Study On Capacity Matching And Transferoptimization Of Multi System Regional Rail Transit

China’s rail transit industry is in the stage of vigorous development,with trunk railway,intercity railway,urban rail transit and other systems of rail transit.In recent years,the passenger flow of rail transit in China is increasing day by day,and the passenger demand is also increasing.At present,it is urgent to solve two problems,one is the problem of urban traffic congestion,the other is how to provide more convenient and efficient transport services for passengers.Therefore,it is necessary to promote the construction of multi system regional rail transit system with coordinated development of city railway,intercity railway,trunk railway,urban rail transit,etc.from the perspective of regional rail transit as a whole.Firstly,this paper compares the characteristics of various modes of rail transit,based on the service demand of multi-mode rail transit collaborative transportation,introduces the basic theory of multi-mode rail transit collaborative transportation from two aspects of multi-mode rail transit management system and technical system.Secondly,on the basis of this theory,this paper studies the two aspects of comprehensive transportation capacity matching and collaborative transportation transfer optimization.Aiming at the problem of comprehensive transportation capacity matching,this paper analyzes the comprehensive transportation capacity of multi-mode regional rail transit from three aspects of line network structure,line network capacity and service capacity,taking hub transportation capacity,line transportation capacity and multi-mode infrastructure capacity as its quantitative index,and finally calculates the comprehensive transportation capacity matching degree of multi-mode regional rail transit.In view of the hub transfer optimization problem,firstly,the transfer node of multi system regional rail transit collaborative transportation is analyzed,the total waiting time of passengers in the transfer process is optimized,and the departure time of urban rail transit is adjusted in combination with the train transportation plan of high-speed railway.The optimization model is established with the minimum waiting time of passengers as the objective function.Finally,taking Chengdu East Railway Station as an example,the comprehensive capacity matching evaluation and hub transfer optimization are carried out.The practical results show that the model can provide a good reference value for the planning,construction and planning of multi system regional rail transit collaborative transportation.
