Study On Fire Evacuation Time With Human Behavior Being Considered

More and more factors were considered in calculating the safety evacuation time with theimprovement of the technology of fire protection and the increasing requirements of buildingfire protection. In the1970s, the empirical equations were used to calculate the evacuationtime while many kinds of evacuation simulation software are used in modern times instead.Moving distance and moving speed were considered while parameters such as density andexpected speed are concluded nowadays. From only considering personnel evacuation time toconsidering the pre-evacuation was imperative. In this paper, based on the behavioral science，by analyzing the personnel response and action sequence when human were in the time of fire,the behavior of human could be analyzed. By the way of questionnaire, the statistics ofattitudes of the reaction and the behavior of human in fire are gathered. By learning the neuralnetwork and predicting the influence of personnel characteristics to human response andbehavior in fire, the human reaction and behavior in fire prediction model was established.Simulation of evacuation time with human behavior being consided was accomplished byusing the fire simulation software and evacuation simulation software. Difference betweenevacuation time with human behavior and tradition evacuation time was proved relate toperson density.
