Abstract
The study proposes a method of electrical lighting calculation for a road tunnel, which allows estimating locations of selected luminaires providing the required road surface luminance distribution in the areas of vehicle driver adaptation while driving through a tunnel during daytime. The method is based on the adopted concepts of saturation curve and luminance saturation zone which are used for building of a step curve approximating the set zonal distribution of luminance. The basic terms of the method and the calculation algorithm as well as an example of calculation of luminaire locations in the tunnel luminance zones illustrated by comparison of estimated and pre-set luminance distributions are presented.
