In this paper, based on Smart Card Data (SCD), bus stations data and bus lines data, we present an interactive system to visually analyze the urban passenger flow. These knowledge derived from our system can help users perceive the possible traffic congestion. It is different from the previous studies which focus on detecting congestion based on car speed. Our visual analysis work consists of two...
Idea Graph is a core component of Idea Discovery, which discovers idea by converting unstructured data into a scenario graph. Since the scenario graph is complex and heterogeneous, the layouts generated by general graph layout algorithms can't well support human cognition. To tackle this issue, a novel graph layout algorithm named CiFDAL is proposed, which is a hybrid of circular layout algorithm...
