Virtual Fire Evacuation Drills through a Web-Based Serious Game

Abstract

Evacuation capacity is very important in building fire. In order to improve the safety evacuation capacity of occupants, a web-based serious game for virtual fire evacuation drills is proposed. As a prototype of the serious game, a stand-alone system for virtual drill had been developed. On this basis, the system framework of the serious game is first designed for web-based training, including the database, front and back ends. Secondly, an optimization solution including fire scenes and web codes is designed for smooth rendering performance. Lastly, a solution is designed to visualize the evacuation paths of numerous trainees, which can be used to reveal the evacuation rules, and an evaluation model of evacuation performance is created considering the features of evacuation paths and fire hazards, to provide comprehensive feedback for trainees. Thus, a convenient and accessible web-based serious game was developed. More than 100 people participated in the online virtual evacuation drill of a dormitory building fire. Through the drills, the average evacuation time of the trainees decreases from 79.77 s to 54.32 s, and the safety scores of the trainees improve from 74.71 to 81.21. Therefore, the evacuation abilities of trainees gradually improve, which demonstrates the effectiveness of the drill. Consequently, virtual fire drills using a web-based serious game can play an important role in improving the evacuation ability.
