The lights in my small Pennsylvania town just got cameras and do seem to be using ML to recognize traffic build-up and optimize dynamically for traffic flow. Pretty cool stuff.

I think the real reason they were installed was because of a new state law that goes into effect this July where you'll be fined if you're spotted holding a smartphone by a traffic cam. Still, the faster light changes are quite welcome.

Wait, what?! I’m at a loss as to the behavior they’re trying to curb with such a law.

EDIT: OIC, it’s not “using a phone near a traffic cam”, it’s “using a phone while driving (even at a stop light) and a traffic cam captures you doing it”.
