The Effects of Rurality, Proximity of Other Traffic, and Roadway Curvature on High Beam Headlamp Use Rates

This paper looks at the use of high beam headlamps and whether use rates change based on various factors including: rural or urban location, straight or curved roadway segment, proximity of other vehicles, and the amount of roadway lighting. Video field photometry data was collected at 20 sites in Ann Arbor, Michigan during May-August 2015. It was found that vehicles at rural sites were more likely to use high beams than vehicles at urban sites. However, rates overall were much lower than expected for both rural and urban sites ranging from 0.9% to 52.9%. It is suggested that advanced technologies such as high beam assist could help address underuse of high beams.
