Interchange is an important node of the expressway network,its design scheme directly affects the operation efficiency of the road network system.According to the scheme design of the Chemingyu Interchange in Lixi Expressway,this paper analyzed the design principles and main considerations in designing the interchange.Based on technical specifications,traffic flow,and other control factors,three Chemingyu Interchange schemes were proposed,and the comparison process was introduced from aspects of interchange functions,safety,cost,and other factors.Finally,the optimum scheme was determined,providing a certain reference for the design of similar expressway interchanges.
