Research on Maintenance Method of Tunnel Lighting Based on Driving Safety
In order to solve the driving safety problem caused by the reduction of road surface brightness due to the change of tunnel luminescence status,this paper calculates the road surface brightness value of luminescence failure through field measurement and simulation,analyzes the influence of road surface brightness uniformity on the safety of highway tunnel luminescence,and conducts field small target visual recognition tests on different combinations of luminescence failure and failure of highway tunnel luminescence.The analytic hierarchy process and Topsis comprehensive evaluation model were used to analyze the test results.The results show that,targeted maintenance methods for lighting fixtures should be proposed for different failure combinations;when the traffic safety factor is much higher than 0.52,the light flux of the tunnel lighting can be reduced appropriately to save while ensuring the traffic safety of the tunnel.
