Arizona had the traffic spybot cameras for a while but we kicked them out because the company that owns them was making the big profits and they caused more freeway and local road problems than they could justify.
There are still cameras at major intersections looking for red light runners but the regular speed monitors are gone. 
California outlawed automatic speed ticket-issuing cameras years ago. Probably because our legislators and off-duty cops are some of the worst speeders around.
The city that I used to work for had several "red-light" cameras that sent out tickets to anyone blowing through a red light, or (and this was a real issue) turning right at a stop light without coming to a complete stop first (the infamous "California stop"). These cameras were installed in the name of "safety" via a contract with a private company that installed, owned and operated the cameras.
But after about 10 years, the city removed the cameras when a study found that the private company was making all of the money from these "safety" improvements and, as drivers became "safer" by stopping first before making a right hand turn, the city had to make up the profit that the private company was guaranteed when the cameras were installed. It was then that the voters found out that the cameras were really about revenue and not so much about "safety".
