  针对城市主干道与主干道相交的A类交叉口内,左转公交与其它交通混合行驶时出现的问题,本文提出一种A类交叉口优化模型。模型采用四相位的配时方法,通过设置两条公交与社会车辆分别行驶的左转车道的方式,使冲突分离,并通过VISSIM仿真软件,结合具体实例进行仿真检验优化模型的适用性。

AbstractAn optimization model was presented based on the issue of left-turn bus mixed with other traffic vehicles in the urban Class-A intersection which was intersected by two arterial roads. With four-phases timing method and the way of setting the two left-turn lanes to drive the bus and social vehicles separately in the model, the conflict could be reduced. Finallythe adaptability of the optimization model was test by a specific example’s simulation using VISSIM simulation software.
