CONSPICUOUSNESS OF CARS OF VARIOUS COLORS

QUESTIONS ARE RAISED PERTAINING TO (1) THE DIFFERENCES IN CONSPICUOUSNESS DURING DAYLIGHT FOR OPPOSING VEHICLES OF VARIOUS HUES, SATURATIONS, AND BRIGHTNESS AGAINST SOME REPRESENTATIVE ROAD BACKGROUNDS, (2) THE DIFFERENCES IN PERCEIVED DISTANCE TO OPPOSING VEHICLES OF VARIOUS HUES AND BRIGHTNESS, AND (3) THE EFFECT OF TURNED ON HEADLIGHTS ON CONSPICUOUSNESS OF PERCEIVED DISTANCE. ON THE ROAD CAR-SIZED PLATES OF VARIOUS COLORS ARE PHOTOGRAPHED (COLOR-SLIDES) FROM 300M DISTANCE. THESE SLIDES ARE SHOWN IN A TACHISTOSCOPE AND THE DETECTION TIME FOR EVERY SITUATION IS DETERMINED. A CAR IS DRIVEN BY THE SUBJECT IN RURAL TRAFFIC. WHEN HE DETECTS AN OPPOSING VEHICLE HE GIVES AN ORAL DECLARATION OF THE REASON FOR DETECTION AND AT THE SAME TIME HE RELEASES THE CAMERA THAT TAKES A COLOR SLIDE OF THE SITUATION. ON A TEST TRACK SUBJECTS ARE REQUIRED TO MATCH THE DISTANCE TO TWO OPPOSING CARS OF VARIOUS COLORS. IN THE SITUATIONS DESCRIBED ABOVE TURNED ON DIPPED HEADLIGHTS ARE COMPARED WITH THE VARIOUS COLORS. /SRIS/
