Solar-Powered Traffic Systems Put You in the "Green" While Saving "Green"

This article describes the use of solar power for general traffic signalization in terms of economic and ecological benefits. It is noted that, on occasion, signals to be lighted, while being near a source of power, might need complicated remediation that would be cost prohibitive. Without working around sprinkler lines, destroying concrete, or maneuvering through other obstacles, such signals can be easily lit using a photovoltaic cell. Some of the projects the article suggests for these solar-powered signals include school zone indicators, continuous duty flashers, preemption repeater systems, traffic sensor and camera systems, radio repeater systems, in-roadway lighting systems (IRWL), and transit shelter lighting. The benefits in terms of reducing carbon emissions are also outlined.
