• Fixed intersection lighting should enhance intersection visibility while minimizing glare.
• Select a pole height, luminaire type, and luminaire cutoff that provides sufficient, uniform coverage through the intersection without exposing motorists to excess glare. Luminaire mast height and the light source’s beam pattern directly influence the coverage, uniformity, and intensity of illuminance measured at the pavement. Higher masts provide broader but less intense coverage. Table 21.4 lists recommended illuminance levels for intersections of continuously lighted streets with R2 or R3 pavement classifications.
• Figures 21.1(a) and 21.1(b) illustrate traditional and alternative intersection lighting layouts, respectively. Traditional layouts do a good job of lighting conflict areas but at the expense of pedestrian visibility. The alternative layout increases pedestrian visibility but does less well illuminating conflict areas.
• Partial lighting systems can be used if intersecting streets are not continuously lighted.
