摘要：	During the process of vehicles in and out of the tunnel, the driver's vision is affected by light and dark adaptation.Natural light intensity outside tunnels is a decisive influence on the parameters of visual adaptation and tunnel lighting design.Using DIALux simulation software, the feasts typical natural light inside and outside the tunnel entrance and the illumination conditions change with distance of a Zhejiang highway tunnel were analyzed in this paper.The results show that: the most dramatic change of road illumination happens in the distance and outside the tunnel entrance road in the range of 5m;the effects of natural light illumination significantly reduced inside 10m of the tunnel;and inside the tunnel after 20m, the effects of natural light on the hole is weak.Finally, the methods to improve the road illumination difference of tunnel entrance were studied.
