City Hall’s long standing defense of red light cameras for safety’s sake is under attack from a first of its kind scientific study.
Now, some are saying they could be doing more harm than good.
The study commissioned by the Tribune finds the cameras don’t reduce accidents as much as advertised and actually increase some kinds of wrecks.
Mayor Emanuel has quoted statistics saying the cameras reduced T-bone accidents by 47 percent.
But the study found such broadside collisions that caused injuries were down only 15 percent at intersections monitored by cameras.
On the other hand, those intersections saw an increase in rear end collisions with injuries of 22 percent.
Traffic experts say the study shows the cameras should be reevaluated.
With more than 200 cameras, Chicago’s is the largest program in the nation.
Drivers have paid more than $500 million in fines since 2005.
