The Chenjiaping interchange is located at the intersection point of Shiyang main road and Cheng-Yu freeway. This project is intended to improve the traffic by reconstructing the existing combination of a straight underpass and rotary into a fully directional interchange. Through the prediction and analysis of traffic volume by network science,the final version of this project creates a brand-new style of city large-scale interchange,by implementing the central government policy of constructing an environment friendly and resource conservational society,according to local terrain. This interchange maintains strong function together with compact ed arrangement,practicing the principle of humanism in accordance with the circumstance,as well as recent and future planning. The design of this interchange employs new ideas,new technologies and new materials. The existing structures are utilized after reinforcement to win economy. And the construction order is scientifically arranged,the water supply and drainage pipes,the electrical and communication cables are reasonably relocated,so that the disturbance of construction to transportation is minimized. This interchange has displayed good effects in operation.
