Because RP-8-18 consolidated multiple practices, it covers almost every imaginable outdoor public space: Continuous Roadways & Highways

The ANSI IES RP-8-18 PDF provides numerous benefits for roadway lighting design and installation, including:

The standard classifies roadways by their function and traffic volume. High-speed, limited-access highways require strict luminance control to prevent driver fatigue and ensure long-range visibility. Local streets focus more on illuminance to illuminate sidewalks and intersections. Intersection and Crosswalk Lighting
