Emergency Evacuation Simulation Of Students Groups Based On VR Technology

With the social development and increasing investment in education, that more and more children can receive schooling is deeply gratifying, but their safety at school is gradually becoming prominent. Since schools are important places to learn, live and grow for students, students must be strong support for personal safety. Some schools in the face of unexpected events, such as earthquakes, fires, violence, etc., in need of emergency evacuation, led to the evacuation of students crowding each other in time, or even fall trampling each other, resulting in heavy casualties, such as earthquake evacuation of some schools, ineffective when, Hunan, such as the stampede of students on campus.How to reduce casualties in emergency evacuation is an important research topic of related scientific research institutions and administration. A large-scale evacuation simulation is a project that needs a lot of human and material resources. And due to the dependence of human actions and psychological on many external factors, evacuation test is difficult to execute, even for testing. It is also difficult for person to access to the unexpected events, such as a state of panic, test results, to some extent, can not reflect the true situation. Therefore, using a computer to simulate evacuation behavior has become an important technology tool in the international security research.Currently, some achievements have been obtained in the research of evacuation simulation at home and abroad. After analyzing the characteristics of the existing evacuation models, this paper uses the simulation technology of group behavior based on Multi-Agent, and makes improved design of the characteristics of the students groups in the simulation, establish a simulation program of students group in evacuation. It also does some experiments, and makes some data statistics and analyses. The main studies of this paper include:analyze of students group behaviors in the emergencies, build evacuation simulation model for the main behaviors of students groups; research the methods of modeling the flexible structures of a variety of terrain environment, which can easily make the program applied to the various structures of the environment; use and improve the Multi-Agent based simulation technology of group behaviors, and come up with more suitable modeling method for the simulation target of this paper; improve the simulation algorithm of the existing models, including individual and group behaviors movement algorithm, path finding algorithm; use the research results in this evacuation process simulation of this paper to do the simulation, then get statistical data and do the analyses.
