My friend said that she was driving on Broadway last night and saw a bunch of blue lights on video cameras pointed at intersections.  Are these speed traps or cameras snapping pictures of people who run red lights?

Because if the intersection needs a light, then the eventual green light would be helpful for the bicycle or motorcycle.

If traffic is light enough that drivers can easily get across without too long of a wait, even at busy times of day, there shouldn't be a traffic light in the first place.

Since bicycles and motorcycles are small and easily maneuverable, they can safely cross through gaps in traffic that would be unwise for the driver of a car. They can also cross just part of an intersection at a time, if necessary.
