green is not a ground when it comes to traffic lights.
Green is supposed to be the equipment grounding conductor.
They just have had a heck of a time convincing the people that wire the signals that it's not for "GO"..
The IMSA (International Municipal Signal Association) does not recognize green as anything other than an equipment ground, and they write the standards adopted by almost everybody around.
You learn something new everyday. I've always been told that it meant green's Hot, as signals are rarely grounded in the field (by a grounding wire at least.) That's why I make the harnesses/cables for my lights, while a lot of people use 14/3 w/ ground SO cord.
