The Marshalite, used primarily in Australia, was invented in 1936 by Charles Marshall, it was used from the 1940's through the 70's and seems to me a better alternative to our current traffic lights. Of course there would need to be updates (perhaps some back lighting) but because of the rotary system, one can know when green will turn to yellow and act accordingly. The colors remain in a uniform pattern to account for color blindness, and I would assume less energy is needed to power the dial than to power three individual lights. Unfortunately I don't see this coming back, especially given that the above image is from The Melbourne Museum... how often to objects come out of historical museums to be put back into use?
