Research on the computer system of train set shunting plan safety optimization of the hub type high-speed railway station

Abstract

Because the high-speed railway lines have connected into a network in China, the research of safety optimization of train set shunting plan of the hub type high-speed railway station is of great practical significance. To solve this problem, a time-space conflict resolution algorithm is proposed to minimize the total wait time of the train set on the station track, to optimize the timing and route of the train set shunting operation in two dimensions, and thus eliminate the route conflict. A computer system is developed based on the algorithm, a real world case study shows that the algorithm can eliminate the train route conflicts, ensure the safety of the plan, and the total wait time of the train set on the track is significantly decreased, and the utilization efficiency of the track is improved.
