Ben Franklin Transit's 2012 budget was passed unanimously Thursday night by the transit board.

The $30.2 million budget maintains routes and services.

The budget as written also does not propose raising fares, but transit officials said that might be considered in 2012.

The proposed $30.2 million 2012 budget is a 4.5 percent increase over this year's $28.9 million budget, and includes $29 million in spending and leaves $1.2 million in reserves.

Next year's budget projects the transit system will receive $23.4 million in sales tax money with only $4.7 million coming from fares and $2.4 million from state and federal sources.

The budget also freezes wages for most transit workers. Only mechanics under a union contract would get a 2.5 percent increase, and some workers who have been with the transit system less than five to six years might qualify for merit raises, but no cost-of-living increases are budgeted.
