Go for a Philly Cheesesteak? While You're Out be Sure to Mind Those Traffic Lights

In this article authors describe research conducted in Philadelphia where the city has implemented camera enforcement for red light infractions. Specific research is presented into two intersections along the city’s busy Roosevelt Boulevard. Researchers studied the difference in effects between camera enforcement and extending the length of the yellow light in the traffic signal. It was found that, while both systems decreased infractions, cameras were the more effective of the two with a 36 percent reduction and a 96 percent reduction, respectively. The article argues for the utility of camera enforcement and provides the statistic that 800 crash deaths per year are caused by red light infractions as a premise. The authors make it clear, however, that the purpose of such enforcement is deterrence rather than revenue.
