Key Points


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:

- lighting to be provided, operated and maintained at state expense,

- lighting to be provided, operated and maintained at the expense of the local political subdivision,

- lighting to be adjusted at state expense and operated and maintained at the expense of the local political subdivision,

- state participation in continuous freeway lighting by a local political subdivision,

- and lighting proposed by other political subdivisions on state highways.

When designing, installing, programming and maintaining lighting, factors such as light source and intensity and 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.

This article also includes a glossary, a discussion on the preparation of plans and electrical components.
