curl -H "Authorization: Bearer $MOBILITYTWIN_TOKEN" -o gtfs-rt-vehicle-position.pb "https://api.mobilitytwin.brussels/tec/gtfs-rt-vehicle-position"Real-time positions of TEC vehicles from the Belgian Mobility API, with bearing, speed, current stop sequence and the trip being served. As published, speed is in km/h although GTFS-RT specifies m/s, and a vehicle without a GPS fix is reported at 0,0 (about one in a thousand positions).
