Nighttime crash rates are higher than daytime rates partially due to reduced visibility. Fixed-source lighting such as a luminaire tends to reduce crashes in urban and suburban areas with concentrations of pedestrians and intersections.
Different policies apply to:
When designing, installing, programming and maintaining lighting, factors such as light source and intensity and [[901.8 Circuiting|circuiting] must be addressed. Guidelines for high pressure sodium luminaire performance and computation of roadway illumination, future lighting and dusk-to-dawn lighting policy are discussed in this article.
