| Abstract: | At present,the interchange planning and design are always based on the changes of the terrain and objects in order to design interchange＇s form.The methods are definitely led to some flaws in the aspects of traffic function for interchange.For example,it can cause traffic jam and blockage,it can also cause idles and waste of the facilities for few traffic flows,etc.Besides,interchange is the comprehensive structure of road and bridge,the interchange＇s grade is a technological rank of interchange in application function.And it reflects the technical condition of interchange and the high and low of its indexes.Accordingly,the determination of interchange grade and types is the important contents of planning and design of interchange.based on current situation of highway interchange grade in China,the writer proposes some opinions which are discussed by the colleagues. |
