本文简述了我国信号交叉口混合交通流特征和研究现状。针对我国典型四相位(双向左转)信号控制交叉口,分析了行人、非机动车以及机动车的运行特征,给出了计算行人和非机动车通行能力的公式和信号控制方法,并结合南京市太平北路—珠江路交叉口的几何尺寸和流量数据进行了计算。计算结果表明,通过设置行人、非机动车专用信号,能够有效避开混合交通流在交叉口的冲突,提高了交叉口的交通安全性及其通行能力。该研究的应用前景较为广泛。
Abstract：The characteristics and the recent researches on signalized intersection with mixed traffic flow in our country is briefly stated. After analyzing the moving features of the pedestrian, non-mobile and mobile at a typical four-phase (bi-left-turning) signalized intersection, formulas for calculating the capacities of pedestrian and non-mobile and a control method are presented in this paper. A calculation example according to the geometry dimension and the traffic flow data of Taiping Beilu-Zhujiang Lu intersection in Nanjing is given. The results show that the conflicts among mixed traffic flows at the intersection is avoided effectively and the traffic capacity and the safety could be enhanced through setting appropriative signal for the pedestrian and the non-mobile. The study is with wide application prospect.
