Traffic Light of the Future

[LumbermanSVO]

I thought the same thing until I learned more about. The common problem you run into is cities will not time their yellows correctly according to the formulas. This is something that is common problem on those too short of yellows. I bet those lights you have a problem with are to short.

But light I said yellow timing has nothing to do with speed of traffic.

I'm very familiar with the timing issues with yellow lights, especially when mixed with cameras. It takes twice as long for a big truck to stop as it does for your average pickup/SUV so driving slower helps a lot.
