Indeed, human beings’ behaviors in emergency conditions are usually quite complicated to be predicted by mathematical models. The improper layout of the building structure and the psychological and physical responses of human beings may make the evacuation delayed. Recent relevant studies have demonstrated that the high number of fire emergency casualties and injuries depends on the failure of timely evacuation of the occupants from the burning building (Fahy and Proulx 2001 Gershon et al. It provides proper solutions for human safety in facing hazard events, such as earthquakes, floods, fire, etc. It can be used to help decision-makers to determine emergency plans and to help firefighters as a training tool to simulate emergency evacuation actions.īuilding emergency management can be defined as an integrated scientific methodology that concerns several aspects, such as emergency preplanning and psychological human behavior (Gao et al. The results show that the proposed virtual reality-based system can be employed for reproducing fire emergency scenarios. To demonstrate the applicability of the proposed methodology, the emergency fire evacuation process for an existing school building is presented.
A specific software was also used to simulate in real time the crowd dynamic in the virtual environment during the emergency evacuation process. It is computed in real time based on the building information model and a fluid dynamic software. This paper shows how to integrate a virtual reality platform with numerical simulation tools to reproduce an evolutionary fire emergency scenario. In the last few years, modern technologies such as numerical simulations, virtual and augmented reality, and agent-based models represented effective tools to study phenomena, which may not be experimentally reproduced due to costs, inherent hazards, or other constraints (e.g., fire or earthquake emergencies and evacuation from buildings).
