Abstract:

Through analyzing characteristics of arrival and departure of trains as well as passenger services, and considering technique requirements of train arrival & departure and passenger organization in high-speed railway hub-station, the use of arrivaldeparture track and route selection were taken as a whole to be optimized comprehensively. Aiming at the equilibrium use of arrivaldeparture track, the equilibrium workload of ticketcheck entrance, and the minimum conflict of train arriving and departing, the 01 integer programming models were established. Meanwhile, the ant colony algorithm was designed to solve practical problems. Taking Guangzhou South station for an example, results showed that the utilization of arrivaldeparture tracks and the workload of ticketcheck entrances were more balanced, and the minimum time interval of two trains which occupied the same arrivaldeparture track was more reasonable, which was beneficial to the adjustment of track and time when the train was delayed and disturbed, achieving goals of optimization for utilization of arrivaldeparture tracks and route selection.

Key words: high-speed railway, utilization of arrival-departure tracks, ant colony algorithm, hub-station, route selection
