His research expertise is mainly in human vision and psychophysics. Much of Dr. Flannagan’s recent work has concentrated on the analysis of crash data to assess the likely safety effects of advanced adaptive headlighting and night vision systems, and on field methods for testing and evaluating these systems. The systems he has worked on include adaptive driving beams (ADB), which replace traditional high-beam and low-beam headlights with fully adaptive multiple-LED systems, and innovative signal lamps for automated vehicles. His work has been supported by many vehicle manufacturers, their suppliers, the Society of Automotive Engineers, and the U.S. Department of Transportation.
