基于Synchro Studio的行人专用相位仿真研究

基于Synchro Studio软件包对饱和交叉口进行了仿真分析,对有、无行人专用相位带来的车辆延误进行了对比。分析数据表明,当交叉口交通状况处于饱和状态时,行人专用相位对交叉口影响很大。取消行人专用相位后,各方向车辆延误大幅减小,交叉口服务水平显著提高。研究表明,对于饱和交叉口,在其它改善措施难以实施的情况下,取消行人专用相位对提高交叉口通行能力、缓解交通拥堵是非常有效的。

Synchro Studio-based Simulation of Pedestrian Exclusive Phase

Based on simulation of over-saturated intersection with the software package of Synchro Studio, vehicle delay comparsion was analyzed before and after set pedestrian phase. Analysis of data shows that pedestrian phase affects traffic greatly at the over-saturated intersection. The vehicle delay from every direction woluld decrease largely and the Level of Service at the intersection would improve obviously if pedestrian phase was removed. The results reveal that it is effectively to enhance intersection capacity and alleviate traffic jam to cancel the pedestrian phase when there is no other method to improve the transportation at intersection under over-saturated situation.
