City Removes Red Light Cameras But Keeps Speed Camera Program

El Mirage, Arizona will no longer enforce red-light running with cameras but will keep speed cameras active.  Was it because of a cost or maintenance issue?  Or was it because only 10% of the tickets were coming from red-light runners?

Will this be a growing trend as drivers become more aware of these intersections and the locations become unprofitable.  Red-light cameras decrease in value to the city over time as people become more aware of the locations.  However, speed cameras and right turn cameras seem to be the new hot trend for cities to make more money.
