Abstract:

To improve the efficiency and stability of our traffic system operation, this paper applied the complex network theory, selected railway and airline data (as of July 2015) of the prefecturelevel cities in China (not including Hong Kong, Macao and Taiwan) as the research object, and constructed the Chinese railway and airline multilayer networks. The topological characteristics and robustness of Chinese railway and airline multilayer networks were studied, and two indexes, such as average path length and network efficiency, were chosen as robustness evaluation indexes. The results include the following points: the railway and airline multilayer and its singlelayer networks all have smallworld and scalefree characteristics; the robustness of Chinese railway and airline multilayer networks is better under the random attack than under the calculated attack; the robustness of railway and airline multilayer networks is better than its two subnetworks, whether under the calculated attack or under the random attack.

Key words: railway and airline multilayer networks, robustness, the calculated attack, complex network, the random attack
