摘要
针对物理网络的客流分配模型难以满足复杂开行方案下精细化客流分析需求的问题,文章提出一种基于开行方案的客流分配方法,将客流分配至列车“交路”层面。首先,解析乘客出行行为复杂化的原因,指出其根源在于列车服务产品由同质化向多样化转变,基于开行方案构建列车服务网络,以刻画列车服务的差异性。其次,基于网络费用流思想,构建以乘客候车时间(节点流费用)及乘车时间(弧流费用)最小化为目标的客流分配模型,并设计标号算法以提高求解效率。最后,以福州地铁F1线与S1线跨线互通运营为背景开展实证分析。结果表明,所构建方法可快速得到不同交路上列车的客流分配结果,满足复杂开行方案下的客流分配需求。同时,模型求解效率较高,具有良好的实用性。该方法可为开行方案设计、客流特征分析、运力运量精细化匹配提供理论支持。
Aiming at the issue that it is difficult to meet the demand for refined passenger flow analysis under complex operation plan with the passenger flow allocation model of physical network,this article proposes a passenger flow allocation method based on operation plan,which allocates the passenger flow to the level of train“routes”.Firstly,it analyzes the reasons for the complexity of passengers’travel behavior,points out that the root cause is the change of train service products from homogenization to diversification,and establishes a train service network based on the operation plan in order to portray the differences of train services.Secondly,based on the idea of network cost flow,a passenger flow allocation model is constructed with the objective of minimizing passenger waiting time(node flow cost)and travelling time(arc flow cost),and a label-setting algorithm is designed to improve the solution efficiency.Last but not least,the empirical analysis is carried out in the context of the through interoperability operation of Fuzhou metro line F1 and S1.The results show that the method established could quickly obtain the results of passenger flow allocation for trains on different routes,meeting the demand of passenger flow allocation under the complex operation plan.Meanwhile,the model solving efficiency is high and has good practicability.The method proposed by this article could provide methodological support for the design of operation plan,passenger flow characterization and fine matching of transportation capacity.
