摘要：

The public transport network vulnerability of Lanzhou is studied based on complex network theory. Firstly, the bus stations network are constructed according to the space L model and the static topological properties is analyzed. Then, the metrics about the vulnerability of urban public transport network is established on the basis of the random failure and selective attack of complex networks, and the corresponding performances are presented. The results show that the vulnerability of a selective attack is far stronger than that of random failure because of the special features of the valley terrain in Lanzhou. Finally, combined with the vulnerability of public transport network, the key station selection strategy is studied. It shows that the selection strategy based on the degree is more suitable for Lanzhou. These results provide a theoretical basis to support decision making on transportation planning and urban traffic network optimization for Lanzhou. Copyright © 2016 by Science Press.
