Abstract

A traffic light control system for controlling the traffic lights (4,5,6) in at least one intersection (10,11,12,...,26) based on the position of a vehicle (1). The system comprises means for periodically determine the position of the vehicle, means for determining a next intersection at which the vehicle (1) will arrive based on the periodically determined position, means for controlling the traffic lights in the next intersection. The control system further comprises means for determining subsequent intersections, which are the intersections at which the vehicle (1) may arrive after passing the next intersection, and means for controlling the traffic lights in the subsequent intersections. Thereby a system is provided wherein no attention to the system is required from the driver of the vehicle (1). Furthermore a green wave of traffic lights is provided when the route of the emergency vehicle (1) is not known in advance.
