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, 22 warnings

Validation carried out using the current GTFS file and the GTFS-RT the 2026-01-21 at 08:07 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 14 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 13 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 194 trip_id 8cdb3360-1b74-4c36-89ff-e9bdc46f0b78 at (49.18725,6.910864) 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 14 does not have a timestamp
  • vehicle_id 13 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 56 sec old which is greater than the recommended age of 65 seconds

schedule_relationship not populated W009 19 errors

trip.schedule_relationship and stop_time_update.schedule_relationship should be populated

Sample errors
  • trip_id 69c3bac2-fa43-4dca-bc91-7116997f4688 does not have a schedule_relationship
  • trip_id 9fcb28c2-5e63-4c3f-a55c-f969e241c571 does not have a schedule_relationship
  • trip_id cb1bff29-4687-41b8-9853-3772ff916575 does not have a schedule_relationship
  • trip_id 662a9652-381b-4a78-ba0d-7f0f21efc61f does not have a schedule_relationship
  • trip_id 8acccb20-9323-4e5c-961c-3cf66d21d1b4 does not have a schedule_relationship
