We test this resource download availability every hour by making an HTTP 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

3 errors, 12 warnings

Validation carried out using the current GTFS file and the GTFS-RT the 2025-12-31 at 08:04 Europe/Paris using the MobilityData GTFS-RT validator.

Errors

Vehicle position outside agency coverage area E028 2 errors

The vehicle position should be inside the agency coverage area. This is defined as within roughly 1/8 of a mile (200 meters) of the GTFS shapes.txt data, or stops.txt locations if the GTFS feed doesn't include shapes.txt.

Sample errors
  • vehicle.id 54 at (0.0,0.0) is more than 1609.0 meters (1.00 mile(s)) outside entire GTFS shapes.txt coverage area - vehicle should be within area
  • vehicle.id 8 at (0.0,0.0) is more than 1609.0 meters (1.00 mile(s)) outside entire GTFS shapes.txt coverage area - vehicle should be within area

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 60 trip_id 8acccb20-9323-4e5c-961c-3cf66d21d1b4 at (49.21706,6.857169) 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

timestamp not populated W001 2 errors

Timestamps should be populated for all elements

Sample errors
  • vehicle_id 54 does not have a timestamp
  • vehicle_id 8 does not have a timestamp

Header timestamp is older than 65 seconds W008 1 error

The data in a GTFS-realtime feed should always be less than one minute old

Sample errors
  • header.timestamp is 1 min 58 sec old which is greater than the recommended age of 65 seconds

schedule_relationship not populated W009 9 errors

trip.schedule_relationship and stop_time_update.schedule_relationship should be populated

Sample errors
  • trip_id cc2a5ad5-9315-41e6-b477-d1fc04eb0b9d does not have a schedule_relationship
  • trip_id b5a9c3e7-ce32-4d64-a5a3-349a977a85c8 does not have a schedule_relationship
  • trip_id 28e0fc94-9e42-46d3-9d77-a4981a6ab4b1 does not have a schedule_relationship
  • trip_id 8acccb20-9323-4e5c-961c-3cf66d21d1b4 does not have a schedule_relationship
  • trip_id 8cc89595-5360-49fd-ab8a-af60a414efdc does not have a schedule_relationship
