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

21 errors, 244 warnings

Validation carried out using the current GTFS file and the GTFS-RT the 2026-03-05 at 08:11 Europe/Paris using the MobilityData GTFS-RT validator.

Errors

Sequential stop_time_update times are not increasing E022 16 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 95118_260224-5446 stop_sequence 1 arrival_time 08:45:00 (1772696700) is less than previous stop arrival_time 08:48:44 (1772696924) - times must increase between two sequential stops
  • trip_id 95118_260224-5446 stop_sequence 1 arrival_time 08:45:00 (1772696700) is less than previous stop departure_time 08:48:44 (1772696924) - times must increase between two sequential stops
  • trip_id 95118_260224-5446 stop_sequence 1 departure_time 08:45:00 (1772696700) is less than previous stop departure_time 08:48:44 (1772696924) - times must increase between two sequential stops
  • trip_id 95118_260224-5446 stop_sequence 1 departure_time 08:45:00 (1772696700) is less than previous stop arrival_time 08:48:44 (1772696924) - times must increase between two sequential stops
  • trip_id 95106_260224-5446 stop_sequence 1 arrival_time 09:00:00 (1772697600) is less than previous stop arrival_time 09:10:42 (1772698242) - times must increase between two sequential stops

GTFS-rt stop_sequence not found in GTFS data E051 5 errors

All stop_time_update stop_sequences in GTFS-realtime data must appear in GTFS stop_times.txt for that trip

Sample errors
  • GTFS-rt trip_id 95107_260224-5446 contains stop_sequence 0 that does not exist in GTFS stop_times.txt for this trip
  • GTFS-rt trip_id 95118_260224-5446 contains stop_sequence 0 that does not exist in GTFS stop_times.txt for this trip
  • GTFS-rt trip_id 95106_260224-5446 contains stop_sequence 0 that does not exist in GTFS stop_times.txt for this trip
  • GTFS-rt trip_id 95117_260224-5446 contains stop_sequence 0 that does not exist in GTFS stop_times.txt for this trip
  • GTFS-rt trip_id 95105_260224-5446 contains stop_sequence 0 that does not exist in GTFS stop_times.txt for this trip
