This study proposes a new method to determine node importance, which considers betweenness, the average shortest paths and the largest network connected sub-graph. This method not only attaches great importance to the nodes control ability in the network, but also emphasizes the interdependencies between each node more. Then, the comparison analysis is conducted to highlight the superiority of the proposed method. Finally, taking the subway network of Beijing as an example, its core site is discussed by simulation. The simulation results are consistent with the actual situation, and they demonstrate that the core site has a great potential in the whole railway network functions. In addition, the proposed normalization method has great progress over the predecessors’ research and widens the vision for later research.
