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

❌104 errors, 4 warnings

Validation carried out using the current GTFS file and the GTFS-RT the 2024-12-20 at 08:00 Europe/Paris using the MobilityData GTFS-RT validator.

Errors

Sequential stop_time_update times are not increasing E022 104 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 18-5B-9-B-073000 stop_id 503 arrival_time 08:18:35 (1734679115) is equal to previous stop arrival_time 08:18:35 (1734679115) - times must increase between two sequential stops
trip_id 18-5B-9-B-073000 stop_id 503 arrival_time 08:18:35 (1734679115) is equal to previous stop departure_time 08:18:35 (1734679115) - times must increase between two sequential stops
trip_id 18-5B-9-B-073000 stop_id 503 departure_time 08:18:35 (1734679115) is equal to previous stop departure_time 08:18:35 (1734679115) - times must increase between two sequential stops
trip_id 18-5B-9-B-073000 stop_id 503 departure_time 08:18:35 (1734679115) is equal to previous stop arrival_time 08:18:35 (1734679115) - times must increase between two sequential stops
trip_id 18-10-10-B-074401 stop_id 31 arrival_time 08:28:25 (1734679705) is less than previous stop arrival_time 08:28:26 (1734679706) - times must increase between two sequential stops
