【Abstract】：In order to solve the problem of local congestion at roundabouts in large and medium-sized cities， this article takes the intersection of Guangming Road and Xichang Road in Zaozhuang City， Shandong Province as an example to explore ways to improve roundabouts. Through the current traffic investigation， it was found that there are problems at the intersection. Based on the current situation of the road， the overall planning and positioning， as well as the analysis and prediction conclusions of traffic flow，the paper gives the improvement scheme considering the project investment， periodand construction difficulty.
