Abstract

Simulation of pedestrian evacuation flow from a room with asymmetrical exit layout is presented based on cellular automata (CA) in this paper. Pedestrian moving rules were established, according to two-dimensional cellular automaton Moore neighborhood. The dynamic parameters: Direction-parameter, Empty-parameter and Cognition-parameter are formulated to simplify tactically the decision-making process of pedestrians, considering the effects of pedestrian jam around exits and the width of exits on evacuation path selection in order to reduce evacuation imbalance caused by the asymmetry of exits layout, which can reflect the pedestrian judgment on the surrounding conditions and decide the pedestrian’s choice of action. The simulation results of the improved and previous models are compared and analyzed. Simulation results show that evacuation time T increases nonlinearly (exponential distribution) when system size is increased, there is a linear relationship between evacuation time and pedestrian density, however, there is a negative exponential relationship between evacuation time and exit width. At last, the best exit layout is given in this paper. The simulation results correspond with the actual, it is instructional significant for pedestrian evacuation.
