EFFECTS OF MARKER TYPE, VIEWING ANGLE AND VEHICLE VELOCITY ON PERCEPTION OF TRAFFIC MARKERS IN A DYNAMIC VIEWING SITUATION

THE EFFECTS OF TWO TYPES OF "STOP" MARKERS, NINE ANGLES OF ORIENTATION, FOUR VEHICLE VELOCITIES, AND THEIR INTERACTIONS WERE STUDIED IN A DYNAMIC TRAFFIC SITUATION. THE EXPERIMENT WAS CONDUCTED IN THE LABORATORY BY VARIATION OF THESE FACTORS IN SHORT (10-SEC.) FILM CLIPS. AN ANALYSIS OF VARIANCE PROVED THE FACTORS OF MARKER TYPE, VIEWING ANGLE, AND THEIR INTERACTION TO BE STATISTICALLY SIGNIFICANT, WHILE THE FACTOR OF VEHICLE VELOCITY AND OTHER INTERACTIONS PROVED INSIGNIFICANT. AT MOST ANGLES OF ORIENTATION AND AT ALL VEHICLE VELOCITIES, MORE CORRECT RESPONSES WERE PRODUCED BY THE CURVED MARKER THAN BY THE TWO- DIMENSIONAL MARKER.
