Given the important role of online check-in information from social media data (Foursquare, Twitter, etc), we aim to extract meaningful movement information on individuals and understand travel patterns in the urban area. Geo-tagged location information becomes a powerful data source to help with the related study area in the past decade. In this study, we analyze the geo-tagged Twitter trajectories and generate a movement network to summarize the human mobilities. In order to understand travel behavior of people who live in the Washington DC Metropolitan Area, we reveal the structure of the movement network through the k-core decomposition method and extract a hierarchical network structure with three layers: core, bridge and periphery layer. Through the analysis of the three network subsets, we have a better understanding of the global connections and local connections between individuals and locations. The findings in this study could be helpful to improve public transportation services in the Washington DC Metropolitan Area.
