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

651 errors, 158 warnings

Validation carried out using the current GTFS file and the GTFS-RT the 2025-12-02 at 08:09 Europe/Paris using the MobilityData GTFS-RT validator.

Errors

Sequential stop_time_update times are not increasing E022 496 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 176876-2020-_ABCDSN-Semaine-01 stop_sequence 35 arrival_time 08:22:32 (1764660152) is equal to previous stop arrival_time 08:22:32 (1764660152) - times must increase between two sequential stops
  • trip_id 176876-2020-_ABCDSN-Semaine-01 stop_sequence 35 arrival_time 08:22:32 (1764660152) is equal to previous stop departure_time 08:22:32 (1764660152) - times must increase between two sequential stops
  • trip_id 176876-2020-_ABCDSN-Semaine-01 stop_sequence 35 departure_time 08:22:32 (1764660152) is equal to previous stop departure_time 08:22:32 (1764660152) - times must increase between two sequential stops
  • trip_id 176876-2020-_ABCDSN-Semaine-01 stop_sequence 35 departure_time 08:22:32 (1764660152) is equal to previous stop arrival_time 08:22:32 (1764660152) - times must increase between two sequential stops
  • trip_id ebc39ad1-bce6-43aa-bea3-f6c05ef5827b stop_sequence 27 arrival_time 08:19:23 (1764659963) is equal to previous stop arrival_time 08:19:23 (1764659963) - times must increase between two sequential stops

trip start_time does not match first GTFS arrival_time E023 1 error

For normal scheduled trips (i.e., not defined in frequencies.txt), the GTFS-realtime trip start_time must match the first GTFS arrival_time in stop_times.txt for this trip

Sample errors
  • GTFS-rt trip_id d3525cf6-5cc7-4697-9b63-1546088dddc8 start_time is 07:45:00 and GTFS initial arrival_time is 07:49:00 - times do not match

stop_time_update departure time is before arrival time E025 3 errors

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 182865-2020-_ABCDSN-Semaine-01 stop_sequence 2 departure_time 08:08:39 (1764659319) is less than the same stop arrival_time 08:08:45 (1764659325) - departure time must be equal to or greater than arrival time
  • trip_id 3ca92c7d-1298-4599-9345-0386f3d0040a stop_sequence 25 departure_time 11:36:23 (1764671783) is less than the same stop arrival_time 11:37:23 (1764671843) - departure time must be equal to or greater than arrival time
  • trip_id f570359b-7224-4ffe-8b90-853813fa8c29 stop_sequence 25 departure_time 18:34:23 (1764696863) is less than the same stop arrival_time 18:35:23 (1764696923) - departure time must be equal to or greater than arrival time

GTFS-rt stop_time_update stop_sequence and stop_id do not match GTFS E045 145 errors

If GTFS-rt stop_time_update contains both stop_sequence and stop_id, the values must match the GTFS data in stop_times.txt

Sample errors
  • GTFS-rt trip_id d3525cf6-5cc7-4697-9b63-1546088dddc8 stop_sequence 1 has stop_id STP-2001R but GTFS stop_sequence 1 has stop_id 05020 - stop_ids should be the same
  • GTFS-rt trip_id d3525cf6-5cc7-4697-9b63-1546088dddc8 stop_sequence 2 has stop_id 05020 but GTFS stop_sequence 2 has stop_id 1705A - stop_ids should be the same
  • GTFS-rt trip_id d3525cf6-5cc7-4697-9b63-1546088dddc8 stop_sequence 3 has stop_id 1705A but GTFS stop_sequence 3 has stop_id 1706A - stop_ids should be the same
  • GTFS-rt trip_id d3525cf6-5cc7-4697-9b63-1546088dddc8 stop_sequence 4 has stop_id 1706A but GTFS stop_sequence 4 has stop_id 1707A - stop_ids should be the same
  • GTFS-rt trip_id d3525cf6-5cc7-4697-9b63-1546088dddc8 stop_sequence 5 has stop_id 1707A but GTFS stop_sequence 5 has stop_id 1700A - stop_ids should be the same

GTFS-rt stop_sequence not found in GTFS data E051 6 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 30b080b0-b9d8-4db9-bcd9-9cbd037bb3bc contains stop_sequence 11 that does not exist in GTFS stop_times.txt for this trip
