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

4 errors, 12 warnings

Validation carried out using the current GTFS file and the GTFS-RT the 2026-01-24 at 08:02 Europe/Paris using the MobilityData GTFS-RT validator.

Errors

Vehicle position outside agency coverage area E028 4 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 18 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 20 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 190 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 61 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 4 errors

Timestamps should be populated for all elements

Sample errors
  • vehicle_id 18 does not have a timestamp
  • vehicle_id 20 does not have a timestamp
  • vehicle_id 190 does not have a timestamp
  • vehicle_id 61 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 52 sec old which is greater than the recommended age of 65 seconds

schedule_relationship not populated W009 7 errors

trip.schedule_relationship and stop_time_update.schedule_relationship should be populated

Sample errors
  • trip_id bc706336-e4e1-4606-8404-9d7d2a16812c does not have a schedule_relationship
  • trip_id 9bb232b1-b6bd-407c-b40d-0eddd2870d3a does not have a schedule_relationship
  • trip_id f0e26de0-5d41-43c1-8c46-b9977a9d53f4 does not have a schedule_relationship
  • trip_id b43b2498-70a7-4140-a11c-ae64c6e0f2c3 does not have a schedule_relationship
  • trip_id 8acccb20-9323-4e5c-961c-3cf66d21d1b4 does not have a schedule_relationship
