Abstract:

We address track utilization of highspeed railway station for a definite train diagram and station hall layout. We analyze the number of ticket entrance nearby fixed seats and passage distance between ticket entrance and platform with compatible constraint of tracks and turnouts as a premise. We further construct a 01 integer programming model for arrival and departure track utilization with stability increase of station operational plan, shortest walk distance in a station and maximal station hall layout as optimization goals. Based on its characteristics, we solve it with Lingo programming.We eventually demonstrate its effectiveness with a highspeed railway station as an instance. Results show that it can accurately indicate practical issues, so it is suitable for track allocation issue of large highspeed railway station.

Key words: walking distance, high-speed railway station, track utilization, 0-1 integer programming, stability
