摘要：
An extended floor field model is proposed to simulate the pedestrian evacuation in a room by considering the smoke and fire effect under fire emergency. In this new model, the visibility floor field and temperature floor field are introduced, these extensions are important for evacuation simulations under fire circumstances. Through the numerical simulations, the influence of fire locations, type of burning materials, heat release rates and exit width on evacuation are analyzed. The results show these factors have great effects on evacuation, which may be useful to understand the pedestrian evacuation under fire emergency. (C) 2014 The Authors. Published by Elsevier Ltd.
