MULTI-USER COLLABORATIVE VIRTUAL EMERGENCY DRILL SYSTEM FOR URBAN ROAD EMERGENCIES

Abstract. In order to comprehensively improve the coordination and emergency response ability of road emergency commanders and rescuers to various road emergencies, analyze the problems faced by road emergency personnel in rescue training, and propose a simulation drill method combining virtual reality visualization technology with emergency rescue training content to form an interactive drill system.This paper elaborates the key technologies, architecture system and functional design of the system in detail, introduces and implements a complete set of virtual emergency drill disposal process based on the case of landslides blocking urban roads in flood season. The Internet and virtual reality technology are applied to build road emergency scenes. The emergency drill personnel carry out remote interactive virtual collaborative emergency drills in the same virtual environment, so as to realize the repeated deduction drills of road emergencies, and design the emergency disposition of scientific assessment system for drill personnel to evaluate objectively the disposal process, It effectively improves the emergency response and rescue ability of emergency personnel, and solve the problems faced by the current road emergency practice drills, such as less times, high cost, single scene and subject, etc.
