Transition table from the driving activity to the next activity.

Next activityCriteria

BarrierWhen the vehicle first reaches the barrier, without any vehicle between itself and the barrier, and the vehicle speed first falls below 1 km/h

Drive-throughWhen the first toll booth (or order point) is reached and the vehicle speed first falls below 1 km/h

Drop-offWhen the vehicle speed first falls below 1 km/h and a door to the vehicle is opened. Manual verification that a passenger is exiting the vehicle is required (from dashcam or seatbelt signals). The vehicle cannot be turned off for this label to be true

ManoeuvreWhen the vehicle speed first falls below 1 km/h or reverse gear is selected. Manual verification that this is due to a manoeuvre is required

ParkedWhen the vehicle speed first falls below 1 km/h and the vehicle stops. The gear does not have to be in park, but manual verification that the stop is not due to a pick-up, drop-off or traffic is required

Pick-upWhen the vehicle speed first falls below 1 km/h and a door to the vehicle is opened. Manual verification that a passenger is entering the vehicle is required (from dashcam or seatbelt signals). The vehicle cannot be turned off for this label to be true

TrafficWhen the vehicle speed first falls below 5 km/h as a consequence of encountering congestion or road infrastructure that causes either 5 km/h not to be reached within 10 seconds or the vehicle speed to fall below 1 km/h within 10 seconds
