Aiming at the complex urban level crossing where five roads intersect, this paper takes the Zhuji Road-Jishan Xinlu Street intersection in Guangzhou City as an example. Based on the collection of the current operating conditions, the existing problems are analyzed, and then the intersection organization plan is carried out. Optimization, and finally demonstrate the optimized scheme through effect evaluation. The research results and research process can provide a reference for the optimization analysis of road traffic organization at similar complex urban intersections.
