INTERACTION BETWEEN FIXED AND VEHICULAR ILLUMINATION SYSTEMS

THIS REPORT SUMMARIZES THE TOTAL RESEARCH EFFORT, WITH EMPHASIS ON THE FINAL PHASE WHICH COVERED A SERIES OF EXPERIMENTS RELATING DRIVER AND PEDESTRIAN GAP-ACCEPTANCE TO ILLUMINATION LEVEL, UNIFORMITY RATIO, VEHICLE LIGHTING AND VEHICLE SPEED. THE MAJOR CONCLUSIONS OF THE RESEARCH ARE THAT DRIVERS' RESPONSES TO A ROADWAY OBSTACLE ALMOST ALWAYS IMPROVED IN THE PRESENCE OF INCREASED ILLUMINATION, LEFT TURNING DRIVERS AND PEDESTRIANS WILL UTILIZE AVAILABLE LIGHTING TO MAXIMIZE SAFETY, AND GAP-ACCEPTANCE PERFORMANCE VARIABILITY INCREASES WITH ILLUMINATION. PARKING LIGHTS RESULTED IN AN OVERESTIMATE OF SEPARATION DISTANCE IN THE INTERSECTION CROSSING SITUATION. /AUTHOR/
