Description

ANSI Approved
Approved American National StandardThe purpose of this Standard Practice is to provide recommendations for designing new tunnel lighting systems, and it is not intended to be applied to existing lighting systems until such systems are redesigned. It has been prepared to advance the art, science, and practice of illumination as it pertains to tunnel lighting in North America.

Lighting is added to vehicular tunnels to enable a motorist to maintain speed and safely navigate. Tunnels may require considerably different treatment of the threshold zone luminance values, depending on variables such as geographic orientation, geometric design, traffic volume, traffic speed, service levels, light source used, and modes of light application.

Treatment of tunnel portals, wall and ceiling surfaces, and selection of lighting equipment, as well as light sources, maintenance, and lighting economics, are also reviewed and assessed.
