Abstract
In complex environments, urban rail transit stations are susceptible to various factors that cause station function loss. Therefore, how to evaluate and quantify the key nodes in the network and solve the fluctuation of the whole network capacity under the intentional and random attacks has become an important issue. In this paper, the method of evaluating important nodes is defined according to the complex network index, and the efficiency of the road network under different attack rules is solved. According to the experimental results, the Beijing railway network was evaluated. It was found that the urban rail network had strong resistance under single-point attack, and it was very vulnerable under coordinated attack.
