In 2006, Scottsdale installed speed enforcement cameras along its stretch of Loop 101 to combat the high fatality rate along its section of freeway. The photo enforcement was based on inductive sheeting on the freeway bed located at six fixed positions along the freeway - three in each direction. The photo enforcement was in a trial phase, with the trial ending in December 2006. In January 2007, the program was authorized by Arizona Governor Janet Napolitano to resume in February 2007.
