Study On Optimal Design Of Emergency Sign System In Subway Emergency

Shanghai is a national central city,so the expansion of urban construction scale also increases people's demand for subway travel.However,subway stations are characterized by dense crowds,large flow of people and complex space,has received attention from many parties,the existing emergency identification system can no longer meet the needs of rapid and efficient evacuation of subway passengers in the event of an emergency in a complex subway scene.Therefore,in the academic field,some scholars have studied the subway emergency sign system,but at present,the existing research is to improve and optimize the emergency sign itself to boost the evacuation efficiency,and there is a lack of attention to the actual association between the various evacuation behaviors taken by subway travelers in emergency events and the emergency sign system.Therefore,from the perspective of the subway passengers,this paper discusses the relationship between emergency signs and evacuation behavior,and then takes targeted optimization design,which can not only improve the defects of the existing emergency identification system,but also enrich the theoretical system in the field of emergency identification system.The research of the thesis starts with desktop research and field investigation,combing the environment-space and sorting out the three-dimensional space layout characteristics of Shanghai People's Square subway station.Based on the field investigation,combined with the possible emergency events in the subway station,this paper summarizes the environmental characteristics of the emergency events in Shanghai People's Square subway station,and further combs out the evacuation behaviors and influencing factors of the subway passengers in the emergency events.Then,based on the analysis of the environmental characteristics and the evacuation behavior of the traveling crowd,using the social cognitive theory model to build the evacuation behavior model of the crowd,analyzes the specific impact mechanism of the emergency sign system on the evacuation behavior,and further studies the impact factors of the effectiveness of the emergency sign system according to the conclusion.Next,by analyzing the needs of subway passengers,the paper summarizes the design objectives and needs of the emergency identification system,and studies the intelligent technology currently applied to the emergency identification system,which provides technical feasibility guidance for the final implementation of the scheme.Finally,on the basis of the model,the intelligent optimization design of the emergency identification system of Shanghai People's Square subway station wascarried out,and the final plan was evaluated.A set of emergency identification system was designed for the people traveling in the subway.The actual result of the thesis is to design an emergency identification system that is more adaptable to emergency events for the people traveling in the subway,which not only provides a certain reference significance for scholars in related fields in the follow-up in-depth research,but also can promote the development and improvement of the emergency identification system system of the subway space in China.There are 78 figures,31 tables and 113 references in this paper...
