ANALYSIS OF ROAD USER ECONOMY BEFORE AND AFTER TRAFFIC SIGNAL INSTALLATION AT A T INTERSECTION

A COMPARISON WAS MADE OF ROAD-USER AND TRAFFIC CONTROL COSTS BEFORE AND AFTER A STOP SIGN ON A CONNECTING STREET TO A MAIN THOROUGHFARE WAS REPLACED WITH A TWO-PHASE TRAFFIC SIGNAL. COMPARISON WAS MADE BY COMPUTING TOTAL ANNUAL USER COSTS INCURRED BY VEHICLES FROM STOPPING, WAITING, AND REGAINING SPEED UNDER THE TWO FORMS OF CONTROL. THIS INCLUDED ANNUAL USER RUNNING COSTS (STOPPING AND IDLING), ACCIDENT COSTS, AND USER TIME COSTS (FOR STOPS AND FOR IDLING). COSTS OF THE TRAFFIC CONTROL SYSTEM WERE INCLUDED IN THE ANALYSIS; CAPITAL COSTS OF CONTROL SYSTEM AND ANNUAL MAINTENANCE AND OPERATING COSTS. EVEN WITHOUT ROAD-USER TIME COSTS, THE RESULTS INDICATED A SUBSTANTIAL INCREASE OF ROAD-USER COSTS AS A RESULT OF SIGNALIZING THE INTERSECTION.
