PLATOON PROFILES AND LINK DELAY FUNCTIONS FOR OPTIMAL COORDINATION OF TRAFFIC SIGNALS ON ARTERIAL STREETS

AN OPTIMAL SCHEME FOR COORDINATION OF CONSECUTIVE SIGNALS ALONG ARTERIAL ROUTES OR NETWORKS REQUIRES A MICROSCOPIC ANALYSIS OF THE TRAFFIC FLOW PATTERNS ON EVERY LINK OF THE SYSTEM. SUCH AN ANALYSIS WAS CARRIED OUT FOR TWO-WAY LINKS ON A MAJOR ARTERY IN DOWNTOWN TORONTO. ACCURATE PLATOON PROFILES WERE OBTAINED VIA THE DIGITAL COMPUTER SYSTEM CONTROLLING THE TRAFFIC LIGHTS THROUGHOUT THE METROPOLITAN AREA AND ITS ASSOCIATED VEHICLE DETECTOR SYSTEM. INDIVIDUAL LINK DELAY FUNCTIONS WERE CALCULATED SUBJECT TO THE PARTICULAR CHARACTERISTICS OF EACH SIGNALIZED TRAFFIC LINK. THESE FUNCTIONS WERE THEN COMBINED IN PARALLEL ACCORDING TO THE PRINCIPLES OF THE TRRL COMBINATION METHOD. THE OPTIMAL SETTINGS DERIVED THEREUPON ARE SHOWN TO DEVIATE SUBSTANTIALLY FROM THOSE ESTABLISHED BY CONVENTIONAL COORDINATION METHODS. THE RESULTANT IMPROVEMENT IN DELAY TO TRAFFIC WAS CONFIRMED BY DIRECT FIELD OBSERVATIONS.
