Due to the growth and changes in traffic volume,the section from the exit ramp of urban expressways to level intersections often becomes a bottleneck on urban roads.In response to such problem,this article analyzes the reasons for congestion and proposes some meth-ods for managing congestion.And based on the theory of transportation engineering,the method of capacity analysis is adopted to verify the rationality of the expressway exit ramp connection section and downstream intersection renovation plan.The main problem solved by the con-gestion control of the exit ramp connection section of the expressway is to make the downstream intersection's traffic capacity greater than the upstream section's traffic capacity,and the length of the weaving section and queue in the connection section meet the usage needs.
