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

5 errors, 720 warnings

Validation carried out using the current GTFS file and the GTFS-RT the 2025-04-19 at 09:04 Europe/Paris using the MobilityData GTFS-RT validator.

Errors

Sequential stop_time_update times are not increasing E022 4 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 365 stop_sequence 12 arrival_time 08:59:08 (1745045948) is less than previous stop arrival_time 09:03:38 (1745046218) - times must increase between two sequential stops
  • trip_id 365 stop_sequence 12 arrival_time 08:59:08 (1745045948) is less than previous stop departure_time 09:03:55 (1745046235) - times must increase between two sequential stops
  • trip_id 365 stop_sequence 12 departure_time 08:59:18 (1745045958) is less than previous stop departure_time 09:03:55 (1745046235) - times must increase between two sequential stops
  • trip_id 365 stop_sequence 12 departure_time 08:59:18 (1745045958) is less than previous stop arrival_time 09:03:38 (1745046218) - times must increase between two sequential stops

stop_time_update departure time is before arrival time E025 1 error

Within the same stop_time_update, arrival and departures times can be the same, or the departure time can be later than the arrival time - the departure time should never come before the arrival time.

Sample errors
  • trip_id 539 stop_sequence 24 departure_time 09:04:07 (1745046247) is less than the same stop arrival_time 09:04:12 (1745046252) - departure time must be equal to or greater than arrival time
