Abstract

Rear-end collisions are about 25% of all highway crashes, but are a class of collision which is probably more amenable for treatment than others. During the last decade a substantial number of studies have been completed concerned with the effectiveness of vehicle rear-lighting and signaling. Additional studies are presently being conducted, including some field tests to evaluate the rear-end accident reducing potential of some experiment concepts. The paper provides an overview of some of the marking and signaling research work carried out since 1967, emphasizing the author's work, using analytical methods, simulators and field testing, and presents data on such topics as: separation of lamps by function and color, day-night intensities of signal lamps, coasting and deceleration signals and other specific signaling concepts, and accident data analyses. On the basis of these data the information required by drivers of following-vehicles to avoid rear-end collisions is suggested, including the means of displaying such information by the vehicle rear lighting and signaling system.
