Roadway Events
This is a feed of current incident data from the Highway Division. It includes incidents that may affect travel or traffic conditions on roadways. It does not include all incidents in Massachusetts.
For information on current and planned work zone events across Massachusetts, the MassDOT Connected Work Zone (CWZ) standard should be consumed.
MassDOT Connected Work Zone (CWZ) Standard
This dataset provides up‑to‑date information on current and planned work zone events across Massachusetts in the Connected Work Zones (CWZ) format. CWZ is an industry‑ and community‑designed standard, based on the Work Zone Data Exchange (WZDx) specification, that supports consistent, machine‑readable delivery of real‑time work zone data to connected vehicles, navigation platforms, and developer applications. To access the Connected Work Zones (CWZ) feed, developers must create a free account in the MassDOT Work Zones API portal and generate an API key to authenticate requests.
Traffic Cameras
MassDOT Shares access to its traffic cameras with developers and third-parties via an API providing live JPEG imagery at the rate of 1 frame per 120 seconds. If you would like access to this API, please email our partners, TrafficLand. TrafficLand will respond and coordinate access to a unique API feed for your use.
