COMPUTERIZED TRAFFIC SIGNAL SYSTEMS: A FUTURE

THE OBJECTIVE IS TO DISCUSS THE FUTURE OF THE DIGITAL COMPUTER IN TRAFFIC SIGNAL SYSTEMS BY EXAMINING DATA ON SYSTEMS CURRENTLY IN OPERATION. SYSTEMS ARE DESCRIBED, AND SOMETIMES COMPARED FOR NEW YORK CITY, LONDON, BALTIMORE, MD., TORONTO, CANADA, GLASGOW, SCOTLAND, SAN JOSE, CALIF., CHARLESTON, S. C., AND SURFER'S PARADISE, QUEENSLAND. IN ORDER TO ASSESS THE BENEFITS AND COSTS FOR EACH SYSTEM, A SURVEY WAS CONDUCTED. IT WAS FOUND THAT THE SINGLE MOST IMPORTANT BENEFIT OF A COMPUTER CONTROLLED TRAFFIC SIGNAL SYSTEM IS THAT IT OFFERS THE TRAFFIC ENGINEER AN EFFECTIVE AND SAFE MEANS OF CONTROLLING THE TRAFFIC NETWORK. AT THE PRESENT, COSTS FOR THE MOST PART ARE DEPENDENT ON THE DEVELOPMENTS IN COMPUTER HARDWARE AND SOFTWARE.
