SYNCHROGREEN REAL-TIME ADAPTIVE TRAFFIC CONTROL SYSTEM SEMINOLE COUNTY DEPLOYMENT

摘要

SR 436 (Altamonte Drive), between Westmonte Drive and Maitland Avenue, is a 1.7 mile roadway segment in Seminole County, Florida. This corridor includes 12 traffic signals and is a minimum six lane roadway section. This corridor presents a number of challenges with respect to traffic signal coordination, which are not easily overcome using conventional traffic signal timing principles. High pedestrian volumes crossing SR 436 and emergency vehicle pre-emption calls frequently caused traffic controllers to enter transition mode. Seminole County staff, over the years have adjusted the signal timing on SR 436 in response to changing traffic conditions through routine maintenance and retiming studies. Despite these adjustments, the unpredictable nature and day-to-day fluctuation on this corridor are not conducive to actuated-coordinated operations.
