stop_sequence 65 arrival_time 11:40:37 (1775374837) is less than previous stop departure_time 11:40:41 (1775374841) - times must increase between two sequential stops
- trip_id 1555 stop_sequence 68 arrival_time 11:42:25 (1775374945) is less than previous stop departure_time 11:42:27 (1775374947) - times must increase between two sequential stops
- trip_id 1555 stop_sequence 69 arrival_time 11:42:59 (1775374979) is less than previous stop departure_time 11:43:17 (1775374997) - times must increase between two sequential stops
- trip_id 1555 stop_sequence 70 arrival_time 11:43:33 (1775375013) is less than previous stop departure_time 11:44:04 (1775375044) - times must increase between two sequential stops
- trip_id 1555 stop_sequence 71 arrival_time 11:44:05 (1775375045) is less than previous stop departure_time 11:44:51 (1775375091) - times must increase between two sequential stops
GTFS-rt stop_time_update stop_sequence and stop_id do not match GTFS E045 267 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 1668 stop_sequence 57 has stop_id SJ0040C but GTFS stop_sequence 57 has stop_id SJ0035C - stop_ids should be the same
- GTFS-rt trip_id 1668 stop_sequence 58 has stop_id SJ03920C but GTFS stop_sequence 58 has stop_id SJ0040C - stop_ids should be the same
- GTFS-rt trip_id 1668 stop_sequence 59 has stop_id SJ03925C but GTFS stop_sequence 59 has stop_id SJ03920C - stop_ids should be the same
- GTFS-rt trip_id 1668 stop_sequence 60 has stop_id SJ0050C but GTFS stop_sequence 60 has stop_id SJ03925C - stop_ids should be the same
- GTFS-rt trip_id 1677 stop_sequence 42 has stop_id SJ00950C but GTFS stop_sequence 42 has stop_id SJ00940C - stop_ids should be the same
GTFS-rt stop_sequence not found in GTFS data E051 1 error
All stop_time_update stop_sequences in GTFS-realtime data must appear in GTFS stop_times.txt for that trip
Sample errors
- GTFS-rt trip_id 1519 contains stop_sequence 0 that does not exist in GTFS stop_times.txt for this trip
Warnings
vehicle_id not populated W002 1 error
vehicle_id should be populated for TripUpdates and VehiclePositions
Sample errors
- trip_id 1677 does not have a vehicle_id
ID in one feed missing from the other W003 1 error
a trip_id that is provided in the VehiclePositions feed should be provided in the TripUpdates feed, and a vehicle_id that is provided in the TripUpdates feed should be provided in the VehiclePositions feed
Sample errors
- trip_id 1677 is in TripUpdates but not in VehiclePositions feed
