Research on Personnel Evacuation Selection Strategy Based on Virtual Reality Technology

In recent years, many cities have carried out the planning and construction of urban underground complexes integrating commerce, entertainment and transportation. Urban underground complexes are different from traditional ground high-rise buildings, with environmental characteristics such as deep burial, large single area, and limited evacuation exits, and when a fire is carried out for emergency evacuation. Therefore, how to carry out the research on the evacuation behaviour of personnel according to the environmental characteristics of urban underground complex has become an important problem that needs to be solved urgently at this stage. In view of this situation, this paper proposes to try to use virtual reality technology to study the evacuation behaviour and evacuation effect of personnel in the complex, and put forward corresponding optimization design suggestions. The use of VR technology for evacuation simulation testing and evaluation overcomes the problems of high cost and organizational difficulty in field evaluation and optimization; on the other hand, due to the high simulation of the real environment and the introduction of human subjective factors, it can make up for the shortcomings of the current method of using computer programs to simulate subway station evacuation to a certain extent.
