两相位信号交叉口左转交通流延误模型的研究

左转车是信号控制交叉口产生冲突点最多的车辆，因此对左转交通流的延误分析是研究交叉口延误的基础。文中在研究改进的HCM延误模型基础上，考虑了左转车流驶离交叉口时非机动车驶入机动车道从而造成左转车流的跟驰延误，结合我国交叉口左转交通流的特性，建立了一个两相位信号交叉口左转交通流延误模型，并通过实例说明了此模型的有效性和适用性。

Study of a Model for Left-turn Flow Delay at Two-phase Signalized Intersection

The left-turn flow is the bottleneck that leads to the traffic conflicts(congestions) at the signalized intersection;therefore,analyzing left-turn flow delay is the foundation of studying intersection delay.Based on the existing HCM delay model,and with the consideration of non-motorized vehicle block interference which causes the follow delay of left-turn flow when the non-motorized vehicles get into motorized vehicle lane,a new model was established for the left-turn flow delay at two-phase signalized int...
