Abstract:

        This paper employs the method of dual topology to convert a road segment into a node and an intersection into an edge of a network (topology structure conversion of a real road network) for the importance analysis of the roads in urban road networks.We further employ such parameters as node degrees of complex networks, edge betweenness and network reliability to assess the structure characteristics of an urban road system. We eventually put this evaluation method into practice for the connection reliability analysis of Jinan urban road system under these conditions of deliberate attack and random failure.

Key words: complex network, urban road networks, reliability, dual topology, edge betweenness
