The Contribution of Vehicle Headlights to Visibility of Targets in Road Lighting Environments
نویسندگان
چکیده
In this paper road lighting measurements were made 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. The impacts of vehicle headlights are highly dependent on the vehicle, headlights type, target reflection factor, position of the target, position of the vehicle and road lighting installation. The effects of HID headlights on targets luminance contrasts were more significant compared to the ones of halogen headlights. Copyright © 2008 Praise Worthy Prize S.r.l. All rights reserved.

Driving at night is a dangerous activity that necessitates maximum driver awareness for safe operation of a motor vehicle. A relatively cheap and effective way to increase a driver’s situational awareness is by proving the best view of the road and existing obstacles possible. Until the perfection and proliferation of night vision systems in cars this will be accomplished using headlights. Ther...
متن کاملThe Accuracy of Drivers’ Judgments of the Effects of Headlight Glare: Are We Really Blinded by the Light?
Headlights must balance two conflicting goals: maximizing visibility for the driver and minimizing glare to other drivers. Yet consumer complaints about headlights tend to focus on glare and not on poor visibility – a known casual factor of nighttime roadway crashes. These reactions may help to explain why drivers tend to underuse high beam headlights. This study explored the relationships amon...
متن کاملProgrammable Automotive Headlights
The primary goal of an automotive headlight is to improve safety in low light and poor weather conditions. But, despite decades of innovation on light sources, more than half of accidents occur at night even with less traffic on the road. Recent developments in adaptive lighting have addressed some limitations of standard headlights, however, they have limited flexibility switching between high...

Very few data have been published that demonstrate the possible benefits to safety from advanced headlighting technologies on nighttime driving safety. By comparing insurance claim information for different vehicle models equipped with such systems, the Highway Loss Data Institute (HLDI) compared vehicles with and without adaptive curve lighting (ACL) systems. Overall, the HLDI data are consist...
