EFFECT OF SIGN POSITION AND BRIGHTNESS ON SEEING SIMULATED HIGHWAY SIGNS
SIMULATED INTERSTATE GREEN SIGNS OF VARYING BRIGHTNESSES WERE SHOWN TO SUBJECTS AGAINST TYPICAL HIGHWAY BACKGROUNDS. SUBJECTS WERE ASKED TO INDICATE WHICH SIGNS THEY COULD SEE BEST UNDER THE VARIOUS CONDITIONS DEPICTED, AND WERE SIMULTANEOUSLY REQUIRED TO ENGAGE IN AN AUXILIARY TASK INVOLVING FIXATION UPON SMALL RED LIGHTS AT ROAD LEVEL. EXPERIMENTS PERFORMED WERE DESIGNED TO STUDY THE VARIABLES OF SIGN POSITION AND BRIGHTNESS IN RELATION TO EASE OF SEEING SIGNS UNDER SIMULATED HIGHWAY CONDITIONS. /AUTHOR/
