Procedure, device and computer program for determining a traffic light phase of a traffic light system

摘要

Procedure for determining a traffic light phase of a traffic light system, where the traffic light is located on a road of a vehicle, with:-(S301) call an event time (Tevent) at which the vehicle is at the traffic light;-(S302) call a first time recording point (Ti) at which the vehicle (1) is recording the traffic light for the first time;-(S303) call a last time recording point (Te) at which the vehicle (1) last recorded the traffic light;-(S304) recall a phase course of the traffic lights from the first time (Ti) to the last time (Te);-(S307) Determine a traffic light phase at the time of the event (Tevent) by comparing the phase sequence called with a reference traffic light cycle, where the reference traffic light cycle has a predetermined traffic time and phase times (Xrot) of the reference traffic light cycle are modelled as random variables.
