Results of analyses of accident data to evaluate the contributory role of headlighting were inconclusive. Reflectance values of various objects in the driver's field-of-view were measured. Pilot studies were made to evaluate test targets, and the results were used to describe desirable characteristics of a test target for use in subsequent tests. A series of headlighting field tests were carried out to develop a reliable field test method, evaluate variables affecting visibility provided by headlamps, and generate data for use in validating a mathematical model. Driving tests were also used to evaluate glare effects of various beams to oncoming and preceding drivers. (Modified author abstract)
