Structural Characteristics Comparisons between the Provincial Expressway Network and the Trunk Highway Network in China

Using the Network Theory, comparisons were made with node degree distributions, betweennesses, shortest path lengths, and clustering coefficients of the provincial Expressway network and Trunk Highway network consisting partly of the Expressway System and the National Highway System in the same province. Based on structural characteristics of networks, this paper focused on comparing vulnerabilities between the provincial Expressway and Trunk Highway network. In addition, destructive experiments focusing on edge betweenness were conducted, while reactions and reliabilities from the Expressway Network and Trunk Highway Network were observed. Results showed that when 15% of all segments were damaged or blocked, the general efficiency of the Expressway System reduced to half of normal, which meant the whole system almost stopped running. On the other hand, this situation would occur when 25% of segments were damaged or blocked in the Trunk Highway Network, and this indicated the Trunk Highway Network had higher reliability than the Expressway System.
