摘　　要：通过分析国内外对BRT车辆优先已有的研究成果,介绍信号交叉口BRT车辆主动优先技术中绿灯延长和红灯早断方法。基于对BRT优先通行控制方法的研究,结合兰州市BRT1号线和费家营十字交叉口的实际调查,通过交通仿真软件VISSIM对交叉口现状进行仿真,得到交叉口的各项评价指标,如延误、排队长度以及行程时间等。并在现状基础上,通过设置BRT主动优先方式,其中包括绿灯延长和红灯早断,来分析交叉口交通运行评价指标的变化情况。This research aims at the single intersection, on the basis of existing research results of BRT system at home and abroad, mainly introduces the green extension and red light in the active priority technology early method. BRT priority control method based on this research results, combined with the actual investigation of Lanzhou City BRT1 lines and Feijiayingshizi intersection, to simulate the status quo through traffic simulation software VISSIM, the evaluation index of intersection, such as delay, queue length and travel time etc.. And in the present situation foundation, by setting the priority mode different BRT signals,including the extension and the red light off early, to analyze the change of traffic intersection evaluation index.
