When I was a kid, in Quebec, traffic lights were color-blind friendly; they used shapes and color and orientation. They arranged the lights horizontally, like this: [R] <Y> (G) [R] For stop, you'd get two red squares. Wait was a yellow diamond usually on the left side, and go was a simple green circle on the right side. If you could only go in a few directions, they'd list them out with green arrows. Seemed like a great system to me but I don't see it in use as much any more. Perhaps it was too expensive to manufacture custom lights for just one province.
