Abstract: This paper analyzes the traffic characteristics of interchanges ramp, Junction and junction section, and puts forward the change of capacity of interchange ramp, Junction and junction section when the main line of interchanges congestion(service level is F). Draw lessons from & lt; The "HCM" capacity research model conducts a capacity analysis of the interchange ramp, and according to the given demand capacity, the ratio is calculated to see whether the ratio is within acceptable range
