【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。更多还原

【Abstract】 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.更多还原
