More photo radar cameras are on tap for the city of Phoenix.

Officer William Fisher said the additional cameras will target more than just red-light runners.

Fisher said there currently are red-light cameras at 12 intersections and two vans which do speed enforcement around schools and school zones.

"They're talking about maybe adding some intersections -- maybe speed on green or mid-block speed and maybe some enforcement around the light rail," said Fisher.

He said cameras also will be used for secondary infractions, like expired tags, cracked windshields and seatbelt violations.

The cameras will be installed later this summer.

The exact locations have not been decided, according to Fisher.

"Usually how they pick the intersection is by statistics, by red-light running tickets or collisions in that intersection," he said.
