The lights have been blinking yellow for a decade or two. I could look out my window and yell it is not a stop for the people stopping for it. Today they made the light actually function and added cameras.

Picture taken out my window.

    Not every camera is an ALPR. The ones mounted above the signal heads like that are for computer-vision-based vehicle detection for signal phasing and timing (i.e. as an alternative to an inductive loop). AFAIK they’re only hooked to the traffic signal controller and don’t really provide video to any external system, but even if they could, they’re not pointed in the correct direction to be able to capture the sort of information an ALPR does. The cameras on top of the signal heads mostly just see the roofs of the cars, while ALPRs are mounted a lot closer to the ground so that they can image the fronts and backs of the cars and capture stuff like the license plate and the driver’s face.

    The truly sad part is you had to yell at people how to use a blinking yellow light. Isn’t that taught in driving school and on the written test?

      I think ALRP mass data collection of your persons by a private corporation is vastly more sad.

      But as other responded these do not seem to be ALRP or Flock cameras

      I’m colourblind and can’t tell a blinking yellow light apart from a blinking red light, so I woukd treat it as a red. This is only for those single light intersections. If there’s three lights but set to blink (sometimes this happens in the middle of the night) I can look at the position once I’m close enough.

          Yellow and red mean almost the same thing, so it doesn’t really matter. And with normal lights, yellow is always the middle, and red is very easy to tell apart from green. I would actually say green is closer to white and is the easiest to distinguish from the others.
