- Abstract
In recent years, studies on network vulnerability have grown rapidly in the fields of transportation and complex networks. Even though these two fields seem to be closely related, the overall structure is still unclear. In this study, in order to add clarity comprehensively and objectively, a citation network consisting of the vulnerability studies in the two fields is analyzed. Publication records are collected from the Web of Science and a citation network with 1,181 nodes and 4,601 links is constructed. Then the giant weakly connected component with 705 nodes and 4,584 links is extracted and analyzed. By performing a community detection algorithm, seven communities representing different research domains are identified. Then the major research development in each research domain is revealed by main path analysis. Finally we quantitatively reveal the asymmetric citation patterns between transportation and complex networks, which implies that mutual understanding between two fields is currently lacking. Since these two fields deal with vulnerability of networked systems in common, more active interdisciplinary studies should have a great potential to advance both fields.
