摘要： 快速公交是解决城市交通问题的有效手段，公交信号优先对于提高快速公交运营效率具有重要作用。具备公交优先功能的快速公交沿线路口协调控制有较高的复杂性，为此，本文提出了一种关键参数抽取方案，针对快速公交全线路路口信号优先控制，给出了定周期下优先感应控制方案和优先评估体系，通过分时段遗传算法实现了信号控制参数与车辆调度参数的协调优化，达到了公交优先与社会车辆理想通行的综合最优控制效果，以北京市南中轴BRT为例，应用VISSIM交通软件进行仿真，通过与其它多种控制方案优先效果的比较，验证了本文方案良好的控制效果。

Abstract: Bus rapid transit (BRT) is an effective way to improve urban traffic status. Traffic signal priority is an important technique to increase the efficiency of BRT. In view of complexity of coordinated control with signal priority, this paper presents a strategy of key parameters selection, a control method of signal priority based on fixed period and a priority appraising system. Optimization of signal control parameters and bus dispatch parameters is realized using genetic arithmetic for different periods to obtain general control effect of BRT and other vehicles. Compared with several other control methods, priority effect of this method is demonstrated by the VISSIM simulation of the Beijing South-Center Corridor of China.

Key words: bus rapid transit (BRT), traffic signal priority, coordinated control, genetic algorithm, VISSIM
