Research On Train Operation Plan In Chengdu Regional Railway Under The Background Of Integrative Passenger Transport

In recent years,Chengdu's population spillover and traffic congestion are becoming more and more serious.In order to solve this problem,Chengdu continuously develops the regional railway to deepen the traffic connection between the central city and the satellite towns.In the background of the integration of passenger transport system in Chengdu,the passenger travel demand is also rising,while the regional railway as part of the city's comprehensive transportation,develop high quality city railway transportation organization scheme to better serve passengers has become a serious problem.And the planning of the regional train is the key content of the transportation organization.It is of great practical significance to make a scientific and rational formulation of the plan for the opening of the railway train.In view of this,the main research contents of this paper include this following:1.summarize and learn from the experience and research results of domestic and international railway development,analyze the connotation and implementation of integrated rail transit system,and put forward the development orientation of Chengdu urban railway,the development direction of organization mode and the problems to be solved.2.Through the analysis of the characteristics of the city railway,the structure of the road network and the relationship of market competition,the location of the passenger flow in Chengdu City railway is obtained.3.Studying the characteristics of passenger flow,cross line passenger flow and branch passenger flow in Chengdu urban railway line.We calculated and analyzed the imbalance of passenger flow in the line direction and section.Combined with the characteristics of passenger flow,explore the train operation plan.4.After studying the factors of cross line passenger flow,station and line passing ability and the interference of train running to road network,the opening section of cross line train is designed.With the goal of the lowest transportation costand the shortest travel time,a dual goal programming model for the train planning of Chengdu City railway is established.5.Based on the annual passenger traffic volume(OD)predicted by the Chengdu railway in the year of 2020,we use LINGO12.0 software to solve the model,and confirm the Chengdu City railway train operation plan,and put forward some suggestions.
