As the network gradually penetrates into all aspects of life, the transportation system as the most network-specific field, its security management issues need to be innovative from the traditional aspects. Therefore, this paper attempts to analyze the traffic network from the perspective of vulnerability. First, starting from the conceptual framework of vulnerability, the process of the concept of vulnerability is gradually complicated. At the same time, the main points of vulnerability analysis at each level are defined. Secondly, the analysis model is constructed on two aspects of network vulnerability: station and community. The concept of station vulnerability, which is similar to the traditional vulnerability analysis, is proposed in this paper. Considering the interrelationship between the indicators, the ANP method is used to construct the evaluation model. However, in the community area, the concept of regional vulnerability is proposed, which is based on the community structure of complex networks. Finally, the actual vulnerability analysis was carried out with the Beijing Subway as an example. The result of the calculation not only can obtain important stations that need to be controlled but also divide the lines in the network structure into suitable communities. This improves the collaboration between the subway system and other functional entities in society.
