Topology Structure Improvement Strategy for Urban Road Networks

Abstract

To improve the average travel efficiency of the urban road networks, we propose a topology structure improvement strategy which aims connect the nodes with smallest and the second smallest degree values around the node with the biggest degree value by edges. Finally, the road networks of Deyang city is taken as an example for simulation. The results show that the topology structure improvement strategy can improve the average travel efficiency greatly with the increase of the number of the edges added to the network.
