The Massachusetts Department of Transportation could raise MBTA fares by five percent next year.

State officials announced Tuesday a plan to buy new Red Line and Orange Line Subway cars, reconfigure part of the Mass. Turnpike in Allston, and establish electronic tolling on existing roads.

On Wednesday, Transportation Secretary Richard Davey said the plans wouldn’t stop there:

“More to come. Certainly Tuesday was our very first discussion. I think in the very near future we’ll be talking about some other projects outside the Boston region,” Davey told the State House News Service.

“No scenario” exists, Davey said, where new subway cars won’t need to be purchased.

MBTA officials are reportedly already in talks with stakeholders and plan to have informal discussions with commuters in the coming months. By November, the MBTA could develop two scenarios that would see fares increase by July 2014, T officials told the Transportation Board Wednesday.

Fares were raised 23 percent in July of 2012.

MBTA GM Beverly Scott is reportedly meeting with youth, seniors and the disabled to discuss the impact of potential fare hikes.

With $340 million in new taxes available through the Massachusetts Department of Transportation, the MBTA is allowed to raise fares no more than 5 percent every two years, according to MBTA officials.

Transportation officials are reportedly looking to “potentially” encourage biking and walking in all projects.
