I know the traffic engineer where I live. The city installed LED lights about a year ago, and he predicted the same thing would happen with his. The city planners were so entralled about the energy savings that they completely overlooked the traffic hazard they present in the winter time.
“The city planners were so entralled about the energy savings”
Which they will promptly lose as soon as they get clobbered for their first lawsuit where someone is killed, because the red light design couldnt be seen for being covered in snow.
They could have saved as much money, as well as the cost of the new lights, if they would eliminate about 75% of the traffic lights in the first place. There are way too many traffic lights in many areas. Take a drive up State Road in Parma, Ohio and on into Cleveland. You will stop an average of every 1000 feet.
