The cameras, which are being used to enforce traffic laws in more than 40 U.S. communities, photograph vehicles whose drivers deliberately run red lights. Violators then are ticketed by mail. This has changed the way drivers behave with regard to red light running, and now we can document how this behavior change is reducing crashes and injuries. With the well-publicized use of camera enforcement, communities can make signalized intersections much safer. Once the enforcement got under way at city intersections, support increased.
Similar support prevails nationwide.
Opinions about camera use are favorable in communities with and without enforcement programs, according to a recent Institute survey in 10 cities. Despite this support, officials in many U.S. jurisdictions aren't able to implement camera programs. Without explicit authorization, camera use may not be possible.
