Drivers adapt to red-light cameras

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.

What we are doing is making people paranoid — causing them to slam on the brakes at the slightest hint a light might change, or deciding to fail to make even an absolutely safe right turn on red

This is an interesting addition to a link I posted from 2008.

In fact, six U.S. cities have been found guilty of shortening the yellow light cycles below what is allowed by law on intersections equipped with cameras meant to catch red-light runners.
