Did you read the article?

The reason for the divergence of opinions is a statistical problem, 
according to critics, study authors and city officials.
The analysis examined crash data at intersections that had a camera 
monitoring at least one of the four or more traffic signals in an 
intersection. Most intersections had a camera installed in only one 
direction, meaning that there were three other signals at that intersection 
without cameras.

Interestingly, it was those unmonitored points in the intersection that saw 
the greatest increase in accidents. Where there is a camera, the accidents 
remained relatively flat or showed only a slight increase.

"Collisions are going up all over the city," said Bob Stein, a Rice 
University political science professor and one of the report's authors. "But 
red-light cameras have held back that increase at approaches where they have 
been installed."
