Evacuation Simulation Based on 2.5D Cellular Automata: To Consider Individual Character and Following Behavior

The key of personnel evacuation simulation is the model establishment. Based on analyzing the existing methods, and introducing the concept of elevation to describe 3D space with 2D plane, the paper researches and establishes crowd evacuation model based on 2.5D cellular automata. In order to make the simulation results closer to reality, it analyzes the main influence factors of personnel evacuation in case of an emergency. In consideration of the mutual influence caused by conflict during evacuation, it proposes the mutations of the crowd system structure as well as the analysis of mobile power factor. Experiment shows that, the simulation effect of 2.5D model considering the elevation factors is better than that of the 2D model, can be closer to the real situation.
