Optimizing a High-Speed Railway Operation Plan Based on Train Capacity and Service Frequency

In this paper, a model to optimize a high-speed railway operation plan by dividing it into a train route plan and train stop schedule plan was developed based on the train capacity and service frequency. To capture the intersection between the operator and the passenger, a multiobjective model was established for a high-speed railway corridor. This multiobjective model can be divided into two submodels. For the operator, the train empty seat minimization model seeks to improve the effective utilization of the seats, whereas for passengers, the goal is to minimize total travel time costs. The train and station service capacities and constraints were considered to better model the operation of trains on a high-speed railway line. Furthermore, to obtain a feasible solution to railway operation planning, a greedy heuristics algorithm is proposed, which included two stages. Based on the real data of the Beijing-Shanghai high-speed railway corridor in China, the effectiveness of the proposed model and method were verified.
