COMPUTERS TO TALLY TRAFFIC

THREE MINI-COMPUTERS ABOUT THE SIZE OF A WINDOW AIR CONDITIONER ARE NOW IN OPERATION, PROVIDING ACCURATE, UP-TO-THE-MINUTE PICTURES OF TRAFFIC ON URBAN HIGHWAYS IN MICHIGAN, AND NINE MORE WILL BE INSTALLED IN THE NEXT TWO YEARS IN MAJOR CITIES IN SOUTHERN MICHIGAN WHERE TRAFFIC IS HEAVIEST. THE COMPUTERS MONITOR TRAFFIC FLOW BY PICKING UP SIGNALS FROM LOOPS OF WIRE BURIED BENEATH EACH LANE OF A HIGHWAY. THESE LOOPS ALSO SERVE FOR TRAFFIC SIGNAL CONTROL PURPOSES. THE VEHICLE COUNT IS STORED IN THE COMPUTER AND PERIODICALLY TRANSMITTED BY TELEPHONE LINE TO A CENTRAL COMPUTER IN LANSING. TRAFFIC ENGINEERS CAN OBTAIN THE LATEST TRAFFIC COUNTS BY DAILING A NUMBER. EACH COMPUTER CAN SCAN UP TO 16 DIFFERENT HIGHWAY LOCATIONS, MAKING THE SYSTEM LESS EXPENSIVE TO OPERATE THAN THE 16 MANUALLY ATTENDED COUNTERS THEY REPLACE.
