Miami Beach’s red light cameras likely won’t be going away any time soon.
A study commissioned by the city found that the overall number of T-bone, sideswipe and rear-end crashes decreased at intersections where red light cameras were installed. These intersections saw about 18 fewer crashes per year after the cameras were put in place in 2010, bringing the number of accidents down from roughly 68 a year to 50.
The study, which was conducted by researchers at Florida International University, examined 27 intersections across the island including eight with red light cameras. (A ninth intersection with a camera was excluded because of construction in the area.) Researchers compared the number of crashes in 2008 and 2009, before the cameras were installed, to the number between 2011 and 2013.
The benefits of the cameras extended beyond the intersections where they were present, researchers found. The overall number of T-bone, sideswipe and rear-end crashes also decreased at intersections near the red light cameras, while intersections farther away saw an increase in these types of collisions.
