Here is a recap of all the error types encountered over the last 30 days.

|---|---|---|---|
| E011 | All stop_ids referenced in GTFS-rt feeds must exist in GTFS stops.txt | 592 | 29 times (100 % of validations) |
| E022 | stop_time_update arrival/departure times between sequential stops should always increase - they should never be the same or decrease. | 1 738 | 29 times (100 % of validations) |
| W002 | vehicle_id should be populated for TripUpdates and VehiclePositions | 801 | 29 times (100 % of validations) |
| E002 | stop_time_updates for a given trip_id must be strictly sorted by increasing stop_sequence | 200 | 27 times (93 % of validations) |
| W001 | Timestamps should be populated for all elements | 1 025 | 22 times (76 % of validations) |
| E037 | Sequential GTFS-rt trip stop_time_updates shouldn't have the same stop_id | 85 | 21 times (72 % of validations) |
| E051 | All stop_time_update stop_sequences in GTFS-realtime data must appear in GTFS stop_times.txt for that trip | 69 | 18 times (62 % of validations) |
| E009 | If a GTFS trip contains multiple references to the same stop_id (i.e., the vehicle visits the same stop_id more than once in the same trip), then GTFS-rt stop_time_updates for this trip must include stop_sequence | 13 | 5 times (17 % of validations) |
| E025 | 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. | 1 | 1 times (3 % of validations) |
