To study the impacts of vehicle headlights on luminance contrasts of targets located on the road.
Experimental measurements were made on a highway to investigate the contribution of halogen and high-intensity discharge headlights to road lighting.
- The measurement results indicate that in general, the use of vehicle headlights, in the presence of road lighting, does not improve the luminance contrasts of targets located on the road.
