无公交专用道下的单点公交优先控制

Bus Priority Signal Control for Signalized Intersection without Bus Lane

在无公交专用道交叉口情况下,根据公交车到达检测器时刻、检测器布设位置及交通流量等参数,预测出公交车前方车辆数及车辆消散时间,以公交车延误最小为优化目标建立了公交优先信号配时参数优化模型。利用Vissim仿真软件对文中提出的控制方法进行了模拟仿真,结果表明:该控制方法能够为公交车准确提供优先配时方案,有效减少了无公交专用道交叉口的公交车延误。

Firstly,this paper forecast the vehicle number before the bus and their dissipation time according to the time bus trigger bus detector,bus detector location and other traffic parameters based on intersection without bus lane.Then,the dissipation time was used to optimize the signal timing parameters for bus priority in order to reduce bus delay.Vissim simulation software was used to simulate the proposed control method.The result indicates that this control method can provide exact signal priority scheme for bus and reduce bus delay effectively for intersection without bus lane.
