Study On The Train Routing Plan Of The Guangfo Circle Line

With the rapid development of economy and high speed of urbanization, regional economic integration has gradually formed. Pearl River Delta is an economically developed area with large population. However, it is hard to meet the needs of travelers using existing transportation modes. In to relief the pressure of high passenger demand, Pearl River Delta intercity railway network is designed. Being one of the important parts of Pearl River Delta intercity railway network, it is vital to research train routing plan of GuangFo Circle Line in different stages in order to improve operation efficiency, reduce waste based on passenger flow forecast. Therefore, this paper is focused on transportation organization mode and train routing plan of GuangFo Circle Line.This paper includes several parts shown as follows:(1) The general situation and passenger flow analysis of GuangFo. Pearl River Delta intercity railway network and GuangFo are introduced and function orientation of GuangFo is presented in this paper. Then the comparison between GuangFo and urban rail transit is described. Moreover, analysis the section passenger of GuangFo circle line, discusses the inter line passenger flow and the inter line passenger flow organization mode, and then comparison the advantages and disadvantages between the two inter line passenger flow organization mode. In the end, passenger flow volume of near and forward candidate routing plan and passenger flow composition are analyzed in the paper.(2) The optimization of train routing plan. Firstly, the paper describes the model of train routing organization, which based on the analysis of cross-line railway composition and a mathematical programming model is built with the minimum cost of railway operation and the shortest passenger travel. And then solve the model based on genetic algorithm. After solving the model, according to the actual situation, put forward the principle of optimization. Finally gives the train routing scheme.(3) Determining the optimized train routing plan of GuangFo in short and long term. After obtaining the candidate train routing set, carrying capacity, transfer efficiency and passenger transfer volume are compared with each other. Considering the interests of intercity railway transportation enterprises and passengers, Based on the facts, transportation organization adaptability, engineering adaptability and the characteristic of the lines. Finally, the paper obtains the optimized train routing plan of GuangFo in short and long term.
