Research On Operation Organization Of Urban Rail Transit Of Express/Local Train

In recent years,with the expansion of urban area and passenger travel demand,urban rail transit has also been improved.And in the long-distance urban rail transit line station on the station parking mode can not meet the needs of passengers fast direct,fast car combination of running program came into being.The combination of speed and vehicle combination can meet the characteristics of uneven distribution of passenger space and time and long passenger travel distance,which can effectively improve the service level and operation efficiency of urban rail transit.Based on the experience of successful operation both at home and abroad,this paper studies the combination operation plan of the fast and low car,reduces the operating cost and the passenger travel time as the starting point to establish the model of the quick stop and stop.The main contents of the paper are as follows:1.On the basis of summarizing the passenger flow and line conditions of the fast and slow car,the necessity and influence of the driving speed are analyzed,and the problems that affect the speed of the car are listed systematically.factor.2.The paper analyzes the operation cost of the enterprise and the composition of the passenger travel time,taking into account the passenger's travel choice behavior,taking the enterprise operation benefit and the passenger's time benefit as the objective function,and designing the genetic algorithm to solve.3.This paper studies the four main problems of the way of running,the form of reentry,the line of the express train and the entry and exit line,laying the foundation for the plan of the shop and put forward the method of calculating the time period of the running chart.4.Taking the rail transit line 5 of Chongqing as an example,combined with the distribution of passenger travel OD,use the established stop program model to calculate the early stop plan,so as to draw out the train running chart.
