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

❌2 errors, 9 warnings

Validation carried out using the current GTFS file and the GTFS-RT the 2026-01-31 at 08:08 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 60 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 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

Warnings

timestamp not populated W001 2 errors

Timestamps should be populated for all elements

Sample errors
  • vehicle_id 60 does not have a timestamp
  • vehicle_id 54 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 2 min 12 sec old which is greater than the recommended age of 65 seconds

schedule_relationship not populated W009 6 errors

trip.schedule_relationship and stop_time_update.schedule_relationship should be populated

Sample errors
  • trip_id 2c61ca2f-3976-4643-a5de-35c86a314462 does not have a schedule_relationship
  • trip_id 9bb232b1-b6bd-407c-b40d-0eddd2870d3a does not have a schedule_relationship
  • trip_id 8cc89595-5360-49fd-ab8a-af60a414efdc does not have a schedule_relationship
  • trip_id f9db1194-258a-42e8-94da-86e787440ad6 does not have a schedule_relationship
  • trip_id b5a9c3e7-ce32-4d64-a5a3-349a977a85c8 does not have a schedule_relationship
