Early Green Start Analysis for Time-of- Day Signal Coordination

摘要

This article includes a practical approach to developing and maintaining reliable time-of-day coordination between traffic-actuated signals. The early sync phase green phenomenon associated with these signals during coordination causes the quality of signal progression to vary from cycle to cycle. The technique includes examining real-time data information on the effectiveness of current coordination plans for traffic-actuated signals and using this information to simulate existing signal progression conditions on an average basis. Opportunities to expand average bandwidths also are identified.
