A Novel Three-Dimensional Cellular Automaton Evacuation Model

In order to effectively reduce evacuation time of pedestrians in emergencies, a novel evacuation model is proposed based on the three-dimensional cellular automation. The model, according to Moore cellular structure, firstly defmes location income and estimates evacuation time parameter, and then gives calculation formula for moving probability of pedestrians at next moment. Meanwhile, in combination with the degree of fear and moving speed, evacuation strategies and cellular evolution rules suited to the three-dimensional condition are raised. At last, by establishing simulation model, the article profoundly analyses key factors that affect evacuation time of pedestrians, and finds that the evacuation time shows a negative correlation with the exit width, but a positive correlation with pedestrian density. Appropriate increase of pedestrians' fear degree is good for reducing the whole evacuation time.
