Abstract:To study the evacuation behavior of people in a closed-environment fire situation and improve the evacuation efficiency of people in a gymnasium,this article takes the fire evacuation of a gymnasium in Xi'an as an example.Based on the cellular automaton model,people are classified according to their familiarity with the environment,and random movement,following movement,and wall-guided movement are introduced.MATLAB is used for simulation to study the impact of factors such as environmental familiarity,the proportion of people unfamiliar with the environment,and the scene on the evacuation time of people.The results show that when the proportion of people unfamiliar with the environment is small,people tend to move towards the exit and easily gather near the exit;when the proportion of people unfamiliar with the environment is large,they tend to move towards the side walls,resulting in a decrease in the utilization rate of the exit;when the number of people is fixed,the evacuation time is relatively less when the proportion of people unfamiliar with the environment is about 60%;compared with the horizontal placement of facilities at the exit,it is easy for people to gather during evacuation,leading to blind following by people unfamiliar with the environment.When facilities are placed vertically,the average evacuation time is reduced by 9.3%,which is more condu-cive to emergency evacuation of people.
