Urban Road Hierarchy Based on Road Arteriality

Abstract:

This study firstly defines the arteriality of roads as an indicator to describe the relative importance of road in network topology,and uses betweenness centrality to calculate the arteriality of each road.Then a new method of road hierarchy is proposed by quantitatively calculating the arteriality of each road in the network.Finally,the reasonability of this new method is verified by a comparative study of the results of conventional road hierarchy method and this new calculation method.
