Red Light Cameras Raise Crash Risk, Cost

concealment writes with news of dissatisfaction with a pilot program for stoplight-monitoring cameras. The program ran for several years in New Jersey, and according to a new report, the number of car crashes actually increased while the cameras were present. "[The program] appears to be changing drivers’ behavior, state officials said Monday, noting an overall decline in traffic citations and right-angle crashes. The Department of Transportation also said, however, that rear-end crashes have risen by 20 percent and total crashes are up by 0.9 percent at intersections where cameras have operated for at least a year. The agency recommended the program stay in place, calling for 'continued data collection and monitoring' of camera-monitored intersections. The department’s report drew immediate criticism from Assemblyman Declan O’Scanlon, R-Monmouth, who wants the cameras removed. He called the program 'a dismal failure,' saying DOT statistics show the net costs of accidents had climbed by more than $1 million at intersections with cameras." Other cities are considering dumping the monitoring tech as well, citing similar cost and efficacy issues.

Is it still a win in your books when the cities shorten the yellow to generate more tickets?

Red light cameras increase both crashes and safety

That isn't surprising. The Federal Highway Administration found that red-light cameras increase rear-end collisions but reduce more severe right-angle collisions, saving $50,000 in collisions per intersection per year in medical and repair costs. [dot.gov]

Assemblyman Declan O'Scanlon, R-Monmouth..wants the cameras removed.

That would be an extremely bad idea. "In the immediately aftermath of the [red light camera] law's expiration, the risk of someone running a red light at an intersection was three times higher than it had been when cameras were on." [theatlanticcities.com]

If safety is the goal, they should keep the red light cameras and lengthen the yellow light duration. "An Institute study conducted in Philadelphia, Pennsylvania, evaluated effects on red light running of first lengthening yellow signal timing by about a second and then introducing red light cameras. While the longer yellow reduced red light violations by 36 percent, adding camera enforcement further cut red light running by another 96 percent." [iihs.org]

If you rear end someone you are by definition following too close and the accident is your fault. That means that if you get rear ended the person you should be suing is the one that dented your ride.
At least that is the law where I live (not in the US)

You must have skipped over #1 and #2.

Hard to tell without access to the raw figures, but if the number of T-bone crashes has reduced, replaced by more rear-end incidents, is it possible that the injury rate, or at least number of serous injuries or fatalities, has decreased? Even if the net cost in car damage increases, that would still be a win in my books.

Then why don't you look at the raw data instead of pure conjecture? And no, you are wrong.

Pay attention to tables 4, 5, and 6.

Yes, it's sounds like the real problem here is that these areas of the US are suffering from a major tailgating problem above all else.

All a red light camera does is catches people who run a red light. I was always taught that when approaching traffic lights, approach them as if they're going to change and that's exactly what they do. I've never had a problem stopping for a red light, not once and neither have I had anyone go into the back of me at traffic lights.

From the comments on this thread it sounds like people in the US race up to lights and then slam their brakes on and everyone behind them tailgates as that's the only reason red light cameras would increase crash risk and cost. If that's the case then it sounds like there's a more fundamental issue here - that driving test standards in the US simply aren't high enough, and policing of bad driving isn't done well enough.

Maybe the US does need more raised roundabouts, you have little choice but to slow down coming up to them, otherwise you crash right into them and have to explain to the cops how the fuck you managed to land your car in the middle of a roundabout. That way people who drive like idiots automatically get caught because with a bit of shrubbery on the roundabout too it makes it hard for them to get away from the scene, assuming their car is even in good enough state to do so still. They soon learn.
