Abstract

Maintaining the resilience of transportation system is crucial for the overall sustainability of a city. As a complexed system, the city road system can be modeled as networks. Studies investigating the relationship network structures and functionality provide a novel perspective to investigate the robustness of a city road network. In this study, the road network of Urumqi Municipality was modeled at three different spatial scales: road section, road name and road community, to investigate the response of road network under two attack strategies – random and initial degree based attack. The performance of road network are diversified at three spatial scales under different strategies, which help to pinpoint two major weakness of network robustness: relatively low efficiency of network connectivity at road section scale, and key roads that vulnerable to intentional degree based attack strategy at road name scale. Whereby, suggestions are propounded against this two weaknesses for solidify the resilience of the road network of Urumqi Municipality.
