Research on Abnormal Event Classification of Expressway Tunnel based on Security Control

Abstract

Based on the perspective of tunnel traffic safety operation and control and the human, vehicle, road, and environment system in tunnel operation process, adopting event tree analysis method according to the different influencing factors, generation mechanism and performance characteristics of tunnel abnormal events, this research propose abnormal event classification tree diagram. According to the current abnormal event management and control mechanism in China, the administration departments and disposal facilities associated with different types of abnormal events in expressway tunnel operation are sorted out, which can provide decision-making support for the rapid treatment of abnormal events and realize intelligent control of tunnel.

Study on the spatial distribution of potential fire sources in highway tunnels

“…The traffic operation system is composed of multiple factors such as people, vehicles, roads and the environment. Any factor and link in the operation system are uncoordinated, which may produce a fire source and threaten the tunnel operation and driving safety [15]. Potential fire sources in tunnels refer to the energy source that can cause combustion or explosion of combustibles.…”
