摘 要

随着国内经济的快速发展，交通发展速度日益加快，国内公交问题日益增多。在交叉口出现交通堵塞、行人与机动车抢行的现象等交叉口问题普遍出现在国内各个交叉口。而之前通过对城市规划来解决交通问题的方法已无法满足国内迅速增长的交通需求。 此时发展公共交通成为了最好的选择。

而在城市道路网络中，交叉口是交通量的剧集点，也是最容易发生交通拥堵的地方，交通延误主要也是在交叉口发生。因此在交叉口进行公交优先相位控制，能够有效提高公交车通过交叉口的效率，减少交叉口处公交车的时间延误，降低居民出行时间，提高公共服务水平。

本文将以武汉市某一路口为研究对象，对交叉口公交信号优先控制做出分析研究，提出改进方案。结合现有的城市主干道信号协调控制策略，在synchro软件的基础上进行模拟，提出以最大限度降低公交延误为目标的公交优先信号控制方案。

最后在synchro软件的基础上得出时间延误做出比较，综合分析得出结论。仿真结果表明，本轮文所提出的方法在一定的条件下可以减少公交延误，在一定条件下是切实有效的公交信号控制优先方法。

Abstract

With the rapid development of the domestic economy, traffic is accelerating the pace of development, increasing domestic bus. In the intersection there traffic, pedestrians and vehicles to grab the line the intersection problem generally appear in the domestic each intersection. Before the adoption of the method of urban planning to solve the traffic problems has been unable to meet the rapid growth of traffic demand in the country. At this time the development of the public traffic become the best choice.

And in the urban road network, the intersection is series of traffic volume, is also the most prone to traffic congestion, traffic delays but also in major intersections occur. Therefore in the intersection of bus priority phase control, can effectively improve the bus through the intersection efficiency rate, reduce the bus at the intersection of time delay, reduce the residents travel time, improve the level of public services.

The in Wuhan City, one of the intersection as the research object, of intersection traffic signal priority control to make analysis and research, put forward improved scheme. Combined with the existing urban trunk road signal coordinated control strategy, on the basis of synchro software was simulated, and the puts forward to maximally reduce the delay of bus for the goal of the bus priority signal control plan.

Finally on the basis of synchro software to get the time delay to make the comparison, a comprehensive analysis concluded. Simulation results show that the current round of the proposed method under certain conditions can reduce the delay of bus, and in certain conditions is effective bus priority signal control method.

Key words: public transit priority, time delay, signal control, intersection, synchro software
