A METHOD FOR ADAPTIVE TRAFFIC CONTROL

PRESENT METHODS FOR DETERMINING OPTIMAL SETTINGS FOR SIGNAL NETWORKS ARE TOO TIME CONSUMING TO BE IMPLEMENTED ON-LINE WITH CONTEMPORARY COMPUTERS. THE BULK OF HTE COMPUTATION INVOLVES SIGNAL COORDINATION BETWEEN INTERSECTIONS. IT IS PROPOSED THAT GLOBAL SIGNAL COORDINATION MAY BE ACHIEVED ADAPTIVELY USING APPROPRIATELY CHOSEN LOCAL CONTROL ALGORITHMS. THIS IS DEMONSTRATED FOR CERTAIN SIMPLE NETWORKS USING AN ALGORITHM THAT MINIMIZES STOPS TO VEHICLES IN PLATOONS. THE RESULTS ARE VALID FOR ESSENTIALLY LIGHT TRAFFIC. FOR SEVERAL CASES IT IS SHOWN THAT A SYSTEM CONSISTING OF SIGNALS CONTROLLED INDEPENDENTLY WITH THE ALGORITHM CONVERGES TO A PERIODIC ASYMPTOTIC STATE EXHIBITING GLOBAL SIGNAL COORDINATION. THE CONVERGENCE PROOF IS SIMULTANEOUSLY A PROOF OF THE SYSTEM'S STABILITY. NO CLAIM IS MADE THAT THE PARTICULAR ALGORITHM STUDIED HERE IS SUITABLE FOR IMPLEMENTATION IN THE FIELD. /AUTHOR/
