Study: Louisiana Red Light Cameras Fail To Reduce Accidents

A brief study published in this month’s Journal of Trauma examined whether red light cameras installed at a Jefferson Parish, Louisiana intersection caused a reduction in the number of traffic collisions. A team of medical doctors from Tulane University examined accident statistics for ten months before and ten months after the activation of cameras on October 24, 2007. The team found no statistically significant reduction in the number of accidents.

“Red light cameras do not seem to prevent traffic collisions at this monitored intersection,” the study found. “Alternative means of injury prevention must be investigated.”

Researchers examined the effect of camera use at Clearview Parkway and Veteran’s Memorial Boulevard, which State Farm insurance labeled as the ninth most dangerous intersection in the United States. The study did find that Redflex Traffic Systems, the Australian company in charge of the cameras, was able to issue fewer tickets after the installation period. From January through June 2008, however, tickets remained relatively steady at about 400 per month — enough to generate about $528,000 in annual revenue for the intersection.

“The steepest decline occurred during the initial four months of the study period,” the report found. “The mean number of citations stabilized and maintained this decrease when compared with the first half of the study.”

In the report’s brief treatment of safety statistics, researchers expressed surprise that the reductions in accidents promised by insurance industry studies failed to materialize.

“This study did not find a similar reduction in the total number of collisions,” the report stated. “This is perhaps due to the short-study period of only 10 months. Additional explanations include the absence of subset-analysis of different types of collisions, side- or front-end collisions compared with rear-end collisions. This study was designed to detect the difference in total collision episodes not the difference in types or injuries in collisions.”

Longer term, independent studies have found that red light cameras may even increase the number of accidents ( view studies). The Tulane researchers suggested that there are better alternatives to using cameras.

“Engineering counter measures have also been used to reduce red light running,” the study explained. “These include lengthening the yellow signal, dedicated turn signals and lanes, and reducing approach speeds to intersections.”

Jefferson Parish suspended its use of red light cameras earlier this year after documents revealed that Redflex paid 3.2 percent of the revenue from the camera program to lobbyist Bryan Wagner who shared the funds with the wife of District Judge Robert Murphy. The Redflex cut of the intersection above would be about $256,000. Assuming the other ten intersections in the parish would be at least as productive, Wagner was set to earn $90,000 a year from his cut of the photo tickets. Federal investigators are now looking into the matter.

    I go to New Orleans a lot since my daughter goes to Tulane and I usually stop at the Exxon station on the corner. Traffic is always heavy at the intersection since it's got one of the better shopping malls on the corner and during Mardi Gras so many parades start there. But if there were as many potholes on Veterans as their are in the neighborhoods in the Garden District everyone would be going so slow that accidents would be rare. Maybe since I'm only a visitor there I'm never in a big enough hurry to run a red light at the intersection. But the hardest thing to believe is that they only shoveled money to the wife of one judge. There is no way all those public officials there would only let one judge collect all the swag without forcing him to share the loot.

    1) What is Steven Seagal doing in Louisiana? 2) Why is he getting ready to draw his weapon?

      Despite his history of semi-associating with known mob types, he is sworn LEO. Has been for a long time. Really. Granted, the department has the same rep as New Orleans PD who works next door - let's just say they make Miami-Dade in the 80's look honest. Even more frightening, apparently the bottom of the reality show barrel has yet to be reached, as yes, that appears to be a capture from that 'show'.

  • TheMrFreeze That new Ferrari looks nice but other than that, nothing.And VW having to put an air-cooled Beetle in its display to try and make the ID.Buzz look cool makes this classic VW owner sad 😢
  • Wolfwagen Is it me or have auto shows just turned to meh? To me, there isn't much excitement anymore. it's like we have hit a second malaise era. Every new vehicle is some cookie-cutter CUV. No cutting-edge designs. No talk of any great powertrains, or technological achievements. It's sort of expected with the push to EVs but there is no news on that front either. No new battery tech, no new charging tech. Nothing.
  • CanadaCraig You can just imagine how quickly the tires are going to wear out on a 5,800 lbs AWD 2024 Dodge Charger.
  • Luke42 I tried FSD for a month in December 2022 on my Model Y and wasn’t impressed.The building-blocks were amazing but sum of the all of those amazing parts was about as useful as Honda Sensing in terms of reducing the driver’s workload.I have a list of fixes I need to see in Autopilot before I blow another $200 renting FSD. But I will try it for free for a month.I would love it if FSD v12 lived up to the hype and my mind were changed. But I have no reason to believe I might be wrong at this point, based on the reviews I’ve read so far. [shrug]. I’m sure I’ll have more to say about it once I get to test it.
  • FormerFF We bought three new and one used car last year, so we won't be visiting any showrooms this year unless a meteor hits one of them. Sorry to hear that Mini has terminated the manual transmission, a Mini could be a fun car to drive with a stick.It appears that 2025 is going to see a significant decrease in the number of models that can be had with a stick. The used car we bought is a Mk 7 GTI with a six speed manual, and my younger daughter and I are enjoying it quite a lot. We'll be hanging on to it for many years.
