摘　　要：为了研究信号交叉口各交通流的相互影响,以便对其进行更为合理有效的信号控制,分析了四路平面信号交叉口的交通流冲突,并应用接受间隙理论,通过实际观测数据得到了左转非机动车穿越分布规律,推导了左转非机动车穿越数及滞留数计算公式;通过定量分析,最后得到了左转非机动车对直行机动车的影响模型,为设置非机动车专用信号相位提供了理论依据,同时为信号交叉口的信号设计,特别是非机动车专用信号相位的设置、分析和研究提供了新思路和新方法。In order to research the influence in the traffic flows and make more reasonable and more efficient control in signalized intersection, authors analyzed the conflict in the four cross signalized intersection. With the application of the theory of the gap acceptance for passing through, authors gained the chorological discipline of the left turn non motors by the observable data. And the formula of the number of the passing through and the detained non-motors were deduced. By the quantitative analysis,the analysis model of left-turn non-motors influence in the straight motor was set up. The results provide the theoretical basis to the foundation of installing the appropriative non-motor phase, and supply the new ideas and methods to the signal design, especially the non-motor phase setting in signalized intersection.
