Evacuation of building fire personnel based on BIM+GIS: A review

As the consequences of building fire evacuation continue to be severe, some experts and scholars have proposed to combine building information modeling (BIM) technology with geographic information system (GIS) technology to construct a three-dimensional space scene of building fire evacuation. BIM has the advantages of refined three-dimensional modeling, and with the help of evacuation software, people evacuation and its characteristics are simulated, GIS has powerful spatial analysis functions to analyze the path. In this kind of evacuation simulation method, the two technologies complement each other to achieve quantitative analysis of qualitative indicators and efficient visualization of evacuation emergency management. This paper summarizes and analyzes the research on personnel evacuation in recent years by summarizing the current research situation in China, and puts forward the existing problems, hoping to provide ideas for the further research.
