Abstract
Due to the rapid development of complex network research, the controllability research of different kinds of large-scale actual network has become a research hotspot nowadays. The purpose of this study is to reveal the controllability of urban rail transit network. First, it built the urban rail transit network topology by analyzing the characteristics of urban rail transit network structure. Then, a controllability model of subway is set up based on control theory of state equation. In the model, we defined the departure train as driver node. Whether the system is controllable is determined by driver nodes. At last, we analyzed urban rail transit network structure and compared the controllability of the city of Beijing, Guangzhou, and Dongjing. The result shows that the existing subway network is uncontrollable because of the complex structure of subway. We can increase the number of driver nodes in order to make it controllable.
