Outline
To address the issues of reduced network transport capacity and increased operational safety risks caused by large-scale passenger stranding when unidirectional service interruptions occur on urban rail transit lines, a train rescheduling model based on virtual coupling technology is constructed, and the optimization model is utilized to characterize the train rescheduling process under virtual coupling technology. A hybrid two-layer simulated annealing-genetic algorithm is employed to solve the problem. Finally, taking a case of unidirectional disruption in a city's subway line as an example, the feasibility and effectiveness of the proposed strategy are verified. The results demonstrate that compared with the traditional reverse operation strategy, the reverse operation strategy under virtual coupling technology reduces passenger total waiting time by 16.4%, passenger waiting time at stations by 14.1%, and significantly decreases the number of stranded passengers. Moreover, the flexibility and efficiency of train operation adjustments are substantially enhanced. The findings provide a modeling and optimization approach for train rescheduling under similar operational disruption scenarios.
