Transportation Improvement Program (TIP)

Home » Our Work

The Transportation Improvement Program (TIP) is the five-year rolling capital plan for the 97 cities and towns in the Boston Region Metropolitan Planning Organization's (MPO) planning area. The TIP documents all transportation projects that will receive federal funding in the region over the next five years. Projects in the TIP include those supported by Regional Target funds—the federal transportation dollars that the MPO has direct discretion over—and federally funded projects of the Massachusetts Department of Transportation (MassDOT), the Massachusetts Bay Transportation Authority (MBTA), the MetroWest Regional Transit Authority (MWRTA), and the Cape Ann Transportation Authority (CATA).

TIP Project Cost Policies

In the spring of 2021, the MPO board voted to create an Ad Hoc Committee to explore the ongoing issue of cost increases for programmed TIP projects. The goal of the committee was to explore the causes and consequences of cost increases for projects that the MPO funds and recommend possible policy changes to the full MPO board. The committee was chaired by the MPO board’s vice chair, representing the Metropolitan Area Planning Council, and had eight members representing MassDOT, the Regional Transportation Advisory Council, the MBTA Advisory Board, the City of Boston, the City of Everett, the City of Somerville, the Town of Medway, and the Town of Rockland.

The committee met six times, ultimately voting to recommend a set of policies to the full MPO board. This fact sheet (PDF) fact sheet (HTML) outlines proposed policy changes to the TIP process. This proposal is available in a more detailed format in a memo (PDF) memo (HTML) submitted to the MPO board for consideration at the board’s meeting on Thursday, September 23, 2021. At that meeting, the board voted to release this proposal for public review. The public comment period closed at 5:00 PM on Monday, October 18, 2021. The committee met on October 21, 2021, to review public comments. The MPO voted to endorse the new policies at its meeting on November 4, 2021. The MPO applied the new policies for the first time during the development of the FFYs 2023–27 TIP, which was endorsed by the MPO on May 26, 2022.

Past Meetings

Federal Reporting

The MPO must publish a complete list of obligated projects within 90 days after the close of the FFY. Obligated projects are projects that have funds committed to them through the approval of a construction contract. The list includes the amount of money approved in the TIP, the total amount obligated, and the remaining balance for each project or program. The FFY 2023 Federal Obligation Report (PDF) lists the MassDOT, MBTA, CATA, and MWRTA projects within the MPO area that spent federal funds during FFY 2022 (October 1, 2022–September 30, 2023). Federal obligation reports from previous FFYs may be found in the TIP Archive.

Older TIP documents and the lists of projects that were advertised for construction in prior years are available in the archive.
