随着经济和社会的发展进步,我国城市化进程步伐加快,城市交通需求与土地资源供给之间的矛盾日益突出,交通拥堵问题严重影响人们的生活.公交优先是缓解城市交通拥堵的主要策略之一.本文以长春市以某交叉口为例进行了实证分析,得出改进后的交叉口公交优先信号配时方案,仿真结果表明,基于公交优先交叉口的信号配时方法是缓解交通拥堵问题的有效途径之一.%With the development of economy and society, the urbanization process of China is speeding up, the con-tradiction between urban traffic demand and land resources supply is becoming increasingly prominent, the traffic jam problem seriously affects people"s life. Bus priority is one of the main strategies to ease urban traffic conges-tion. Taking Changchun city as an example, this paper makes an empirical analysis, and obtains the improvement of bus priority signal timing scheme. The simulation results show that the method of signal timing based on bus priority intersection is one of the effective ways to alleviate traffic congestion.
