Title: A METHOD OF MEASURING RELATIVE EFFICIENCY OF TRAFFIC FLOW THROUGH STREET INTERSECTIONS
Abstract: TRAFFIC COUNTING AT URBAN INTERSECTIONS IS A MEANS OF MEASURING TRAFFIC FLOW AND DELAY, THE LATTER BEING DEFINED AS THE RATIO OF CARS DELAYED DURING A GIVEN PERIOD OF TIME TO THE TOTAL NUMBER PASSING THROUGH THE INTERSECTION. TEN INTERSECTIONS IN BALTIMORE AND WASHINGTON, D.C., WERE INVESTIGATED TO TEST THE EFFECT OF FOUR SETS OF VARIABLES (ONE-WAY/TWO-WAY STREETS, SIGNALIZED/UNSIGNALIZED INTERSECTIONS, POLICE CONTROL/NO CONTROL, AND PEDESTRIAN VOLUME) ON DELAY AT INTERSECTIONS. CHARTS ARE PRESENTED DESCRIBING THE RESULTS. IT IS CONCLUDED THAT SYNCHRONIZED SIGNALIZED INTERSECTIONS ARE AN ACTIVE MEANS OF PROMOTING TRAFFIC FLOW, NO CONTROL IS PREFERABLE TO OFFICER CONTROL FROM A VEHICULAR STANDPOINT, AND WHERE PEDESTRIANS ARE USING AN INTERSECTION IN LARGE NUMBERS, THE BEST TO HOPE FOR IS 60--70% DELAY.
