IES RP-8-18 PDF Download

The IES RP-8-18 standard is a comprehensive compilation of lighting design techniques and criteria for roadway and parking facility lighting. It is a revision of the previous versions of ANSI/IES RP-8 and combines several IES standards on this subject.

The standard emphasizes the importance of considering the overall lighting design and not just specific criteria in isolation. It covers various environments where vehicles are present, including tunnels, intersections, and parking lots. The goal is to provide quality lighting that improves motorist visual quality, enhances visibility of hazards, illuminates conflict areas, minimizes environmental impacts of light at night, and promotes energy efficiency.

It is important to note that while this standard provides general guidance for most roadway lighting applications, it may not account for specific local factors or situations that require special treatment. The recommendations in the standard are based on a consensus of roadway lighting experts and do not have legislative authority unless adopted by an authority having jurisdiction.

Although the standard aims to be a comprehensive reference for roadway lighting, additional documents such as electric codes, transportation design guides, and other codes and standards may be necessary for a complete design. The standard also clarifies that it is not intended to establish a basis for civil liability.
