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

❌1 error

Validation carried out using the current GTFS file and the GTFS-RT the 2026-03-15 at 08:08 Europe/Paris using the MobilityData GTFS-RT validator.

Errors

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 85 trip_id 1_71051362 at (-21.291948,55.404373) is more than 200.0 meters (0.12 mile(s)) from the GTFS trip shape - vehicle should be near trip shape or on DETOUR
