MassDOT has released several data feeds related to roadway traffic.

  • Real Time Travel Times

    MassDOT is providing Real Time Travel Times for roadways in Massachusetts.

  • Roadway Events

    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.

  • 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 are interested in gaining access to this API, please email our partners, TrafficLand - TrafficLand will respond and coordinate access to a unique API feed for your use.
