Study was undertaken to provide improved understanding of night motorist's inherent and typical handicaps; principles of roadway lighting, engineered for benefit of night motorist's visibility; following recommendations are made -- to use Short Cutoff control of loss of visibility due to DVB (disability veiling brightness) which detracts from overall visibility effectiveness of roadway lighting system, improved light distributions that are within limits of Short Cutoff vertical control, and visibility effectiveness of 100 lumen/w high-intensity sodium lamp; comparative effectiveness and costs of roadway systems.
