The risk of crowd gathering in open public places is prominent,and conventional evacuation measures cannot effec-tively alleviate the risk situation of crowd gathering inside and out-side the place.It is of great significance to master the characteris-tics of evacuation behavior of people in emergencies.Shenzhen Dongmen Pedestrian Street was selected as the research area to carry out a questionnaire survey on evacuation behavior,and three evacuation behavior tendency scenarios were developed ac-cording to the crowd gathering state,namely,obedience of per-sonnel,gathering congestion response and emergency evacuation response.SPSS 25.0 Chi-square test was used to analyze the cor-relation between basic characteristics such as gender,age,group and evacuation behavior tendency.The results show that:(1)there are old and young groups,carrying packages and low envi-ronmental familiarity in pedestrian street,which affect evacuation efficiency.(2)a small number of people may continue to stay and take photos,wait for a long time,watch after encountering gath-ering congestion,or watch or even return after being evacuated to a safe area,which may lead to the internal gathering of the site can not be effectively alleviated,and form a new risk point of crowd gathering in the periphery.(3)the three groups of"male,large group and short-term tourists"have poor evacuation behav-ior,and the proportion of gathering,staying and returning is higher,especially the large group with 4 or more people are more likely to take the harmful behavior of crowding forward.
