Abstract:

In this paper, quantitative analysis of all the factors affecting train routing scheme and train formation plan was made, and the integrated planning model was established from two perspectives of passengers and operators, and related solving algorithm was put forward based on genetic algorithm. When compared with the scheme of single route and single formation, the results showed that using the optimization scheme presented in this paper by flexible formation and short routing operation could reduce 13.6% waiting time, 2.65% operating cost and 12.88% the number of serviceable car, and its feasibility was proved by sensitivity analysis.

Key words: urban rail transit, train formation plan, genetic algorithm, sensitivity analysis, train routing scheme, integration of routing and formation
