In this paper, the information dimension, volume dimension and degree volume dimension of single nodes in complex networks are calculated, and a road selection method base on fractal dimension of topological structure of road network is proposed. The diversity and difference characteristics of road network connectivity are considered in this approach. The results show that the proposed method can better maintaining the global structure of the road network, the critical local structure, and keeping the road network well topological connected compared with the four single-index road selection models based on the length, closeness centrality, betweenness centrality, degree centrality. In addition, the road selected by this approach is consistent with the roads selected by cartographers.
