1. I would also look at night time sight lines and backgrounds in downtowns. At night there are many neon and other coloured lights from stores, displays, etc. that can be confused with or obscure traffic lights. I don't know what power the cities have in getting sign owners to reposition their illuminated signs but at least they could try to work cooperatively with them.
2. An early problem with LED traffic lights is/was snow accumulation. Incandescents ran hot enough to melt snow as it fell on the light. But LEDs run much cooler. How has this issue been addressed?
