crowds of people are often found in enclosed or constricted *** in such situations is usually conducted calmly,but real or perceived danger may trigger *** panicked crowds,the interpersonal distance crowd members normally observe is often overwhelmed by the physical pressure of crowd members pushing against each *** pressure can both slow evacuation and lead to injury or *** have been developed to study crowd evacuation in a range of *** paper describes the implementation,testing,and validation of a crowd evacuation model using Unity,a commercial computer game engine.A realistic physics-based model of crowd movement that calculates and considers the physical pressure crowd members exert on each other was implemented in *** implemented model was tested under both nonpanicked and panicked scenarios;those tests exhibited known qualitative characteristics of such *** model was then quantitatively validated by comparing its results to the outcome of an actual evacuation event,the 2003 fire at The Station nightclub in Rhode *** implementation and validation show that Unity can be an effective tool for evacuation modeling.
