Overall Design Scheme of Tongcheng Avenue Expressway in Xiaoshan
With the gradual transformation of Hangzhou's urban form into an open spatial layout structure,Xiaoshan City,as the Jiangnan City of Hangzhou's"three sub cities",the urban expressway system is one of the important measures to integrate and reconstruct the spatial relationship between Xiaoshan City and Hangzhou's central city.Tongcheng Avenue is the"one vertical"of the"three-vertical and five-horizontal"skeleton road network in Hangzhou,and also a part of the"three-vertical and two-horizontal"skeleton road network in Xiaoshan District.The overall design scheme of Tongcheng Avenue Expressway in Xiaoshan District is systematically introduced including the road function positioning and service object research,the demonstration of the overall route direction,the analysis of construction mode and scale.Finally the overall layout scheme of the whole line is put forward.Through the systematic study on the overall layout of Tongcheng Avenue Expressway,it is hoped to provide a reference for the preliminary scheme study of urban expressways in China.
