摘要：

An existing cellular automaton evacuation model is modified to simulate an evacuation experiment conducted in a classroom with obstacles. In the modified model, the impact of the occupant density around exits on human behavior in evacuation is considered. The simulation and experimental results prove that this improvement makes sense, because besides the spatial distance to exits, people may also choose the exit according to the occupant density around exits, The distribution of individual evacuation times as a function of initial positions and the dynamics of the evacuation process are Studied. Comparison between the experimental and simulation results Shows that the model can reproduce the experiment well. The improvement of the CA model is useful for further Study. (C) 2009 Elsevier B.V.
