Research on Selection of Interchange Scheme for Middle Ring West Road of Jiaxing Urban Expressway
Urban interchange is a kind of traffic transfer method used to connect different grades of roads on urban expressways.It is usually composed of interchange ramps,which allows vehicles to smoothly transfer from one expressway to another.It is an important traffic design method to improve the traffic efficiency of urban expressways and reduce traffic congestion.The selection of urban expressway interchange should consider various aspects such as traffic function,interchange level,environmental impact,pipeline relocation,land acquisition and demolition,and traffic impact.Taking the selection of Middle Ring West Road Interchange in Tongxiang Avenue Expressway engineering in Jiaxing City as an example,this paper first analyzes the traffic flow of the interchange and the influencing factors of the case engineering,and then puts forward different design schemes of urban elevated expressway interchange,and compares and optimizes the initial design schemes for reference.
