MassDOT has released several BETA .xml feeds related to roadway traffic.
I-93 Travel Times
MassDOT is conducting a trial test on Interstate 93 (I-93) from the New Hampshire border to Canton to gather real-time travel times. Read the documentation below for information about the XML feed formats.
MassDOT has released a BETA .xml feed of planned roadway events. This feed does not include all roadwork in Massachusetts, but it does include many of the construction, maintenance, and other events undertaken by the MassDOT Highway Division that may affect travel or traffic conditions on Massachusetts roadways. This is a BETA feed -- please send us suggestions for improvements.

MassDOT's bicycle data layer includes facilities at all stages of development from envisioned resources through constructed lanes and paths. The layer contains a unique identifier for each bike facility links to the Road Inventory, and multiple name fields from overlapping naming schemes. Multiple subsets of bike data are incorporated in this one layer. Some key terms are listed below:
The Bay State Greenway is a proposed 775-mile statewide network of on- and off-road bicycle facilities traversing Massachusetts along seven connected corridors. Some of its segments have already been constructed.
Existing facilities include bike lanes, cycle tracks, and marked routes on roads, in addition to shared use off-road paths and unpaved trails.
Facilities in feasibility study, design, or construction phases have funding that is promised, programmed, or being disbursed for the given phase.
Proposed and envisioned facilities cover projects that have been proposed in regional or municipal long-range plans or are being actively promoted by advocating entities.
We have two versions of this data, KML and Shape versions, available on this page. Both files contain the data layer as well as a data dictionary and a usage guide.
