为了满足公交线路的动态客流需求，需要确定合理的发车频率；以单条快速公交线路为研究对象，综合考虑乘客出行成本和公交公司运营成本，以系统成本最低为目标建立快速公交发车频率优化模型；并针对模型特点设计了相应的遗传算法进行求解；最后以常州快速公交B22线路为例，对模型进行了应用验证．结果显示，优化后，乘客的候车时间、车内时间分别减少了37．52％、11．6％，乘客的滞留率减少了81．75％，表明该优化模型具有一定的可行性和实用性．

In order to match the dynamics demand of passenger on bus lines ,a reasonable frequency is needed to be determined .Taking a single linear corridor of transit as the research object ,an optimal model for Bus Rapid Transit(BRT) is established ,with the minimization of passenger travel costs and vehicle operating costs as the objective function .In the light of the model characteristics ,genetic algo‐rithm is designed to solve the model .Finally ,Changzhou Bus rapid transit B22 line is exemplified by a case .The results show that passengers’ waiting time、in‐vehicle travel time respectively decreased by 37 .52% 、11 .6% ,passengers stranded rate is reduced by 81 .75% ,w hich indicates feasible and practical of the optimization model .
