abstract="A study is reported which had 2 objectives: (1) establish minimal levels of sign luminance for various signing applications and situational conditions; and (2) develop an overall structure for identification of maintenance priorities and schedules. The full report of the study (available from National Technical Information Service, 5285 Port Royal Road, Springfield, Virginia 22161; order number PB86-236569/AS) is in 4 sections: overview of the problem of implementing luminance standards and of related issues; discussion of the major factors essential to a computer-based system to implement reflectivity standards; description of decision support system developed as part of the research; description of an evaluation of the system and discusssion of value with respect to several alternative criteria. This article describes the study's approach. The conclusions drawn from the study are listed, and the recommendations emanating from it are presented.<p />",
