Upchurch, Jonathan E. and Bordin, Jeffrey T. (1989): A Human Factors Evaluation of Freeway Guide Sign Lighting Systems. In: Proceedings of the Human Factors Society 33rd Annual Meeting 1989. pp. 615-619.

“The objective of the study was to identify a lighting system for freeway guide signs which is more economical and which adequately satisfies motorist's needs in terms of legibility, illumination, color rendition, and other factors. Through the use of technical data and specification review, photometric tests, and computer analyses, ten lighting systems were selected for field testing (10-14 months). Luminance levels, power consumption, maintenance requirements, and lamp life were noted. A human factors study determined legibility distance and rated viewing comfort, lighting uniformity, and color rendition. Senior citizens and young adults were used to detect possible age-related differences. None were noted other than seniors placed more importance on color rendition. It was determined that the differences between the best human factors performing lighting systems and the best regarding economics was only marginal concerning human factors. The most economical system was thus recommended.”
