Abstract:In the design of road reconstruction and expansion projects, the complex traffic nodes are the core contents. Taking the node of Jujin Road in the North Yanggao Road Reconstruction Project as an example, the limiting factors of the surrounding aviation oil pipeline, high-voltage line, and the current Wuzhou Avenue Interchange that affect the engineering scheme are analyzed. Combined with the current conditions, the in-depth comparison and selection of the node scheme for Jujin Road are carried out. The road flow and traffic improvement effects under different schemes are analyzed. And the scientific and reasonable technical schemes are compared and proposed for the current traffic environment.
