Abstract:This report provides information on the design considerations of the embedded highway lighting
design on Interstate-25 in Trinidad, Colorado, in terms of visibility. The information is based on
visibility characterizations of small targets using luminance, illuminance, and contrast calculations as
well as participant input on the detectability of small targets. Experimental conditions included two
different aim angles of the lighting design (forward and cross) as well as two small target colors (red
and blue). When compared to the small target detection distances produced by conventional overhead
lighting systems in previous studies, the research determined that the small target visibility distances of
the embedded lighting design to be shorter by approximately 50%. Adjustments to the spacing, aim,
and breadth of the lighting design are recommended for future research considerations.
Implementation
The results of this research indicate the lighting design is an alternative; however, additional
considerations to the beam angle, beam width, beam height, and spacing may improve the
implementation of the system.
