Study On Introducing New Lines To Chongqing Railway Hub And Railway Passenger Transport Distribution

Chongqing railway hub is located at the intersection of the three channels,the channel from baotou to haikou,the beijing-kunming channel and the yuchangxia channel which are planned in the national eight vertical and eight horizontal railway networks.The construction of chongqing railway hub is conducive to the formation of a railway corridor connecting the north and the south and the east and west.In the national railway medium and long term,the13 th five-year plan and the general plan of the hub,chongqing has been positioned as a large railway hub in China.With the development of national economy and the further highlighting of chongqing hub location advantage,the problems of insufficient capacity of passenger transport system of chongqing railway hub,insufficient coordination between layout and overall urban planning,and inability to reflect the location advantage of chongqing station need to be solved urgently.In this paper,combining with general layout planning of chongqing railway hub,based on the forecasting results of passenger transport demand and passenger flow characteristics of chongqing railway hub,the project of introducing Chongqing-Kunming high-speed railway,Chongqing-Xian high-speed railway,Chengdu-Chongqing Central Line and Lanzhou-Chongqing high-speed railway into chongqing hub is designed from the perspective of smooth operation organization and point-line capacity matching,and the schemes are compared comprehensively through qualitative and quantitative analysis.Through overall consideration of the line introduction scheme and the division of labor distribution of passenger stations in chongqing railway hub,the main communication directions in the hub are smooth,the transportation organization is flexible,and the point-line capacity is matched,so as to maximize the driving effect of the railway hub on economic development.On the basis of the introduction scheme of the main lines,the recommendation scheme of passenger transport layout of chongqing railway hub is finally determined.
