Emergency Evacuation Plan of the Louvre Based on Cellular Automata Superposition Model

The Louvre is a famous French building and a tourist attraction.It is of great significance to make an emergency evacuation plan for tourists.A social force model and cellular automata were established to simulate the crowd evacuation in unidimensional plane,and then the downstairs model was considered to simulate three-dimensional evacuation.Finally the real evacuation situation was simulated,considering the hazard source as well as other factors.The study found that the exit was closer to the corner,and the evacuation distance of descending stairs could be controlled between 0.3 and 0.6 m to maximize evacuation efficiency.The influence of the hazard at the edge of the channel was greater than that at the center of the channel.Therefore,in the process of evacuation,the staff should be guided to the nearest exit,to maintain the optimal distance,the staff to eliminate the danger source in the center of the passage.
