Research on Dynamic Adjustment of Arrival and Departure Tracks in High-Speed Railway Station Based on Rolling Horizon Optimization

As one of the key points of traffic control activities, the dynamic adjustment of the arrival and departure tracks of high-speed railway station has the characteristics of complexity and strong real-time performance, so it is urgent to realize automatic and intelligent tools for arrival and departure tracks adjustment. This paper elaborates on the essence of dynamic adjustment of arrival and departure tracks, introduces the rolling horizon scheduling strategy, constructs a dynamic adjustment model of arrival and departure tracks by establishing a 0-1 integer programming model with the goal of minimizing the total delay time of trains, and adopts genetic algorithm to solve the problem. Taking a specific high-speed railway station as an example, the calculation is carried out according to the arrival and departure time and delay information of trains in the train working diagram. The results show that this model can effectively improve the real-time adjustment of arrival and departure tracks, ensure the stable operation of trains in the station, and provide research support for intelligent traffic control in high-speed railway station.
