Abstract
The present disclosed subject matter relates to a method of controlling event-responsive traffic lights at an intersection of lanes by a controller which switches the traffic lights in a sequence of phases. The controller has a memory storing a set of phase sequences and is configured to change from one phase sequence to another. The method comprises, in a server: a) generating candidate sets of phase sequences; b) determining the traffic flows on the lanes; c) calculating a cost measure for each candidate set; and d) sending the candidate set with the lowest cost measure to the controller; in the controller, receiving and storing the sent set in the memory as the set; and repeating steps b)-d). The disclosed subject matter further relates to the server used in said method.
