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

34 errors, 114 warnings

Validation carried out using the current GTFS file and the GTFS-RT the 2026-01-04 at 08:11 Europe/Paris using the MobilityData GTFS-RT validator.

Errors

Sequential stop_time_update times are not increasing E022 34 errors

stop_time_update arrival/departure times between sequential stops should always increase - they should never be the same or decrease.

Sample errors
  • trip_id 1583123112-16 stop_id 2459 arrival_time 07:41:30 (1767508890) is equal to previous stop arrival_time 07:41:30 (1767508890) - times must increase between two sequential stops
  • trip_id 1583123112-16 stop_id 2459 arrival_time 07:41:30 (1767508890) is equal to previous stop departure_time 07:41:30 (1767508890) - times must increase between two sequential stops
  • trip_id 1583017164-16 stop_id 594 arrival_time 08:11:32 (1767510692) is less than previous stop arrival_time 08:11:35 (1767510695) - times must increase between two sequential stops
  • trip_id 1583017164-16 stop_id 594 arrival_time 08:11:32 (1767510692) is less than previous stop departure_time 08:11:35 (1767510695) - times must increase between two sequential stops
  • trip_id 1583017164-16 stop_id 594 departure_time 08:11:32 (1767510692) is less than previous stop departure_time 08:11:35 (1767510695) - times must increase between two sequential stops
