交叉口单点公共汽车交通优先控制方法研究

Study on the Bus Priority Signal Control Theory of Single Intersection

开发ITS背景下的公共汽车交通优先控制方法是从根本上改善公交车辆运行情况的需要。满足车辆固有的行驶时刻表是实施公交优先通行申请的重要依据,在本文控制策略中运用绿灯时间延长和相位提前激活两种方法,在兼顾其它车辆运行情况的前提下,给予晚点公交车优先的通行信号。论文最后以厦门市湖滨南路实际交通流量为依托,运用交通仿真方法验证了优先控制策略的实际效果。

Bus priority signal control on the background of ITS is to improve bus operation. In the control strategy, the basic reason to give bus priority is to keep the bus on schedule, so the system only gives priority signal to the bus fallen behind schedule by green extension and red truncation, concurrently taking consideration of other traffic. The control theory is applied in a real project in Xiamen and is proved to be effective through the simulation of VISSIM.
