Abstract：
In order to reduce the impact of glare on the safety of highway tunnels, the area in a highway tunnel affected by lighting glare was studied by combining analog simulation and quantitative analysis. Using a calculation method introducing the glare constant G and relative threshold increment T1, the glare-affected areas generated by three kinds of glare arrangements, i.e., symmetrical, staggered, and centralized, were obtained by a simulative analysis of tunnel lighting glare. The results show that the glare-affected area for the symmetrical arrangement is 75.73°, 76.22° for the centralized one, and 79.58° for the staggered one. Based on the calculation analysis of glare constant G, the following conclusion was drawn: no matter which kind of luminaire arrangement is applied in tunnel lighting, once glare impact occurs, the drivers in the tunnel will be endangered.
