Counterpoint: The Insurance Institute for Highway Safety Study Actually Found Cities Using Red Light Cameras Had Higher Red Light Running Fatality Rates

Summary Information

A January 2012 study conducted by the University of South Florida (USF) disagreed with findings in a February 2011 Insurance Institute for Highway Safety (IIHS) report that evaluated the impacts of photo enforcement on red light running fatality rates in major U.S. cities. The IIHS report examined fatality rates in localities with and without photo enforcement between 1992-1996 (before period) and 2004-2008 (after period) and reported that fatal "red light" crashes, defined as any intersection crash except a rear end collision, decreased 35 percent in cities with photo enforcement, but only decreased 14 percent in cities without photo enforcement. USF researchers argued that the IIHS study focused on city-wide data, not specific to camera sites, and did not address exogenous factors such as changes to public policy, engineering improvements, and other trends that also improve safety.

FINDINGS

Reinterpreting the results of the February 2011 study conducted by IIHS, USF researchers indicated that the before and after data actually show that cities using red light cameras had a 25 percent higher rate of "red light" fatalities compared to cities that did not use red-light cameras.
