Visual Analytic Method for Metro Anomaly Detection and Diffusion

Figure 2

System interface. (a) Anomaly diffusion view: display anomalies and demonstrate the spatiotemporal law of anomalies. (b) Interaction panel: provide some interactive functionality. (c) Overview view: grasp the running status of all stations. (d) Matrix view: show the result of anomaly detection. (e) Verification view: show passenger flow changes on the day compared with historical passenger flow.
