The tunnel lighting must be controlled such that users, both during the day and by night, can approach, pass through and exit the tunnel without changing direction or speed with a degree of safety equal to that on the approach road. Especially by day the human eye needs to adapt to the lower lighting levels in a tunnel. The threshold lighting needs to be controlled such that drivers can perceive obstacles in the tunnel early enough to stop the vehicle.<\/p>\n<p>The requirements for tunnel lighting are determined by the nature of the human eye. How well the eye recognises vehicles and other obstacles in a tunnel depends on the lighting and visibility as well as the reflexion characteristics of the road surface and the tunnel walls. Luminance is the measure representing what a human being perceives as brightness and as such is the main control variable for the tunnel lighting.<\/p>\n<p>Tunnel lighting needs to be adapted to these environmental conditions, following these national and international guidelines:<\/p>\n<ul>\n<li>CIE 88:2004 Guide for the lighting of road tunnels and underpasses<\/li>\n<li>CEN Report CR 14380
