Abstract

This research had as a basic objective the evaluation of high intensity reflective sheeting manufactured by the Minnesota Mining and Manufacturing Company for use on overhead sign installations without external illumination. The effects of height above the roadway, angle of sign tilt with respect to the vertical, headlight configuration, and vehicle approach speed on sign legibility distance for both an externally illuminated sign and a high intensity reflective sheeting sign were measured.
