摘要
In order to simulate evacuation from a room with multiple exits, a two-dimensional basic cellular automata (CA) model is proposed based on human behavior. In this model, two factors are taken into account, viz. spatial distance and occupant density. To make the simulation more reasonable, human behavior including inertial effect, group effect and unadventurous effect are considered in an extended model. Numerical results show that the proposed CA model is realistic and robust. A parametric study reveals the potential application of CA model in the assessment of fire safety. (C) 2007 Elsevier B.V.
