Study on the robustness of Washington Metro Network

Abstract

The Washington subway networks is taken as the research object. The space-L network topology model of the Washington subway network is constructed, and the complex network characteristics and robustness of the Washington subway network are studied by complex network theory. Firstly, by calculating different topological network statistics, the complex network characteristics of the Washington subway network are analyzed. Secondly, through the two simulations of random attack and deliberate attack on the Washington subway network, the index values of the two attack modes are counted and their changing trends are analyzed, and the robustness of the Washington subway network under attack is analyzed. The results show that the Washington subway network has strong robustness. Deliberate attacks are more destructive to the Washington subway network, while random attacks have less impact.
