EFFECT OF TRAFFIC IMPROVEMENTS ON OPERATION OF AN URBAN ARTERIAL STREET

METHODS WERE EVALUATED TO INCREASE THE TRAFFIC CARRYING CAPABILITY OF IMPROVED ARTERIAL STREETS. ESSENTIALLY, THE IMPROVEMENTS CONSISTED OF THE REMOVAL OF STREETCAR AND LOADING PLATFORMS, NEW PARKING AND TURN REGULATIONS, AND CHANGES IN THE TIMING OF SIGNALS. RESULTS OF BEFORE AND AFTER STUDIES INDICATED THAT (1) OVER-ALL PEAK HOUR VOLUMES FOR FOUR SECTIONS INCREASED 11%, 27%, 11%, AND 9% RESPECTIVELY, (2) THE GENERAL TREND WAS TOWARD A SMALL INCREASE IN PERCENT LOADED CYCLE TIME, (3) THE AVERAGE SPEED FOR ALL RUNS INCREASED FROM 17.8 MPH TO 19.2 MPH, (4) RUNNING SPEEDS INCREASED FROM AN AVERAGE OF 21.8 MPH TO 22.8 MPH, (5) THE CAPACITIES OF THE FOUR SECTIONS ALSO INCREASED.
