针对路段上交通流的特性,以及信号交叉口交通流的动态流通特征,分析了车辆到达信号交叉口的规律以及车辆越过停车线的特点,从而建立了停车延误模型;又分析了单个相位停车线的长度与交叉口几何特征的关系,及车辆在通过信号交叉口之间的路段过程中的运行特性,建立了相位延误模型;从而得到一个在信号交叉口处适用任何饱和度的排队延误模型,使得结果更贴近车辆在信号交叉口的实际延误时间.
In view of the characteristics of traffic flow in the road section and the dynamic flow characteristics of the traffic flow at the signalized intersection, the law of the vehicle arriving at the signalized intersection and the characteristics of the vehicle crossing the stop line are analyzed, and a parking delay model is established. The relationship between the length of the intersection and the geometric characteristics of the intersection and the characteristics of the vehicle running through the road section between the signalized intersection have been established. The delay model of the queuing system with any saturation applied at the signalized intersection is obtained, The result is closer to the actual vehicle delay at the signalized intersection.
