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.

Warnings

vehicle_id not populated W002 5 errors

vehicle_id should be populated for TripUpdates and VehiclePositions

Sample errors

trip_id 3 scolaire 7:32 does not have a vehicle_id
trip_id 4 scolaire 07:35 does not have a vehicle_id
trip_id 5 scolaire 07:29 does not have a vehicle_id
trip_id 1 scolaire 07:41 does not have a vehicle_id
trip_id 2 scolaire 8:00 does not have a vehicle_id

Header timestamp is older than 65 seconds W008 1 error

The data in a GTFS-realtime feed should always be less than one minute old

Sample errors

header.timestamp is 13 min 18 sec old which is greater than the recommended age of 65 seconds

schedule_relationship not populated W009 10 errors

trip.schedule_relationship and stop_time_update.schedule_relationship should be populated

Sample errors

trip_id 3 scolaire 7:32 stop_sequence 26 (and potentially more for this trip) does not have a schedule_relationship
