Crowd Evacuation Dynamics (IMAGE) Arizona State University Caption This and other images are stills from a 4-D interactive model of crowd evacuation dynamics in a dense urban setting, used to explore individual and collective behavior under emergency scenarios. Synthetic, but life-like, "agents" are programmed with individual, independent and autonomous behavior. A selection of agents are dropped into a simulated city and told to evacuate toward a single exit. They will navigate through the city setting to safety. The crowd, in conjunction with the built environment, generates its own traffic dynamics, which propagate through the system and cause dangerous congestion events. The model can be used as a synthetic laboratory to explore how crowds might form under different environmental conditions, or what patterns of independent or collaborative human behavior are influential in calming panicked groups. This image shows that as crowds collect in the streets, congestion forms. This screenshot illustrates the model running with minimal rendering and low polygon counts. The model can run in real-time under these settings.
