摘　　要：社区公交是一种衔接轨道交通、方便乘客“最后一公里”出行的微循环公交形式。考虑同时减少乘客出行时间和社区公交企业运营成本,提出社区公交线路及发车频率协调优化的双目标优化模型,并设计了两阶段改进NSGA-Ⅱ算法求解模型。以重庆市观音桥组团为例,调查组团内的社区公交线路及站点,并采用上述模型与方法对观音桥组团内的社区公交线路进行优化,优化结果与调查结果相比较,发车频率由原来最高的7.5辆/h提升到15.27辆/h,优化后的线路更能满足乘客的出行需求,证明了提出的模型和方法的有效性,能够对于社区公交网络设计和时刻表编制提供参考。Community bus is a kind of microcirculation bus that connects rail transit and facilitates passengers to travel"the last kilometer".Considering the simultaneous reduction of passenger travel time and the operating cost of community bus enterprises,the two-target optimization model of community bus line and departure frequency is proposed,and the two-stage improved NSGA-Ⅱalgorithm solution model is designed.In Chongqing Guanyinqiao group,for example,the survey group of community bus lines and site,and adopt the model and method of group of community bus line optimization,optimization results compared with the survey results,departure frequency from the highest 7.5 to 15.27 car/h,optimized lines can meet the demand of passengers travel,proved the effectiveness of the model and method,can for community bus network design and schedule to provide reference.
