摘　　要：末班车衔接优化中难于协调的两个关键因素是最大限度减少换乘乘客等待时间和尽可能避免乘客换乘失败.针对末班车时段,重点考虑乘客对换乘满意度的差异化感知,分析换乘站乘客换乘过程及列车接续过程.选取各线路末班车时段内第一趟列车的发车时间为决策变量,以乘客换乘感知费用总和最小为目标,构建全网条件下末班车时段多趟列车的时刻表衔接优化模型,设计多种群遗传算法进行求解.以成都市轨道交通网络为例,对模型及算法进行应用与验证.结果表明:与现有的轨道交通末班车衔接方案相比,通过采用本文提出的模型及多种群遗传算法,成功换乘客流量增加了3.1%,乘客换乘感知费用总和减少了29.7%,有效提高了末班车时段列车接续效果,为网络化运营组织提供重要依据.There are two key factors in the connecting optimization of last train that are difficult to coordinate.They are minimizing the waiting time for transfer passengers and avoiding the failure to transfer as far as possible.Passengers’differential perception of transfer satisfaction during the last train period is stressed to analyze the transfer process of passengers and connection process of trains at a transfer station.To minimize the sum of passengers’transfer perception cost,a model of schedule connecting optimization in the last train period of the whole network is constructed.The model takes the first train departure times of each rail line during the last train period as decision variables and designs a multiple genetic algorithm to solve it.Then,Chengdu’s rail transfer network is taken as an example to apply and verify the model and algorithm.The results show that compared to current connecting scheme,the number of passengers successfully transferred has increased by 3.1%,while the sum of passengers’transfer perception cost has decreased by 29.7%by using the proposed model and algorithm,which can effectively improve the connection effect during the last train period,and lay important basis for improving the network operation.
