Most people don’t like them. Privacy advocates abhor them. But, really– how many things can you name that save lives AND generate revenues for cash-strapped local and state governments? Red-light cameras are one such item.
A recent study by the Insurance Institute for Highway Safety has shown that red-light cameras saved 159 lives over a four-year period in the 14 large U.S. cities where the study took place. The scientists claimed that more than 800 traffic fatalities would have been prevented during the course of the study if the cameras had been deployed in all large U.S. cities.
The scientists compared fatal car crash rates in U.S. cities with populations of at least 200,000 for two four-year periods: 1992 to 1996 and 2004 to 2008. They excluded cities that had already deployed red-light cameras in the earlier period, and cities that instituted cameras during the later period.
In the 14 cities that used red-light cameras during 2004 to 2008, the rate of fatal red-light running crashes was 35 percent lower than in 1992 to 1996. The crash rate did drop in cities that never deployed camera programs, but only by 14 percent.
Based on these data, the scientists determined that the rate of fatal red-light running crashes was 24 percent lower in cities with cameras in 2004 to 2008 than it would have been had they not deployed the cameras. In fact, the benefits of red-light cameras were actually larger than this. The rate of all fatal crashes at intersections with signals (not just red light running crashes) dropped by 14 percent in cities that deployed red-light cameras, whereas it increased by 2 percent in other cities.
