Sustainable Traffic Signal Development

This article from the US describes the complexity of traffic signal design and installation. It includes a mention of the principles of universal design for future design innovations and states: “Agencies should be seeking solutions that benefit as many sectors of society as possible, thus making the end solution more sustainable. Using “Universal Design” design principles, wheelchair ramps not only benefit those in wheelchairs, but those with minor disabilities, aging pedestrians who have limited mobility, and parents pushing strollers. Thus, applications like heating ramps in areas that have freezing temperatures can be thought of as a universal solution aiding as many users of the signalized intersection as possible.” Go to this link to read this informative article.
