Tunnels commonly create bottlenecks in traffic flow because of a change in cross-sectional width and a discontinuing of road shoulders past the portal. The effect of these restrictions can be congestion and high accident rates unless an adequate lighting system is provided to reveal the locations of walls and curbings. The problem is most accute in daytime, when drivers make the transition from a brightly illuminated exterior roadway to the tunnel interior with a much lower luminance level. To facilitate the design of a lighting installation which will allow for this transition, it is convenient to consider tunnels as being made up of 5 zones: 1) the approach zone, 2) the threshold zone, 3) the transition zone, 4) the interior zone, and 5) the exit zone. Each of these zones has specific lighting levels and lengths depending on the tunnel wall materials, tunnel dimensions, wall color, portal landscaping, and traffic characteristics. Luminance requirements can vary from 100 fL to 250 fL depending on the tunnel orientation with the sun.

The lighting of both exteriors and interiors is a field within electrical and lighting engineering, where important technological changes have been taking place oriented towards environmental sustainability and energy efficiency. LED technology has been gradually gaining ground in the world of lighting over other technologies due to its high lighting and energy efficiency and savings. However, some problems related to overheating or associated regulation are emerging. This has prompted the search for new, more efficient, and sustainable forms of lighting. This book presents successful cases related to energy efficiency and lighting that may be of great interest to those trying to enter the world of scientific research.

This guide replaces the 1984 publication entitled An Informational Guide for Roadway Lighting. It has been revised and brought up to date to reflect current practices in roadway lighting. The guide provides a general overview of lighting systems from the point of view of the transportation departments and recommends minimum levels of quality. The guide incorporates the illuminance and luminance design methods, but does not include the small target visibility (STV) method.
