Red light cameras saved 159 lives in 2004-08 in 14 of the biggest U.S. cities, a new analysis by the Insurance Institute for Highway Safety shows. Had cameras been operating during that period in all large cities, a total of 815 deaths would have been prevented."The cities that have the courage to use red light cameras despite the political backlash are saving lives," says Institute President Adrian Lund.
Looking at the 99 U.S. cities with populations over 200,000, the researchers compared those with red light camera programs to those without. Because they wanted to see how the rate of fatal crashes changed after the introduction of cameras, they compared two periods, 2004-08 and 1992-96. Cities that had cameras during 1992-96 were excluded from the analysis, as were cities that had cameras for only part of the later study period.
The researchers found that in the 14 cities that had cameras during 2004-08, the combined per capita rate of fatal red light running crashes fell 35 percent, compared with 1992-96. The rate also fell in the 48 cities without camera programs in either period, but only by 14 percent.
Based on that comparison, the researchers concluded that the rate of fatal red light running crashes in cities with cameras in 2004-08 was 24 percent lower than it would have been without cameras. That adds up to 74 fewer fatal red light running crashes or, given the average number of fatalities per red light running crash, approximately 83 lives saved.
