Highways are important channels for the external development of mountainous areas.As key nodes of mountainous highways,the selection of interchange locations and the determination of interchange types are key and difficult points that need to be paid attention to in the design process of mountainous highways.The article took the Taoxi Interchange of Yiwu-Longquan section(Jinhua section)of the Yilongqing highway in mountainous areas of central and southern Zhejiang Province as an example.Taking into account factors such as turning traffic volume,linear index,terrain and land features,project scale,space utilization,investment cost,and construction difficul-ty,a comprehensive comparison of conventional and heterotypic interchange schemes was conducted at the same depth.Through qualitative and quantitative analysis,a heterotypic variant horn shaped interchange scheme that is more suitable for mountainous terrain is ultimately recommended,providing ideas for designing interchanges on mountainous highways according to local conditions and supporting diversified interchange selection.
