摘　　要：为解决公交系统对路网交通流造成的延误积累问题。分析了公交站点对路段和路网交通流的影响因素和方式,采用多目标优化方法建立了求解设站策略最优解的数学模型,并通过统计分析和遗传算法建立了模型求解算法。研究结果表明:考虑区域路网公交站点服务水平的限制,通过求解公交站点网络规划多目标优化模型确定公交站点设置策略,可有效降低路网交通流平均延误时间。Aiming at the delay accumulation of road network traffic flow caused by public traffic system, the influencing factors and modes of bus station on road section and road network traffic flow are analyzed. The mathematical model for solving the optimal strategy for setting bus stations is established by using multi-object optimization method, and the model solving algorithm is constructed through statistic analysis and genetic algorithm. The research result indicates that considering the restriction of bus station service level of regional road network and solving the multi-object optimization model for bus station network planning to determine the strategy for setting bus stations can effectively reduce the average delay time of road network traffic flow.
