ASCERTAINING THE EFFECTS OF ATMOSPHERIC FACTORS DURING VISUAL DETECTION EXPERIMENTS IN AUTOMOBILE HEADLIGHTING

This study is concerned with the determination of the influence of atmospheric extinction during automobile headlight experiments. It is evident that this influence can be important before it becomes visually apparent. The methodology of roadway reflectance measurement employing a target substitution technique is presented. Additionally, some theoretical consideration are presented in conjunction with the target substitution method when direct measurement of the extinction coefficient is not possible. /Author/
