摘要

针对城市道路单进口放行方式下的信号控制交叉口,为有效利用时间资源,减少机动车与非机动车、行人之间的冲突,提出一种基于多属性决策理论的信号相位相序优化方法。首先利用行人二次过街方案设置原理,在不改变机动车主相位的前提下设计出行人信号嵌套相位;然后建立交叉口混合交通信号相位相序多属性决策模型,拟选取最优信号相位相序方案;最后,使用Vissim5.0仿真软件对南宁市秀灵秀厢交叉口进行仿真,并与非嵌套相位以及嵌套相位下各相位相序方案相比较。仿真效果表明:该方法可行有效,其选出的最优方案较无嵌套相位方案,车辆平均延误、行人平均延误分别减少了60.0%和31.1%,交叉口通行能力、人行横道通行能力分别增加了2.4%和14.7%,有效提高了交叉口通行效率。

Abstract

For signalized intersection of urban road under signal design mode of one-phase-one-approach, a phasing-sequence method based on multiple attribute decision-making theory was proposed to use the time resource effectively and reduce the conflict between motor vehicles and slow mode transportation. Firstly, by using the principle of pedestrian twice crossing street, the pedestrian nested signal phase was designed without changing the main phase of motor vehicles. Then, the phasing-sequence multiple attribute decision-making model was provided to get the best plan of signal phase. Finally, the isolated intersection between Xiuxiang Road and Xiuling Road in Nanning City was carried out simulation via software Vissim5.0. The phasing-sequence plans of non-nested signal phase and nested signal phase were compared. The result shows that the proposed method is feasible and effective. The vehicle average delay and pedestrian average delay of the best plan of signal phase by this method are decreased by 60.0% and 31.1%, the intersection capacity and crosswalk capacity are increased by 2.4% and 14.7%, compared with the non-nested signal phase. It can effectively improve the traffic efficiency of intersections.
