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.
