The IIHS Study on Red Light Cameras: What Can We Learn?
The Insurance Institute for Highway Safety (IIHS) has conducted a study on red light cameras and their impact on traffic safety. The results of the study suggest that getting rid of red light cameras could lead to an increase in deadly traffic crashes.
According to the IIHS, cities that have ended their camera programs have seen a significant increase in red light running crashes, which went up by nearly a third. This is compared to cities that continued with their camera programs, where there was no notable increase in these types of crashes.
The study also found that all kinds of crashes at intersections with traffic signals went up 16% in cities that got rid of cameras. This suggests that red light cameras not only deter drivers from running red lights but also influence other behaviors by drivers.
However, it's worth noting that while red light cameras can increase the likelihood of rear-end crashes, these types of crashes are more likely to be minor with fewer fatalities and injuries compared to T-bone crashes.
The city of Dayton, Ohio, rebooted its traffic camera program after a two-year hiatus during which time there was no camera system in place. The result was a 40% increase in red light running crashes. Officials expect the opposite trend when they re-install the camera system.
Russ Rader, who works for IIHS, believes that lives will be lost in communities that remove their camera systems without a clear safety benefit. He also notes that certain cities' attitude towards red-light cameras is often driven by dollars, rather than a genuine concern for public safety.
Opponents of red light cameras have proposed solutions such as longer yellow lights to give drivers more time to slow down. Researchers at Virginia Tech found that increasing the length of a yellow light by even half a second can dramatically decrease the number of crashes at an intersection.
In response to these findings, the Florida Department of Transportation has opted to lengthen yellow lights at all red-light camera intersections in order to promote safety and squash any lingering suspicions about ticket revenue.
National safety organizations have been created to provide guidelines and instructions for planning, implementing, and evaluating red light camera programs. The checklist released by these organizations includes recommendations such as placing cameras at dangerous intersections, monitoring safety data, and posting signs to alert drivers that cameras are in operation.
The key to a successful red light camera program is to prioritize public safety over revenue generation. This means using the money collected from cameras exclusively for traffic safety programs and ensuring that the system is implemented in a way that benefits the community.
As Dr. Rader notes, more people are alive today as a direct result of these devices. The Bone Marrow Donor Registry is an example of how technology can be used to save lives. By signing up to become a bone marrow donor, individuals can help patients around the world find life-saving transplants.
