Cobb is hoping to make money by selling advertising on its CCT buses and outdoor terminals.

On Tuesday the commission authorized transportation officials to issue a request for proposals advertisers. The bus system has raised fairs and cut routes recently to save money and increase revenue.

Cobb is spending up to $362,794 on a marketing study for CCT expected to be completed later this fall. Potential advertising revenue is estimated between $50,000 and $100,000 for fiscal 2012, and between $225,000 and $330,000 for fiscal 2013.
