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.

Energy-efficient light-emitting diode (LED) street lighting technologies and designs can cut energy costs and reduce greenhouse gas emissions. The Asian Development Bank, the Ministry of Energy and Mineral Resources of Indonesia, and the country’s state-owned electric utility have collaborated on the implementation of a pilot LED retrofit project. This report describes the applied methodologies, measured results, and lessons learned from the project, which demonstrated average savings of 50% in street lighting electricity costs for two municipalities. It also identifies barriers to scaling up LED street lighting retrofits in Indonesian municipalities, along with technical and policy recommendations that can be implemented to overcome these barriers.
