Study: Red Light Cameras Reduce Crashes in Chicago

A new study has just been published from the Insurance Institute for Highway Safety Highway Loss Data Institute (IIHS-HLDI) on red-light cameras, (IIHS-HLDI Status Report, Vol. 52, No. 7), and their effectiveness in reducing crashes and injuries.

Northwest University conducted a study for the City of Chicago, which IIHS-HLDI cited was “one of the biggest automated enforcement programs in the country” and found that overall, red-light cameras were successful in reducing “injury crashes by 10 percent and angle injury crashes by 19 percent.”

As we reported last year, another study conducted by IIHS-HLDI found that areas with red-light enforcement cameras “reduced fatal red-light running crash rate by 21 percent and the rate of all types of fatal crashes by 14 percent.”

While red-light cameras are still considered controversial in some states, the cameras have shown throughout the years to be an effective deterrent in red-light running. The biggest argument against red-light cameras is that they are usually characterized as just a way for cities to “generate revenue,” but what this recent study also found is that over time, the amount of violations the City issued actually decreased as drivers learned that it is better to obey the law than get fined.

Nothing improves driver behavior more than receiving a citation.

Unfortunately, traffic officers can’t be everywhere at once. Having red-light cameras not only acts as a force multiplier, which can free up department resources for vital emergency services, but they can reduce the amount of red-light running over time by ensuring drivers stop on red.
