The North Carolina Agricultural & Technical State University did an RLC study in 2004 that revealed some flaws in the arguments being used for the implementation of Red Light Cameras.  The study demonstrated the opposite result of that which camera supporters claim:

"However, the intersections where RLCs were installed are not experiencing the same decrease. When analyzing total crashes, we find that RLCs have a statistically significant (p<0.001) and large (40% increase) effect on accident rates.  

In addition, RLCs have a statistically significant, positive impact on rear-end accidents, sideswipes, and accidents involving cars turning left (traveling on the same roadway).  

The one type of accident found to experience a decrease at RLC sites are those involving a left turning car and a car traveling on a different roadway. "
