Alternative Title:
Visual performance and safety benefits of adaptive driving beam headlighting systems
It has been understood for many years that driving above certain speeds at night while using low beam
;
headlights can result in insufficient visibility to respond to hazards on the road. As new vehicle
;
headlighting technologies emerge, the practicality of intelligent, adaptive high-beam functions has
;
increased so much that these systems are now commercially available in many parts of the world. These
;
technical developments in turn invite questions about the optimal photometric performance of high beam
;
headlights. One important barrier to the more frequent use of high beam headlighting systems has been
;
concerns about creating glare to the drivers of oncoming and preceding vehicles. If it can be demonstrated
;
that adaptive high-beam control can provide acceptable glare control, it may be possible to question the
;
need for the current limits on the luminous intensity of high-beam headlights. In this report, visual
;
performance analyses are summarized that allow the evaluation of the potential benefits of increased
;
luminous intensity on forward visibility, and potential implications for driving safety are discussed.
