Abstract:Aiming at the present situation of too long transshipping of urban traffic and high-speed railway hub, taking the high-speed railway hub of West Changsha Railway Station as an example, the efficient in-and-out-station rapid collecting-distributing system is studied and proposed to coordinate the external traffic of the whole city. First, the external and internal rapid collecting-distributing system of large traffic hub area is further studied. The rapid collecting and distributing road traffic system serving the passengers in and out of the high-speed railway hub is studied. The "double-well" mode is proposed to suit the large traffic hub with the large passenger flow volume and the dispersive passenger flow directions. The in-and-out station mode of cars and taxis arriving at the high-speed railway hub is analyzed and discussed. Then, the layout of various traffic facilities around the station square is studied to ensure the efficient and accessible traffic in the service scope of the hub. Finally, the necessity of underground loop traffic serving the business districts around the high-speed railway is discussed further. And the applicable situation and the one-way anticlockwise traffic organization mode of underground loop are put forward. Through the basement contacting channel to connect the surrounding plots and using the mode of three-dimensional transportation organization, spatially, the in-and-out-station traffic of high-speed railway is separated from the traffic of surrounding business districts, which can reduce the traffic interweaving and improve the traffic efficiency of high-speed railway hub area.
