The Roadway Lighting Efficiency and Power Reduction Guide reviews options and provides guidelines for light reductions and energy efficiency practices. It provides information to road jurisdictions, designers, consultants, and suppliers on how to assess, evaluate, select, and deploy energy-efficient roadway lighting while reducing power consumption and cost.

The information presented in the Guide was gathered from international research and studies conducted by organizations such as the US Department of Energy, the Illuminating Engineering Society of North America, the Commission Internationale de l'Eclairage (CIE), the US Federal Highway Administration, and LightSavers Canada.As of 2013, information about the assessment, design, selection, and deployment of energy-saving lighting technologies has been unavailable. As a result, there has been a resistance in applying these technologies due to lack of understanding about the risks and benefits. The objective of the Guide is to provide the information necessary to allow the selection and deployment of energy-efficient roadway lighting based on the findings that the energy-saving lighting technologies and controls have significant energy-saving benefits. The Guide concludes that improving energy-efficiency can be achieved through the use of new roadway lighting sources such as LED's.

The Roadway Lighting Efficiency and Power Reduction Guide is a supplement to the TAC Guide for the Design of Roadway Lighting (2006).  Keywords: Economics and Administration; Colour, Cost, Efficiency, Energy, Evaluation (assessment), Light emitting diode, Lighting (street), Luminance, Risk assessment, Selection
