EFFECT OF AN EXPRESSWAY ON DISTRIBUTION OF TRAFFIC AND ACCIDENTS

RESULTS ARE SUMMARIZED OF A TEST OF THE EFFECT OF AN EXPRESSWAY ON THE TRAFFIC FLOW AND ACCIDENT EXPERIENCE ON ALL STREETS IN AN AREA. THE STUDY IS BASED ON AN EXAMINATION OF TRAFFIC VOLUME AND REPORTED MOTOR VEHICLE TRAFFIC ACCIDENTS BEFORE AND AFTER AN EXPRESSWAY IS CONSTRUCTED AND OPENED. CHANGES IN TRAFFIC VOLUME ON SEGMENTS OF THE ARTERIAL SYSTEM WERE DETERMINED AND ARE PRESENTED IN THE FORM OF A PLUS AND MINUS FLOW MAP. THIS MAP REFLECTS THE EFFECT OF THE EXPRESSWAY ON EAST-WEST ARTERIAL STREETS, AND THE EFFECT OF EXPRESS-WAY RAMPS ON NORTH-SOUTH ARTERIALS THE AVERAGE DAILY TRAFFIC IS DISTRIBUTED BY HOURLY INCREMENTS TO MEASURE THE ABILITY OF THE EXPRESSWAY TO REDUCE CONGESTION ON ARTERIALS DURING THE PEAK HOURS OF VEHICULAR TRAFFIC TRAFFIC. THIS STUDY ALSO MEASURES THE EFFECTIVENESS OF HIGHWAY PLANNING IN REDUCING THE NUMBER OF MOTOR VEHICLE TRAFFIC ACCIDENTS.
