Behaviour based motion simulation for fire evacuation procedures

Virtual reality simulation of crowd movements in urban space and in architecture is a powerful complementary verification tool to assist urban planning, architectural design, and safety assessment. This paper describes a behaviour based simulation system for modeling movements of a high-density human crowd in buildings under constrains of fire evacuation procedures. Based on a behaviour simulation model, a realistic simulation prototype of human reactions to a fire event including both normal behaviours regarding to the fire regulations and behaviours against the rules such as panic, delay to evacuate, was implemented within a high quality visualization and real-time interactive 3D virtual environment
