Standard Spacing for Roadways Other than Freeways

To determine the required illumination levels for roadways other than freeways, use the tables in Section 2 of this chapter, the
AASHTO Roadway Lighting Design Guide
, or
ANSI/IES RP-8-14, Roadway Lighting
. An illumination program capable of calculating luminance or illuminance levels is required to determine if adequate illumination levels have been achieved.
