Abstract

AS AN EXTENSION OF THE WORK CARRIED OUT BY CAMKIN AND LOWRIE (1972), AN INVESTIGATION INTO APPROXIMATELY 15000 ACCIDENTS WHICH OCCURRED ON EIGHT CO-ORDINATED TRAFFIC SIGNAL SYSTEMS IN THE PERIOD BETWEEN THE FIRST QUARTER OF 1968 AND THE THIRD QUARTER OF 1974 WAS UNDERTAKEN. THE AIM OF THIS INVESTIGATION IS TO MEASURE THE EFFECT CO-ORDINATION HAD ON TRAFFIC ACCIDENTS WITHIN THESE CO-ORDINATED TRAFFIC SIGNAL SYSTEMS. A 20 PER CENT IMPROVEMENT IN THE TOTAL NUMBER OF ACCIDENTS OCCURRING WITHIN THE SYSTEMS WAS OBTAINED. THE MAJOR IMPROVEMENTS OCCURRED IN PEDESTRIAN-INVOLVED AND RIGHT-ANGLE ACCIDENTS. THESE IMPROVEMENTS OCCURRED WITHOUT ANY SIGNIFICANT CHANGE IN ANY OTHER ACCIDENT TYPE. WHEN EXISTING SITES WERE CO-ORDINATED THERE WAS A SIGNIFICANT IMPROVEMENT IN RIGHT-TURN ACCIDENTS. THEREFORE, IT WAS CONCLUDED THAT THE CO-ORDINATION OF TRAFFIC SIGNALS CAN ALLEVIATE ONE OF THE MAJOR DISADVANTAGES OF ISOLATED TRAFFIC SIGNALS. (A). FOR THE COVERING ABSTRACT OF THE CONFERENCE PROCEEDINGS SEE IRRD ABSTRACT NO. 226354.
