THE LOCATIONS OF HEADLAMPS AND DRIVER EYE POSITIONS IN VEHICLES SOLD IN THE U.S.A.
Information about the locations of headlamps and driver eye positions is important in estimating the performance of a variety of traffic-safety equipment, such as retroreflective traffic signs and markings, rearview mirrors, and headlamps. Driver eye height is also an important factor in determining safe sight distances on vertical curves. However, no comprehensive database concerning the locations of headlamps and driver eye positions exists for the current U.S. fleet. The present study was designed to obtain such information for vehicles currently sold in the U.S. The information was derived from the 15 best-selling cars and the 15 best-selling light trucks and vans. These 30 vehicles represent 52% of all vehicles sold in the U.S. in 1995. For headlamp locations, actual vehicle measurements were made.
