Abstract

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
