Abstract:Scientifically determining the scale of various traffic connection facilities plays an important role in the design of comprehensive transportation hub. Taking Shengzhou Xinchang station as an example, this paper firstly puts forward the traffic functions and connecting principles of various connecting facilities in the front square of the high-speed railway station; Secondly, it forecasts the demand of various traffic connection modes according to the relevant design data of the high-speed railway station. Thirdly, it states the layout standard and calculation method of traffic connection facilities. Finally, after calculating the scale of various traffic facilities, it optimizes and adjusts the scale in combination with the layout form and traffic flow line to obtain the optimal scheme.
