IES RP-8-00:2000 Edition

RP-8-00 American National Standard Practice for Roadway Lighting This
Recommended Practice provides the design basis for lighting roadways,
adjacent bikeways, and pedestrian ways. It deals entirely with lighting
and does not give advice on construction. It is not intended to be applied
to existing lighting systems until such systems are redesigned. This
Practice revises and replaces the previous edition which was published in
1983 and reaffirmed in 1993.

Roadway lighting is intended to produce
quick, accurate, and comfortable seeing at night that will safeguard,
facilitate, and encourage vehicular and pedestrian traffic. The proper use
of roadway lighting is also associated here with certain economic and
social benefits including a reduction in nighttime accidents, aid to the
police, facilitation of traffic flow, and the promotion of business during
nighttime hours.
