The mesopic luminance region lies between the photopic and scotopic and covers a wide range of lighting applications e.g night-time traffic conditions. It is known that neither V(λ) or V′(λ) alone are representative of the eye’s spectral sensitivity in the mesopic region. The objective was to find out the effects of light spectrum on visibility in road lighting conditions.
The work focused on lighting dimensioning and lighting quality of road and street lighting. The work was based on measuring and analysing road and street lighting and on studying visual performance in varied road lighting and laboratory conditions.
