Simulation and Analysis of glare effect of two lane tunnel lighting under symmetrical lighting arrangement

Abstract

Glare seriously affects the quality of tunnel lighting, and also has a negative impact on drivers’ visual recognition in the tunnel. By introducing the calculation method of glare influence level G and relative threshold increment TI, the article uses DIAlux evo lighting simulation analysis software to simulate and analyze the tunnel lighting glare of different installation spacing and angle combinations under the condition of Symmetrical lighting on both sides in the tunnel. The influence range of glare produced by different installation spacing and angle combinations under symmetrical lighting is obtained. The research results show that: in the symmetrical lighting mode on both sides of the tunnel, when the angle between the driver’s sight line and the incident direction of the tunnel lighting is less than 82.38°, the lamps will produce glare to the driver. When the glare influence level of symmetrical bat-wing tunnel lamp is between 1 and 3 at any installation distance and angle under the symmetrical arrangement of lights on both sides, it is a serious glare effect.
