The Traffic Signal Control Method and Applicable Condition of U-Turn in Urban Arterial Road

摘要

In order to improve the low traffic efficiency at intersection caused by concentrated traffic conflict in Chinese urban road, the traffic signal-coordinated control method between median opening and intersection is proposed from the view of space-time resources optimization, and the road conditions and traffic conditions suitable for the U-turn in urban arterial road are analyzed. The intersection of Yangtze River road and Songshan road in Harbin is taken as an example, VISSIM simulation results show that the cycle, average delay, queue length, and waiting time of pedestrian crossing roads at the intersection decrease significantly after the application of U-turn and traffic signal-coordinated control method, which effectively verify the feasibility of the method. The method is beneficial to the traffic signal-coordinated control among urban arterial road.
