Why isn conventional police enforcement sufficient?
Enforcing traffic laws in dense urban areas by traditional means poses special difficulties and dangers for police. After a violation has occurred in the presence of a police officer, the officer must often times follow the violator through the red light to stop it, this can endanger the police officer, pedestrians, and other motorists. Most communities do not have the resources for police to patrol intersections as often as needed in order to ticket all red light runners. Research indicates that traditional enforcement has an immediate impact, but camera programs work round-the-clock and free police to focus on other enforcement needs.
