The subject of different types of cameras came up briefly in this thread, but I wanted to summarize what actions we should be taking.
Washington DC now has seven different purposes for traffic enforcement cameras. We have the traditional red light camera, the traditional speed camera and speed cameras at intersections.
We also have:
gridlock cameras which ticket you if you can not clear an intersection by the time the light is green for the opposing traffic;
stop sign cameras which ticket you if don't come to a complete stop at a stop sign;
pedestrian right of way cameras which ticket you if fail to stop for a pedestrian in a crosswalk; and
oversized vehicle cameras which will ticket trucks on restricted routes.

Is there agreement that gridlock, stop sign and pedestrian right of way cameras should be entered the same as red light cameras? Is there agreement that oversized vehicle cameras should not be mapped?
