摘　　要：高速铁路客流分配过程的本质是旅客购票过程,影响旅客购票过程的主要因素包括铁路售票策略和旅客购票时序。本文将铁路售票策略和旅客购票时序嵌入到客流分配过程中,设计了针对不同售票策略的换乘网络,根据不同OD行程的购票特征构造购票强度函数;利用若干最小费用换乘方案构建屋顶模型,将时变需求的连续出行时间离散化,获得每一个最小费用方案的离散出行客流量,设计了考虑售票策略的高速铁路客流分配方法。通过对京广深高速铁路客流分配实例分析表明,客流分配结果与旅客实际购票过程相吻合,运算时间短,证实了配流方法的有效性,具有解决大规模高速铁路网络客流分配能力,为列车运行图和售票策略提供评价手段。The substance of passenger flow assignment for high-speed railway is the process of ticket-booking by passengers,which is influenced by ticket strategies and the ticket-booking order of passengers.This paper integrated the ticket strategies and the ticket-booking order into passenger flow assignment method,designed transfer networks for diverse ticket strategies,and constructed ticket-booking intensity functions based on the ticketing characteristics of different OD trips.The rooftop model was constructed by several transfer plans with minimal costs,which can discretize the continuous travel time of time-varying demand and obtain the passenger flow choosing each plan.The passenger flow assignment method was proposed for high-speed railway based on ticket strategies.The case study of Beijing-Guangzhou-Shenzhen high-speed railway indicates that the results fit the real ticket-booking process of passengers,and the short calculation time demonstrates the effectiveness of the method,which is able to address the passenger flow assignment problem for a large-scale high-speed railway network,and provide evaluation for train working diagrams and ticket strategies.
