It has long been recognized that conventional headlighting, consisting of lower and higher beams, falls far short of meeting the visual needs of drivers at night over the range of speeds and driving conditions that are commonly encountered.New lighting technologies—such as camera-based adaptive lighting, LED matrix light sources, and laser light sources—may be able to provide vehicle lighting that meets the nighttime visual needs of drivers much better than has been possible in the past.Similarly, the rapid growth of so-called naturalistic driving data, and the corresponding growth in methods for analyzing those data, has allowed the visual needs of drivers to be understood better than in the past.This paper presents analyses of naturalistic driving data, the resulting definitions of driver visual requirements, and estimates of possible safety effects that could result from different levels of implementation of new headlighting technologies.
