摘　　要：研究基于多交路共线运营列车开行方案的客流分配问题,有利于分析评价列车开行方案编制质量,评估列车运输资源的负荷均衡性。本文选取典型城市轨道交通多交路共线运营列车开行方案,构建基于列车开行方案的共线运营服务网络。考虑乘客在共线区段的路径选择行为,提出轨道交通共线问题的数学模型。通过将客流加载的有效路径求解问题转化为求解共线运营服务网络的最短超路径问题,提出基于发车频率的超路径客流分配方法,构建多交路共线运营服务网络客流分配模型,并提出求解配流模型的混合连续平均算法。算例研究表明,由配流结果计算所得的断面满载率相对偏差最大为4.54%,可以实现运量与列车运力的较好匹配;相同服务频率下,多编组模式下的列车最大断面满载率较单一编组模式下的最大断面满载率低15.64%,多编组开行方案的客流适应性更强。本文方法可为复杂交路设计、列车开行方案编制及优化调整提供依据。The research on the passenger flow assignment based on the train plan with multi-routing operation is beneficial to analyze and evaluate the quality of train plan,assess the load equalization of train transportation resources.This paper analyzes the typical train plan with multi-routing common-line operation of urban rail transit and develops a common-line operation service network based on the typical train plans.The paper proposes a mathematic model of common-line problem considering the passengers'route choice behavior in the common-line sections.A frequencybased assignment model of hyperpath is developed by transforming the solution of effective paths loading the passenger flow into the shortest hyperpath problem of the service network.Furthermore,an equilibrium passenger flow assignment model for common-line operation mode with multi-routing is developed,along with a successive averages mixed algorithm to solve the model.The results of the numerical example show that the maximum relative difference of load factor is 4.54%,which indicates the passenger volume is well matched with train capacity.Under the same service frequencies,the maximum section load factor of the multi-formation mode is 15.64%,which is lower than that of the uniform formation,and the passenger flow adaptability of multi-formation train plan performs better than that of uniform formation.The proposed method can provide the basis for complex routing design and train plan optimization for the urban rail transit.
