Optimization Strategy of Arrival and Departure Tracks Distribution in China Railway Highspeed Express Based on Lateral Transshipment Between Trains

Railway highspeed rail express transportation has become a current hotspot, and its operation will inevitably have an impact on the current highspeed rail passenger transport organization. Therefore, this article takes highspeed railway stations as the research object, fully considering the resources of the section, throat area, arrival and departure tracks, and the lateral transshipment demand of China railway highspeed express, constructs a space-time network for the station. With the shortest delay time of highspeed rail passenger trains as the optimization goal, a 0–1 integer programming model is established. A case study is designed and solved using CPLEX to verify the effectiveness of the model and achieve a reasonable distribution of stations to arrival and departure tracks.
