Study: Red Light Cameras Don't Improve Safety
An anonymous reader writes: Ars Technica summaries a study by the Chicago Tribune (paywalled) that found red light cameras do not improve driver safety. "[W]hile right angle crash incidents have been reduced, rear-end crashes that resulted in injuries went up 22 percent." Chicago officials recently claimed that the cameras led to a 47% reduction "T-bone" injury crashes, using that statistic as evidence that the program is worthwhile. But the study's authors, who "accounted for declining accident rates in recent years as well as other confounding factors, found cameras reduced right-angle crashes that caused injuries by just 15 percent."
They also noted that the city chose to install many cameras at intersections where crashes were rare to begin with. Chicago has raised roughly $500 million from red light camera tickets since 2002. "[O]fficials recently admitted to the city inspector general that they had quietly dropped the threshold for what constitutes a red light camera ticket, allowing the tickets even when cameras showed a yellow light time just under the three-second federal minimum standard. That shift earlier this year snared 77,000 more drivers and $7.7 million in ticket revenue before the city agreed to change the threshold back.

It was always about the revenue, safety was a smokescreen swallowed by the gullible
On the flipside, 80% of the people arguing against them really just want to be able to run red lights with impunity.
