A Method for Calculating Capacity of A Medium-Speed Maglev Line

Abstract

The purpose of the analysis of capacity usage is to utilize the medium-speed maglev infrastructure in a more efficient and practical way. In this paper, the power supply zone is modeled by 'operation resource' which ensures the different safety headway of successive trains depending on the running speed. Then, by the analysis of virtual cell, a capacity calculating model is built to solve the problem of medium-speed maglev line capacity. And a Lagrangian relaxation algorithm is designed to decrease the difficulty of solving the model by relaxing the capacity constraint. Finally, numerical examples are given to illustrate the correctness of the proposed methods.
