Study on Benefit Analysis and Setting Condition of Signal Control Right-Turn Vehicles at Intersection

Based on the analysis of conflicts among non-motor vehicles, pedestrians crossing the street, right-turn vehicles traffic at a signalized intersection, and the signal control right-turn vehicles was proposed to alleviate the traffic conflicts. As an example, the intersection of Nanjing Road and Weijin Road in Tianjin is investigated. According to the real traffic flow characteristics of this intersection to set the exclusive right-turn phase, taking evaluation analysis on traffic benefit of signal control right-turn vehicle at intersection east entry and combining verification analysis with Vissim simulation, the results show that the countermeasures are reasonable and feasible. By changing the parameter value in the Vissim model building, it gets a signal control critical flow value to alleviate the conflict among the non-motor vehicles, pedestrians, and right-turn vehicles, which enables to improve the operation efficiency of the signalized intersection.
