Structural Hierarchy Analysis of Streets Based on Complex Network Theory

A complex network analysis method is proposed to estimate the hierarchies of urban road networks.The method is based on dual graph generated by the strokes of urban networks.Structural hierarchies of strokes are analyzed and different importance values of roads are calculated via each structural parameter evaluation.Finally,a multiple-criteria indices modeling algorithm is implemented to maintain the information of each structural index.Experimental results show the validities of this method.Structural hierarchy of strokes can reflect the structure characteristics of urban road networks.Compared with the single criterion and traditional road classification,the hierarchical levels division via multi-criteria integration is better fit the principle of perceptual grouping.
