Study on Interchange Transformation Scheme in Urban Dense Area

Xinzhuang Interchange is located in Xuanwu District in the central city of Nanjing,which is one of the landmark areas of Nanjing's modern and international humanistic green city.Xinzhuang Interchange is also an important part of the centralized transportation system of Nanjing main hub,which is seriously congested during peak hours.On the basis of theoretical analysis,control factors such as road network planning,traffic volume distribution prediction results and current construction conditions,this paper reasonably determines the appropriate Xinzhuang interchange transformation scheme in terms of service level and capacity,project cost and traffic organization during construction period.The design idea and research method are helpful to guide the design of interworking and reconstruction scheme of dense urban areas of the same type.
