EFFECTS OF SIGN ILLUMINATION ON DRIVER BEHAVIOR

This study's purpose was to determine the effects on driver performance of illuminating overhead guide signs. The method used was to analyze erratic driving maneuvers at three successive signs, both before and after their illumination. No change in traffic performance attributable to sign lighting was measured. The test site may have been so complex that lighting signs alone was insufficient to produce practically significant operational improvements. Additionally, erratic maneuver counting may not have been a sensitive enough method to detect changes in performance. Subjectively, however, the illuminated signs were judged to be an improvement because they provided noticeably earlier recognition time and longer reading and comprehension times, thus increasing driver comfort and safety.
