Road lighting covers the most significant part of city lighting in our country as in the whole world. While a correct road lighting solves the chaos occurring in transportation, it paves the way for smooth inner-city traffic flow.

It is required to provide safe driving and visual comfort for the drivers in order to be able to decrease the number of accidents at the evening hours. Excessive lighting causes accidents as well as insufficient road lighting, and it also causes the wastage of electrical energy. Correct road lighting, for well visibility of objects on the road and for vision comfort of the drivers, is possible by ensuring an even luminance distribution on road's surface.
