Research Framework for Optimizing the Lighting Environment of Highway Tunnels
In order to ensure the safety of highway tunnel driving,typical problems of tunnel lighting environment were summarized.The application and research status of lighting fixtures and sight guid-ance at home and abroad were sorted out from the perspectives of setting basis,layout method,and e-conomic applicability.It is summarized that the sight guidance has the characteristic of low-cost im-provement of traffic safety,and the development trend of sight guidance methods was analyzed.Based on introducing the concept and working principle of linear induction,a research framework was pro-posed for optimizing the lighting environment of highway tunnels based on linear induction.It can im-prove the low illumination environment,chaotic setting of guidance facilities,and poor emergency guidance effect of highway tunnels,enhance the sense of distance,speed,and direction during tunnel driving,and meet the needs of drivers for passage and emergency evacuation.
