Data Notes: Due to the lack of more comprehensive bus stop accessibility data, this metric relies on bus stop inventory data from the system-wide survey that was conducted as a part of MBTA's Plan for Accessible Transit Infrastructure (PATI) program. As such, it only reflects the current accessibility status of surveyed stops at the time and does not account for all current stops. The program classified stops as Critical, High, Medium, Low priority or Compliant, based on the severity and number of accessibility barriers. For this metric, "substantially accessible" refers to stops without Critical or High priority barriers. This metric excludes Silver Line stations, which are instead covered under the Station Accessibility metric.

Data Notes: Data contain only MBTA stations at this time.

Data Notes: This metric considers the portion of all non-commercial trips starting and ending in Massachusetts that were made by walking, biking/micromobility, public transit, or carpooling.

Data Notes: These metrics consider the time elapsed between the issuance of a learner's permit and the issuance of a license, including driver education, any re-tests due to failing on the first attempt, etc.

Data Notes: For this metric, Electric is based on the Zero Emissions category of the MA Vehicle Census, which includes battery & fuel cell electric vehicles and plug-in hybrid electric vehicles, but does not include conventional hybrid electric vehicles.

Data Notes: Calculated using the MassDOT Bike Inventory year-end file. Data is current as of the end of the previous calendar year, and includes both state-owned infrastructure as well as facilities under local jurisdiction. This metric captures shared use paths, bike lanes, separated bike lanes, and bicycle/pedestrian priority roadways.
