The technology could be better used
The technology used to issue the citations could, instead, be used to make the intersections work better. Unless traffic is extremely heavy, it's best to clear the intersection from each direction before allowing the next set of vehicles to begin moving. In my city, they installed optical sensors to replace the road-embedded sensors, and they were doing a really good job of keeping traffic moving. Then they put up red-light cameras, and at one particular intersection they put the lights on a regular (short) cycle instead of leaving it alone. This ensured that drivers would be frustrated at having to wait through several cycles and be tempted to run the lights.
After the citizens demanded the cameras be removed, the city complied. Unfortunately, that particular intersection still has short-cycling lights, and is often backed up over a block in one direction, and all the way onto a highway exit in another. They forgot that they had it right before.
