Something I learned long ago, don't believe everything you here. I am pasting an article that tells the "rest of the story" about the USF article, who created it and why it is so flawed. I am sure the professor that wrote his response to this poor bit of inept research will mind me submitting it on his behalf.

Recently there has been considerable press coverage of a study released by Dr. Barbara-Langland-Orban, an Associate Professor in the College of Public Health at the University of South Florida that argues against the installation of photo enforcement to curb red light running. Regrettably much of the press coverage has identified her report as a study by the University of South Florida, which implies that it reflects the collective wisdom of the University. Since there are thousands of faculty members at USF, the press coverage would have more accurately noted the views as those of Langland-Orban, a USF Associate Professor.


As Director of the USF Center for Urban Transportation Research I feel compelled to offer some contrary evidence. In her latest paper, Langland-Orban cites the National Motorists Association as one of her sources. You owe it to yourself to check out the website of the National Motorists Association. You’ll find they would better be named the national scofflaw association. If you check out their website you’ll find they sells books like “Speeding Excuses That Work”, “Beat Your Ticket: Go to Court and Win”, a full range of radar detectors, and their Guerilla Ticket Fighter CD. Not exactly a credible source.


Her article reports the results of a year-long study, but really it was a synthesis of other studies. Her article correctly notes that there are many engineering countermeasures that can affect crashes at signalized intersections, including assuring signal head visibility, selecting appropriate yellow time intervals, use of an all-red clearance interval, and others. These measures are important and are included in recommended practice by traffic engineering practitioners. While focusing on a couple contrary studies and citing the aforementioned National Motorists Association, she neglects to include in her synthesis the many studies that support the effectiveness of red light running cameras. A recent Iowa State University showed dramatic reductions in both violations and crashes after the installation of red light cameras for both rear end crashes and for right angle crashes. She also omits discussion of the National Academy’s Transportation Research Board report on the Impact of Red Light Camera Enforcement on Crash Experience, which did a comprehensive review of many studies done across the country. They concluded that a majority of jurisdictions that have implemented camera enforcement reported downward trends in red-light running violations and crashes, especially the more severe types.

The USDOT Federal Highway Administration and the 15,000 member Institute of Transportation Engineers endorse the proper implementation of photo enforcement, which includes site by site studies and implementation of other engineering countermeasures, oversight of photo enforcement by public agencies, and a strong public education program.

Driving on our roads is a privilege and we shouldn't hesitate to ticket those who violate basic rules of the road, notably failure to stop at a red traffic light, which endangers all of us.
