Railway Passenger Trains Unidirectional Connection Scheme Under Line Operation Interruption
To reduce the impact of line interruptions on railway passenger transportation,this paper proposes an optimization method for the connection scheme when there is interruption of the train operations.The method is based on the complementarity between various modes of the comprehensive transportation network.The cost and passenger delay time of the connection scheme are analyzed from the changes in passenger train operation and connection scheme of comprehensive transportation transfer plan.Considering the factors of turnaround and arrival/departure capacity of transfer stations,the capacity of receiving vehicles,and the relationship between the station and vehicle stops,this paper develops a bi-objective programming model for passenger train unidirectional connection scheme optimization with the objectives of minimizing passenger travel time delay and the cost of the connection scheme.The algorithm is divided into multiple time periods based on the intensity of train arrival and departure time.The remaining turning capacity is analyzed to reduce the search space of the algorithm,and the feasible candidate set of train stations is established.A time-segmented Tabu Search algorithm is designed to solve the model.The results from the numerical example indicate that when a line interruption occurs,the connection scheme should choose a station with a closer connection distance.The average cost and total delay of transportation can be reduced by 45.3%and 21.2%compared to stop at the original arrival station.Therefore,using stations that no longer provide passenger train services for connection can reduce the impact of the line interruption.The proposed method can provide references for the decision-makings under the line interruption conditions.
