Intercity railway passenger ticket time-sharing pricing method based on generalized cost function

Abstract

The invention provides an intercity railway passenger ticket time-sharing pricing method based on a generalized cost function, and belongs to the technical field of railway transportation service management, and the method comprises the steps: setting an initial ticket price, taking the minimum generalized cost as a target, constructing a passenger flow balanced distribution model, and determiningthe travel time period and travel mode selection of passengers; constructing a time-sharing pricing model taking railway income maximization as a target corresponding to the travel time period and travel mode of the passenger; and solving the passenger flow balanced distribution model and the time-sharing pricing model by adopting a method of combining an inertial particle swarm algorithm and a Frank-wolfe algorithm to obtain a passenger ticket pricing result. According to the invention, the adjusting and guiding effects of the ticket price on the passenger flow are exerted; the passenger flow volume in the peak period is reduced, the passenger flow volume in each period under unified pricing and the passenger flow volume in time-sharing pricing are relatively balanced, the defects that the passenger flow in the peak period is oversaturated and the passenger flow in the valley period is too little and the transportation capacity is wasted are overcome, the traffic pressure is relieved, the intercity railway transportation efficiency is improved, and the resource utilization rate is improved.

Description

technical field [0001] The invention relates to the technical field of railway transportation service management, in particular to a time-sharing pricing method for intercity railway tickets based on a generalized cost function that can transfer passenger flow during peak hours and relieve traffic pressure. Background technique [0002] Intercity railway has played an important role in intercity travel due to its advantages of large volume, fast speed, high frequency, low pollution and comfortable riding environment. However, with the development of intercity high-speed rail, problems such as the uneven distribution of daily passenger flow and the difficulty of regulating passenger flow through single fares are becoming more and more obvious. Intercity high-speed rail serves intercity passenger flow, which is affected by factors such as the degree of social and economic development, urbanization, and population in the channel. There are obvious passenger flow peaks and pass...

AI Technical Summary

Problems solved by technology

The passenger flow is large during peak hours, which brings great pressure to stations and trains. At the same time, part of the passenger flow may be lost due to the limited capacity of passengers' preferred time slots; while the passenger occupancy rate is low during low passenger flow periods, resulting in a large waste of transport capacity
