![]() ![]() ![]() When applied to all 57 cities, as well as 22 cities that started and ended camera programs, the lower intersection crash rate translates into 1,296 lives saved during the years the cameras were operational. ![]() In addition, red-light-running fatalities may be undercounted. Drivers may be more cautious in general when they know there are cameras around. However, the analysis shows they reduce other types of fatal intersection crashes as well. After accounting for the effects of population density and unemployment rates, the researchers found there were 21 percent fewer fatal red-light-running crashes per capita in cities with cameras than would have occurred without cameras and 14 percent fewer fatal crashes of all types at signalized intersections.Īs expected, the cameras have their biggest effect on red-light-running crashes. They compared the trends in annual per capita fatal crash rates in those cities with the trends in 33 cities that never had cameras. IIHS researchers looked at the 57 cities of 200,000 or more people that activated cameras between 19 and didn’t shut them off. It also looks at the effect of ending camera programs, something not previously studied. The new study updates that analysis, using a more rigorous design, a larger number of cities and a longer study period. Earlier studies showed that red light camera enforcement leads to declines in red-light-running violations and crashes at camera-equipped intersections, as well as nearby spillover locations.Ī 2011 IIHS study found that in large cities with red light camera programs during 2004-08, there were substantial decreases in the per capita rates of both fatal red-light-running crashes and fatal crashes of all types at intersections with traffic signals. The forum builds on years of research demonstrating the effectiveness of red light cameras. The injuries to the Sebring’s driver included a concussion and pelvis and rib fractures. The pickup was moving at 48 mph as it struck the sedan. In the 2012 crash, the driver of a 2010 Ford F-150 ran a red light in Yuma, Ariz., and collided with a 2007 Chrysler Sebring as it was turning left. Several speakers also cited the importance of consistent data collection and transparency.Īs part of the day’s events, IIHS conducted a demonstration crash that recreated a real-life red-light-running crash in which a driver was severely injured. One way to do that is to keep camera revenues separate from the general fund and dedicate them to traffic safety. Many speakers emphasized the importance of organizing camera programs so that the public understands their value as a safety tool, not as a revenue generator. Representatives of law enforcement and municipal and state governments, as well as highway safety advocates and researchers, spoke. Thursday’s forum, held at the IIHS Vehicle Research Center, was organized to support red light camera programs by focusing on best practices. While programs are still being launched in some places, the total number of communities with red light cameras fell to 467 in 2015 from a peak of 533 in 2012. Cameras increase the odds that violators will get caught, and well-publicized camera programs discourage would-be violators from taking those odds.Īlthough surveys have found strong support for red light cameras in communities that have them, opposition from a vocal minority has led some jurisdictions to shut off their cameras. While traditional police enforcement can help, there aren’t enough resources to station officers at every intersection. Most of those killed are occupants of other vehicles, passengers in the red-light-running vehicles, pedestrians or bicyclists.Īutomated enforcement deters red light running. Red light runners account for a minority of the people killed in such crashes. Red-light-running crashes caused 709 deaths in 2014 and an estimated 126,000 injuries. ![]()
