Reliability Analysis of Land Transportation Network of Guanzhong Plain Urban Agglomeration Based on Complex Network

The land transportation network of Guanzhong plain urban agglomeration has characteristics of complex network. In order to improve its operation stability, the paper introduces the complex network theory to study the land transportation network model and its reliability of Guanzhong plain urban agglomeration. In the framework of complex network theory, the construction of various types of highways and railways in Guanzhong plain urban agglomeration was analyzed. Based on the analysis of the relationship between the subnetworks and the composited complex networks, the complex network model and its topological characteristics of land transportation in Guanzhong plain urban agglomeration were constructed, and the reliability of the two subnetworks and the composited complex network was analyzed by changes of the average path length and clustering coefficient under intentional and random attacks. The results show that both the two subnetworks and multi-subnet complex networks have good connectivity reliability. intentional attack is more likely to destroy network reliability than random attack. In the random attack mode and the intentional attack mode, the multi-subnet network is more reliable than the subnetwork.
