摘　　要：传统的“站站停”轨道交通列车运行模式虽然可以满足乘客的出行需求,但是由于忽略了不同车站客流时空分布的不均衡性,影响了列车运力与乘客需求的匹配效果,造成乘客旅行时间增加、列车运行时间增加等问题。考虑高峰期轨道交通客流的时空分布特性,在描述列车到发时间约束以及精细化刻画客流约束的基础上,以最小化乘客总旅行时间和最大站台人数为目标,本文构建了列车灵活跳站运行整数规划模型,并设计了一种改进的混合蛙跳算法。最后,以北京地铁亦庄线为例验证了模型和算法的有效性。数值结果表明:优化后的列车跳站运行方案减少了乘客总旅行时间,并且最大站台人数也控制在合理的范围之内。虽然列车跳站运行导致复杂的乘客换乘行为,但是只有极少数乘客需要采用换乘方案完成出行。最后,通过对两种需求模式的对比分析,给出了列车跳站运行的适用条件,即客流需求更靠近始发站的需求模式更适合列车跳站运行。Although traditional train all-stop patterns can meet the travel needs of passengers,it ignores the imbalance of passenger flow spatial-temporal distribution in different stations,and thus affects the matching effect between train capacity and passenger demand.Consequently,it leads to more passenger travel time and train running time.Considering the spatial-temporal distribution characteristics of passenger flow during peak hours,aiming at minimizing the total travel time and the maximum number of passengers on station platforms,based on the description of train arrival and departure time constraints and refined passenger flow constraints,this paper proposes an integer programming model of train flexible skip-stop operation,and furthermore designs an improved hybrid shuffled frog leaping algorithm.Finally,the proposed model and its algorithm are verified by the numerical examples of Beijing Metro Yizhuang line.The numerical results show that the train skip-stop operation schemes can reduce the total travel time,and the maximum number of people on the station platforms is also controlled within a reasonable range.Although the train skip-stop schemes lead to complex passenger transfer behaviors,only a few passengers need to use transfers to complete their travel.Through comparative analysis of the two demand patterns,the applicable conditions of train skip operation are given,that is,the demand mode with passenger demand closer to the departure station is more suitable for train skip-stop operation.
