Point-Line Optimization Study On Operation Organization Of Urban Rail Transit

With the development of national economy and the acceleration of Urbanization, urban traffic contradiction turns sharper and sharper. As its technique predominance such as great capaciy, rapid speed, good security and punctuality, urban rail transit settles the more and more contradiction of traffic supply and requirer in the big ciy. The operation management and Traffic Organization of the urban rail transit have direct influence to the transport potential, our objective of the operation management study is that urban rail transit brings the high quality service to passenger through the efficient,low cost operation organization work.The paper introducts operation organization elements and operation subsystem. The research estibalishs the optimization model of train organization, based on the introduction and analyzing passenger flow of a typical line.The optimization makes passengers and operating enterprises feeling satisfied.With the continuous development of urban rail transit, passenger flow in the transfer station has increased. Meanwhile transfer passenger accounts for a large proportion in itself. Facility capacity is the key factor for passenger flow going through smoothly.This paper summarizes the characteristics of different forms of transfer station and their applicative conditions. At the same time, it analyses passengers'behavior and psychology going through the facilities. The paper uses STEPS to simulate transfer station, and observes six indicators by analyzing the simulating model. The research gives some optimization recommendations,based on the six indicators.
