LRC research is sponsored by NHTSA, Philips, AL, GE, GM, Hella, Osram-Sylvania, Philips-Lumiled and Visteon. Bullough gave a high-class presentation about glare at the DELRIS congress (see picture below).
Driving Vision News: You said that after studying roadway glare for two years, your rough prototype blocks a measured slice of an auto’s light beam projecting into the other lane. What do you mean?
John Bullough: The researchresults were published in the NHTSA report “Investigation of Safety-Based Advanced Forward-Lighting Concepts to Reduce Glare.”
The module we used in our tests was not fundamentally different in concept to those such as the “segmented shutter” design described by Shadeed, Wallaschek and Mojrzisch (2007) from the University of Paderborn or the variable cutoff line described by Decker, Himmler and Amsel (2007) from Hella, or similar ideas from other manufacturers.
DVN: Who is the initiator of this work?
J.B.: This work is funded by $890,000 from the NHTSA. Glare is believed to be a major reason the traffic fatality rate is about three times higher at night.
