Playing devils advocate here: I think the reasoning behind it could be argued that if people dont know which intersections have red light cameras, they are more likely to not run reds at any intersection just in case. Similar to the idea behind [Panopticon](https://en.wikipedia.org/wiki/Panopticon https://en.wikipedia.org/wiki/Panopticon). If the cameras were clearly labeled people might run reds in unlabeled intersections.
