Dispatching High-Speed Rail Trains via Utilizing the Reverse Direction Track: Adaptive Rescheduling Strategies and Application

Abstract

This paper studies the train rescheduling problem on high-speed railway corridor in the situation where contingencies occur and lead to sudden deceleration of some trains. First, we develop an adaptive rescheduling strategy (AR-S) which allows normal trains to use reverse direction track to overtake front decelerating trains based on delay comparison under different path choices. Second, the traditional rescheduling strategy (TR-S) which does not allow any trains to switch tracks is mentioned as a sharp contrast to AR-S. Furthermore, a performance evaluation criterion is designed to evaluate the effectiveness of the train rescheduling approaches. Finally, numerical experiments carried out on Beijing-Tianjin intercity high-speed railway show that AR-S can reduce the total delay of trains up to 24% in comparison with TR-S.

A Resilience‐Based Security Assessment Approach for CBTC Systems

“…At present, railway is developing rapidly around the world, especially in China, where the high-speed railway (HSR) has a total length of 35,000 kilometers, accounting for approximately 66.7% of the world's high-speed railways [1]. China has also made significant progress in urban rail transit; there are more than 200 lines, and the total operation length is more than 6000 km [2].…”
