Abstract: In order to design and research personnel to interchange deeper understanding, on the diamond in-terchange, trumpet interchange, clover leaf interchange and combination type interchange and applicability analysis. This paper analyzes the current research status of interchange at home and abroad, such as the minimum spacing of interchange, the layout of distributing lanes, and the exploration of New Interchange. It points out its advantages and analyzes the shortcomings in the field of interchanges and the direction to be improved. It provides a theoretical basis for the researchers and engineering designers.
