Regional Transportation Advisory Council

Home » About Us

The Regional Transportation Advisory Council is an independent body that brings public viewpoints and advice on transportation planning to the Boston Region Metropolitan Planning Organization (MPO). Membership includes municipalities, professional organizations, transportation advocacy groups, and state agencies. Anyone is welcome to attend and participate in Advisory Council meetings.


The Advisory Council’s monthly meetings offer a forum for broad-based and robust discussions of transportation issues. The Advisory Council is a voting member of the MPO board and is one of several avenues for public participation in the MPO’s planning process.

The Advisory Council typically meets on the second Wednesday of each month at 2:30 PM, virtually, on Zoom. All meetings are open to the public. Please visit the MPO's calendar for meeting links, agendas, minutes, presentations, and other meeting-related materials.
