Simulation on Occupant Evacuation during Aircraft Emergency Based on Cellular Automata

The characteristics of occupant evacuation during aircraft emergency were analyzed according to emergency evacuation guidance systems, light intensity and evacuees. Evacuees included occupant's physiological characteristics and their psychological characteristics. The occupant's physiological characteristics were mainly related to panic, pressure and conformity. The psychological characteristics involved in waist circumference, age, gender and height. The above factors were applied to the aircraft emergency evacuation simulation on cellular automata. Then, the cabin environment model and the occupant model were presented. The occupant model included individual pre-reaction time submodel, cabin channel velocity submodel and escape time submodel of exit. Study shows that the results could provid an auxiliary verification information for aircraft initial certification, and could provide strategic guidance for airline to carry out personnel evacuation and emergency training for employees.
