Abstract

This article discusses the use of adaptive roadway lighting against the backdrop of the necessity of reducing the energy consumed by passive sources. Adaptive lighting typically involves the use of a regulatory mechanism that allows for minimizing power consumption of such lights during non-peak hours. Lighting levels are typically determined by the amount of pedestrian conflict/activity in a given area. However, such levels are highly variable despite general predictability based on a few factors that include the hour or night, the day of the week, the season, or location of the area in question. Perhaps the most technically sophisticated systems allow operators to remotely control and monitor nearly all aspects of the lighting system in question. Some such features include the operating status of luminaries in a given system, the lumen output, and also potential expansions into wireless technologies. The article also provides brief examples of where such systems are being implemented.
