AN ACCIDENT PREVENTION AND EMERGENCY RESCUE SYSTEM FOR EXPRESSWAY TUNNELS

Using the idea of safety management for the technical transmission of modern traffic and network information as the basis, this paper sets up a traffic accident prevention and emergency rescue system for expressway tunnels, which is an important means of improving the safe operation and management of expressway tunnels. According to the characteristics of traffic accidents in expressway tunnels, the traffic accident prevention and emergency rescue system administration, consisting of a supervision layer, an infrastructure layer, a shared layer and a value-added service layer, is an integrated, comprehensive, systematic platform which incorporates data communication, database and GIS into an organic whole and has a certain intelligence function. This paper then studies the framework of an accident prevention and emergency rescue system for expressway tunnels and describes the primary function modules and workflow. Finally, the paper examines the Shaoguan tunnel of the Jing-zhu expressway in China and puts forward some constructive suggestions for setting up an accident prevention and emergency rescue system.
