Experimental study on non-adaptive behavior crowd evacuation in auditorium

Abstract

In the event of an emergency, the crowd may exhibit behaviors that are not normally present due to panic and tension. These behaviors are collectively referred to as non-adaptive behaviors, mainly including reentry behavior, companion behavior, and herd behavior. To study the impact and degree of influence of these behaviors on crowd evacuation results, this study selected a university auditorium as the research object, and convened school volunteers to conduct on-site evacuation experiments in the auditorium. Real time observation and data analysis were conducted on the herd effect, companion behavior, and reentry behavior during the experiment, and compared with basic experiments. The focus was on indicators such as evacuation time, evacuation speed, and exit decision-making behavior. The experimental results indicate that reentry behavior, companion behavior, and herd effect are all unfavorable for crowd evacuation.
