摘　　要：分析公交车对交通流的影响因素,以兰州市某主干道为例,在社会其他车辆交通量不变,公交车比例不断增加的情况下,分别仿真在该条道路上设置公交专用道和不设置公交专用道2种情况,分析平均总延误、平均停车时间、平均停车次数、平均排队长等参数的变化。仿真结果表明:在其他社会车辆交通量不变的情况下,当公交车交通量达到300veh/h时,可以考虑设置公交专用道。It firstly analyses the influencing factors of buses on tranffic flow, taking a main road in Lanzhou as an example and supposing that the traffic volume of other vehicles is constant and the traffic volume of buses is ever-increasing. The two conditions： setting up bus lanes and being without bus lanes, are simulated and the parameters including the average total delay, the average delay time, the average stop frequency and the average queue are analysed. The results show that if the traffic volume of other vehicles is constant, the bus lanes need to be set up when the bus flow meets 300 veh/h.
