Abstract

In the context of high-speed railway marketization, devising a scientific dynamic fare strategy to achieve an efficient match between train supply and passenger demand is a pressing issue. Dynamic pricing and passenger flow assignment were placed into the same framework to achieve collaborative optimization. On the demand side, the space-time service network for the train timetable was constructed. A bidirectional breadth-first reasonable route search algorithm and passenger travel choice cost formula were proposed. The passenger choice behavior parameters were derived from revealed preference (RP) and stated preference (SP) surveys. On the supply side, differentiated train products were classified by the station level and the station number and were connected to the fare adjustment strategy. To solve the comprehensive optimization problem of dynamic pricing and passenger flow assignment, a differential pricing biobjective comprehensive optimization model was developed, and a multidimensional passenger flow assignment strategy was employed. Based on real data, the Beijing–Shanghai high-speed railway was used as a case study, and the station level, OD (Origin-Destination) level, train classification, fare adjustment strategy, enterprise revenue, train indices and OD fare were analyzed. The case study verified the effectiveness of the fare adjustment strategy based on differentiated train products and provided a novel approach for the marketization of high-speed railways.
差别化高铁产品动态定价与客流分配综合优化
在高速铁路市场化的背景下,设计科学的动态票价策略,实现列车供给与客运需求的有效匹配是一个迫切需要解决的问题。将动态定价和客流分配置于同一框架中,实现协同优化。在需求端,构建了列车时刻表时空服务网络。提出了一种双向宽度优先的合理路线搜索算法和乘客出行选择成本公式。乘客选择行为参数来源于显示偏好(RP)和陈述偏好(SP)调查。在供给侧,差异化列车产品按照站点级别和站点数量进行分类,并与票价调整策略相连接。为解决动态定价与客流分配的综合优化问题,建立了差分定价双目标综合优化模型,并采用了多维客流分配策略。以京沪高铁为例,以实际数据为基础,分析了京沪高铁车站层面、始发目的地层面、列车分类、票价调整策略、企业收入、列车指标和OD票价。案例研究验证了基于差异化列车产品的票价调整策略的有效性,为高速铁路的市场化提供了新的思路。

期刊介绍: Transport Policy is an international journal aimed at bridging the gap between theory and practice in transport. Its subject areas reflect the concerns of policymakers in government, industry, voluntary organisations and the public at large, providing independent, original and rigorous analysis to understand how policy decisions have been taken, monitor their effects, and suggest how they may be improved. The journal treats the transport sector comprehensively, and in the context of other sectors including energy, housing, industry and planning. All modes are covered: land, sea and air; road and rail; public and private; motorised and non-motorised; passenger and freight.
