Modeling Urban Panic
January 15th, 2008Via: Pruned:
Paul Torrens is someone after our hearts, for he has developed a realistic computer 3D model that can predict crowd behavior in various spatial configurations.
It can simulate, for instance, how people navigate through busy city streets, shoppers through urban shopping centers, and tourists through unfamiliar landscapes.
“The goal of this project is to develop a reusable and behaviorally founded computer model of pedestrian movement and crowd behavior amid dense urban environments, to serve as a test-bed for experimentation,” says Torrens. “The idea is to use the model to test hypotheses, real-world plans and strategies that are not very easy, or are impossible to test in practice.”
Such as the following: 1) simulate how a crowd flees from a burning car toward a single evacuation point; 2) test out how a pathogen might be transmitted through a mobile pedestrian over a short period of time; 3) see how the existing urban grid facilitate or does not facilitate mass evacuation prior to a hurricane landfall or in the event of dirty bomb detonation; 4) design a mall which can compel customers to shop to the point of bankruptcy, to walk obliviously for miles and miles and miles, endlessly to the point of physical exhaustion and even death; 5) identify, if possible, the tell-tale signs of a peaceful crowd about to metamorphosize into a hellish mob; 6) determine how various urban typologies, such as plazas, parks, major arterial streets and banlieues, can be reconfigured in situ into a neutralizing force when crowds do become riotous; and 7) conversely, figure out how one could, through spatial manipulation, inflame a crowd, even a very small one, to set in motion a series of events that culminates into a full scale Revolution or just your average everyday Southeast Asian coup d’état — regime change through landscape architecture.

how do they know the model they’re simulating is or will be accurate?
