The paper first classifies the congestion levels of intersections and links into 3 classes using a hierarchical clustering method,which can not only distinguish the importance of various intersections but can be helpful in planning their capacities.Then it formulates a state parameter,named maximum flow,which may contribute in estimating the congestion level of network as a whole.Finally,the modified cutting-set matrix algorithm,namely multiple-input-multiple-output maximum flow method,is designed and the feasibility is proved by experimental results.
