Exploration and Practice of Site-restricted Interchange Design in Central Urban Area
As an important part of urban transportation construction,urban interchange can not only improve the traffic capacity of urban roads,but also optimize the urban environment and landscape.However,the design of urban interchange faces many constraints,such as urban planning,land use,pipe network,buildings along the line and rail transit,etc.,which bring great challenges to the scheme layout of urban interchange.Taking the Baofeng Road Interchange of Hanjiang Avenue in Wuhan as an example in the paper,the main constraints and influencing factors encountered in the design of the interchange are analyzed,the traffic organization form of the ground floor is determined based on traffic demand,and finally the interchange scheme is confirmed from the aspects of the impact on People's Square and civil air defense projects,bridge construction difficulty,and project cost,which can provide reference for the design of urban interchange under similar conditions.
