GTFS-RT Trip updates
STIB: brussels metro, tram and bus operator
- Format
- GTFS-RT
- Updates
- On request, from the latest vehicle-trip snapshot (every 20 seconds)
curl -H "Authorization: Bearer $MOBILITYTWIN_TOKEN" -o gtfs-rt-trip-update.pb "https://api.mobilitytwin.brussels/stib/gtfs-rt-trip-update"Predicted arrivals for STIB/MIVB as a standard GTFS Realtime feed, built from vehicle-trip. Produced by MobilityTwin.Brussels, not an official STIB feed.
One TripUpdate per trip that has a vehicle on it: the delay measured at the last stop the vehicle called at is applied to every stop still ahead of it (arrival and departure carry both delay and absolute time). Trips with no vehicle on them are left out rather than declared on time, and there are no cancellations: the source has no signal for them.
A binary GTFS Realtime message (Protocol Buffers). Decode it with gtfs-realtime-bindings.
Parameters
| Name | Meaning |
|---|---|
start_timestamp | Start of the range, in Unix seconds or ISO 8601. Without any timestamp, the last hour is used; with only one, the hour starting or ending at it. |
end_timestamp | End of the range, in Unix seconds or ISO 8601. |
