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.

Sample errors

trip_id 300000124 and vehicle_id narbonne-605 pairing in VehiclePositions does not match trip_id 300000127 and vehicle_id narbonne-605 pairing in TripUpdates feed and trip block_ids aren't the same - ID pairing between feeds should match

GTFS-rt stop_sequence not found in GTFS data E051 3 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 300000358 contains stop_sequence 27 that does not exist in GTFS stop_times.txt for this trip
GTFS-rt trip_id 300000124 contains stop_sequence 26 that does not exist in GTFS stop_times.txt for this trip
GTFS-rt trip_id 300000796 contains stop_sequence 17 that does not exist in GTFS stop_times.txt for this trip

Warnings

ID in one feed missing from the other W003 1 error

a trip_id that is provided in the VehiclePositions feed should be provided in the TripUpdates feed, and a vehicle_id that is provided in the TripUpdates feed should be provided in the VehiclePositions feed

Sample errors
