Energy-Saving LED Traffic Lights Potentially Dangerous in Snow Storms (treehugger.com)

A very interesting article. I wonder though if the same technology that is used on the windshields of cars can be applied to the glass portion of the traffic lights. Only in this case, traffic controllers would be able to remotely turn the heat on to melt the ice/snow during winter. This way, they would be able to mitigate the energy costs discussed about in the article.
