A LOCAL TRAFFIC CONTROL POLICY WHICH AUTOMATICALLY MAXIMISES THE OVERALL TRAVEL CAPACITY OF AN URBAN ROAD NETWORK

Traffic control strategy is proposed which causes the traffic to be distributed in the spare capacity available on the network so that the traffic uses junction space economically. The policy requires only local information such as traffic flows and queue lengths, which can be obtained from vehicle detectors. Origin-destination information is not required. Consequent changes in the traffic pattern are automatically taken into account. It is assumed that traffic signals control all substantially congested junctions, and that, at the most congested junctions, conflicting streams of traffic do not filter through one another. The signals must insulate a traffic stream from a conflicting stream by use of non-overlapping greens. It is assumed that queue-storage capacity is not limited. It is also assumed that a driver only changes his route to a quicker one, and will continue to do so if such a route becomes available.
