HEAD request with a timeout of 5 seconds. If we detect a downtime, we perform subsequent tests every 10 minutes, until the resource is back online.For SIRI and SIRI Lite feeds, we perform a
GET request: a 401 or 405 status code is considered successful. In case of HTTP 500, the feed will be considered unavailable, unless the body appears to contain SOAP.Validation details

Errors
Sequential stop_time_update times are not increasing E022 77 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 5359235979280384:7 stop_sequence 23 arrival_time 08:13:46 (1770189226) is less than previous stop departure_time 08:15:00 (1770189300) - times must increase between two sequential stops
- trip_id 5359235979280384:7 stop_sequence 23 departure_time 08:14:58 (1770189298) is less than previous stop departure_time 08:15:00 (1770189300) - times must increase between two sequential stops
- trip_id 5359235979280384:7 stop_sequence 24 arrival_time 08:14:32 (1770189272) is less than previous stop departure_time 08:14:58 (1770189298) - times must increase between two sequential stops
- trip_id 5359235979280384:7 stop_sequence 25 arrival_time 08:15:18 (1770189318) is less than previous stop departure_time 08:15:51 (1770189351) - times must increase between two sequential stops
- trip_id 5359235979280384:7 stop_sequence 26 arrival_time 08:16:05 (1770189365) is less than previous stop departure_time 08:16:44 (1770189404) - times must increase between two sequential stops
Vehicle position far from trip shape E029 1 error
The vehicle position should be within a certain distance of the GTFS shapes.txt data for the current trip unless there is a Service Alert with the Effect of DETOUR for this trip_id.
Sample errors
- vehicle.id zenbus:Vehicle:709630001:LOC trip_id 5988828524314624:4 at (48.70783,7.709779) is more than 200.0 meters (0.12 mile(s)) from the GTFS trip shape - vehicle should be near trip shape or on DETOUR
Warnings
vehicle_id not populated W002 1 error
vehicle_id should be populated for TripUpdates and VehiclePositions
Sample errors
- trip_id 6542731733106688:2 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 6542731733106688:2 is in TripUpdates but not in VehiclePositions feed
