ORLANDO, Fla. -- The city of Orlando on Wednesday announced the seven intersections where cameras will be installed to help authorities catch red-light runners.

Orlando Mayor Buddy Dyer said the cameras are being installed in an attempt to make the intersections safer.

"We had 500 crashes that were the result of red-light running last year," Dyer said.

The cameras, which are scheduled to be installed and operating by Sept. 1, will be located at:

Conroy and Vineland roads

Turkey Lake and Wallace roads

Michigan Avenue and Dixie Belle Drive

Lee Vista Boulevard and South Goldenrod Road

Westmoreland Drive and South Street

West Kaley Avenue and South Division Avenue

North Magnolia Avenue and East Concord Street

The cameras will cost the city an estimated $1 million.

A driver running a red light will receive a $125 civil fine in the mail. If a camera catches a driver running a red light more than twice, the cost doubles to $250.

"The money that we collect from the program is going to be used to offset the expenses. If we have additional revenue, we are going to look into expanding the program," Mike Rhodes of Orlando Code Enforcement said.

Cameras were recently placed at three Orange County intersections.
