This annotated state-of-the-art bibliography on visibility assesses the literature on existing standards as well as the various design and environmental variables associated with visibility. It also includes an evaluation of future research needs and trends into the development of a general visibility index, which will provide the method for examining the effective value of color, texture, pattern, contrast, and other variables used in warning devices, signs, labels and markings for the purpose of enhancing safety by better visibility. Some of the topics included are: camouflage, pattern recognition, color contrast, luminance contrast, reflectivity, illumination, background, lighting types, distance and moving objects. The conclusions of this report include a suggested outline of a comprehensive program of study into the visibility concept. The research outline highlights those areas believed to have the greatest near-term potential as well as those requiring longer lead times. (Contract No. 210-76-0116)
