CAR AND TRUCK REAR LIGHTING AND SIGNALING: THE APPLICATION OF RESEARCH FINDINGS

Rear lighting and signaling systems can be improved by functional separation of lamps and color coding. These techniques will also improve system integrity when there is a malfunction, such as a bulb failure. Intensity requirements for signal lamps differing in color and area are derived by subjective tests in day and night. The findings confirm the need for greater intensities in the day than night, and that lamp areas should be considered. Truck rear-end collision data show the need to aid the driver in detecting changes in headway and relatives speed. Theoretical and experimental findings relating to this problem are discussed, and a rear-mounted speed display is suggested. The findings of a study concerned with an accelerator release signal are presented. Characteristics of an improved rear lighting and signaling system are presented. /Author/
