A Comparative Study on Calculation Methods of Capacity of High-speed Railway Network

Abstract

The calculation of the capacity of high-speed railway network is a basis for the evaluation of it, which has not formed a complete set of calculation system. According to the relevant research, this paper summarizes three kinds of general methods for calculating the capacity of high-speed railway network based on different conditions, including traffic distribution model based on K-shortest path, bi-level programming model and train working diagram compression method. By listing these typical models and their algorithms, this paper also summarizes the characteristics of each method, and makes a comparative analysis and screening of them. Then this paper makes a case study, applies each method to actual railway network and analyzes the results, which provides the actual basis for the comparative study of this paper.
