摘要: 为合理分配突发公共卫生事件下高速铁路的客流,结合高速铁路物理网络及开行方案,构造高速铁路列车服务网络,将旅客出行的广义费用分为时间成本、票价支出和拥挤成本,从而确定高速铁路旅客出行广义费用计算方法,并将其作为出行阻抗;以旅客广义出行费用最小为目标建立客流分配模型,基于相继平均法(MSA)的改进算法求解该模型;利用Matlab编程,以武汉地区发生突发公共卫生事件为例,验证模型与算法的合理性。研究结果表明:突发公共卫生事件条件下高速铁路部分列车上座率较高或较小,可采用增开、减少列车的开行次数和调整列车的停站方案,使列车的上座率更合理。

Abstract: In order to reasonably allocate passenger flow for high-speed railway under public health emergencies, a train service network was constructed considering physical network and operation plan of high-speed railways. Generalized expenses of passenger travel were divided into time cost, fare expenditure and congestion cost before its calculation method was determined, and it was defined as travel resistance. Then, a passenger flow distribution model was established with minimizing generalized travel cost as its goal, and was solved by an improved algorithm based on method of successive averages(MSA). Finally, Matlab programming was utilized to verify rationality of the model and algorithm with incidents in Wuhan as an example. The results show that occupancy rate of some high-speed railway trains is extremely high or large under conditions of public health emergencies, and it can be made more reasonable by increasing or reducing number of trains and adjusting stations' stop plan.

Key words: public health emergency, high-speed railway, passenger flow assignment, time cost, fare expenditure, congestion cost
