公路隧道运营安全预警系统关键技术研究

AbstractIn recent years,China's transportation industry is undergoing earth-shakingchanges,and people's lives are getting better and better.But at the same time,weshould also see that with the steady development of traffic roads,vehicles and tunnelconstruction,our traffic travel pressure is also increasing day by day.Many safetyhazards are threatening people's lives and property at all times.The paper mainly analyzes and studies the related aspects at home and abroad,focuses on the safety hazards of road tunnels in China in recent years,and highlightsthe possible causes of safety hazards,and gives the starting point and the foothold ofthis study.Then,the paper conducts a risk analysis on the safety of road tunnel operations.A security risk early warning model was established.Finally,related technologies ofdata fusion,big data analysis and fuzzy comprehensive evaluation were discussed.recent years,Key words:Highway tunnel;risk assessment;risk warning;fuzzycomprehensive evaluation
