There have been many studies over the years about the effects of red-light cameras. But for the first time, a new study by the Insurance Institute for Highway Safety (IIHS) takes a look at what happens when cities end their programs.
This study shows pretty clearly that red-light cameras can save lives. However, the IIHS notes that there are actually fewer active programs than there were at the peak in 2012. In 2012 there were 533 cameras in service while in 2015 there were 467.
The IIHS says this is the first time an organization has studied the effects of ending programs instead of starting them.The organization first compared 57 cities that started and continued programs from 1992 to 2014 with 33 cities that don’t have any. In the end, cities with red-light cameras had 21 percent fewer deaths related to collisions with red light runners and 14 percent fewer deaths from other crashes than cities without cameras.
The IIHS discovered that doing away with the cameras resulted in a 30 percent increase in deaths due to crashes with red-light runners and a 16 percent increase in deaths from other collisions.
