the recent discussion on the flashing yellow arrow reminded me of the new set up my town got on the eastern part of the city.
Apparently, ODOT funded new traffic lights on state route 95 near the US 23 junction. With the new lights came cameras that are, supposedly, setup to monitor traffic flow and adjust the lights so the timing helps keep traffic moving.
Some think they’re actually red light cameras, but I read that they must inform you of the cameras. Also, house bill 69 pretty much outlawed red light cameras in Ohio

Are there any cities out there that have these cameras like we do? Do they really help traffic flow?
