ABC6 reports that the stop-light cameras on the south side of City Hall caught the most violators last year, issuing more than 22,000 tickets.
Philadelphia currently has red light cameras at 25 intersections and will be adding them next at Stenton and Oregon avenues, as well as at Island and Bartram.
The other question AAA looked at, is it cost-effective? Their analysis revealed the city handed out $17.7 million in fines last year, and made $9.5 million on that, which goes to PennDOT.
AAA has concluded the system actually promotes traffic safety in Philadelphia.
