In order to increase the rationality and efficiency of critical points identification of road network, and improve safety monitoring level of the road network, the hierarchy division method of the road network was studied. Based on the analysis of influence factors of road hierarchical level, this paper presented four evaluation indexes: road safety, functional, traffic flow characteristics and road infrastructure features. Roads were evaluated and sorted using the utility function. The paper achieved a hierarchical division of road network using the sample clustering analysis method, showed the basic process of the hierarchical division method through an example, and provided the basis for the identification of the critical points of the road network in future.
