Optimization Study On Operation Orgaization Of Urban Rail Transit

In recent years, as the quickly development of city and the huge pressure of pollution, it demands to develop the speedy public traffic first, especially urban rail transit. It has become an efficient approach for the whole world to solve the urban traffic problems. The development of urban rail transit system changes with each passing day. Along with continuously extension scale of city, the urban rail transit plays more and more important role of city life. So it is facing daunting challenges. How to operate urban rail transit system efficiently is a common concerned topic. Based on theory and practice of operating, Several issues of transportation organization of urban rail line has been proposed by the system theory, according to the character of the passenger flow in urban rail lines.The research of this paper is just based on the system program operation pattern, search the space-time distribution rule of passenger flow, and establish the operation plan. In this paper, focused on the characteristics of rail transport operation, the Rail Transit Organization is optimized on the basis of the passenger flow, the following sections are included in this work:(1) The general situation of rail transit and the conception of operation organization is introduced, the research orientation of this paper is fixed, based on the analysis of research status quo on domestic and overseas.(2) The distribution over time and space of urban rail transit flow is depicted, and the passenger flow prediction method is analyzed, new achievement of traffic flow, both here and abroad, is introduced. The rationality of the urban rail transit organization is directly influenced by the prediction of traffic flow forecasts.(3) The ways and means of transport organization are summarized, including train running plan,train classifications,train routing plan,stop schedule plan and so on, introduced transport organization of them, and the foundations are laid on how to optimize transport organization.(4) According to the temporal and spatial distribution characteristic of traffic flow. Transportation operation optimization of train classification and train operating interval are put forward. Taking a nested routing mode as an example, this paper also researches the train routing mode, make an analysis on the operation form and condition of Express/Slow train program and skip running program.
