I would think you'd specifically want to avoid displaying lights of the same color as "go" for auto traffic, for purposes other than telling auto traffic to "go". So I'd be inclined to avoid green for pedestrian "go", if I were designing such a system. But maybe that's not actually a problem, IDK.
> The icons displayed (hands) are confusing too: the rest of the world uses an icon of a man walking or standing.
Is a hand held up, palm-out, not a signal for "stop" in places other than the US or Canada? I wouldn't assume it's universal, but I'd expect it's got broader reach than that.
Besides, again, I'd personally assume it'd be better to have very different icons for "walk" and "don't walk". Not two different depictions of a person.
