High-Speed Train Stop-Schedule Optimization Based on Passenger Travel Convenience

Abstract EN

The stop-schedules for passenger trains are important to the operation planning of high-speed trains, and they decide the quality of passenger service and the transportation efficiency.

This paper analyzes the specific manifestation of passenger travel convenience and proposes the concepts of interstation accessibility and degree of accessibility.

In consideration of both the economic benefits of railway corporations and the travel convenience of passengers, a multitarget optimization model is established.

The model aims at minimizing stop cost and maximizing passenger travel convenience.

Several constraints are applied to the model establishment, including the number of stops made by individual trains, the frequency of train service received by each station, the operation section, and the 0-1 variable.

A hybrid genetic algorithm is designed to solve the model.

Both the model and the algorithm are validated through case study.
