How would a signal "recognize" a bicycle? There's no way - it would be subject to false positives all the time or wouldn't work at all (car ones rarely - if ever - throw a false-positive).

Makes the most sense to have a "walk" button accessible to bicyclists.

bofdem, the common methods of detecting traffic (inductive loops, video detection, and thermal detection) all support bicycles, though they sometimes need to be tuned. In fact, they are "supposed" to since bicycles are considered vehicles. There is a way; they can and do. Google it.

I don't install or fix signals dude. Tell the government to "Google it" and see how far - or arrested - it gets you.

On topic, the intersection is a s--t show and nothing "automatic" or "detection" related has worked. Google that, bro. Then Google GDOT.

Try using a road that has a bike lane instead which north ridge or Roberts is neither. Maybe that's why the lights hate you.
