: Guidance on employing lighting systems that are easy to maintain and minimize energy consumption. Key Concepts in the Practice

The practice sets limits on "veiling luminance" (glare) and requires specific uniformity ratios to prevent dangerous dark spots on the road. ansi ies rp-8-18 pdf

: Measures the amount of light falling onto the horizontal surface. This remains the standard for complex areas like curves, hills, and intersections where reflecting characteristics are harder to predict.

ANSI/IES RP-8-18 consolidates roadway, parking, and pedestrian lighting guidelines into a single 430-page manual, focusing on luminance-based design for safety and efficiency. The standard integrates modern solid-state lighting (SSL) technology and offers specific design criteria based on pedestrian conflict levels.
