Release 2.2 of the Research Data Exchange and New Connected Vehicle Data Sets Are Now Available

The Research Data Exchange (RDE) is a web-based data resource provided by the USDOT Intelligent Transportation Systems (ITS) Program.  It collects, manages, and provides access to archived and real-time multi-source and multi-modal data to support the development and testing of ITS applications.

New Data Environments Added to the RDE

The RDE now contains two new data environments associated with intersection queues and weather sensing applications which were demonstrated during the 2014 ITS World Congress in Detroit, MI and which are available for download:

  • Intersection Queueing data and Situation data based on J2735 messages:
    • Queue counts by lane at a downtown intersection
    • Counts of instrumented vehicles in queue at traffic signal phases
    • Videos of queues
    • Vehicle situation data from nine instrumented vehicles
    • Intersection and traveler situation data from Roadside Units
  • Data from a Weather Sensing and Alert Demonstration
    • Road weather-related observation data
    • Road weather-related advisory warnings.

New Features for Release 2.2

  • Version control to track updated versions of data.
  • A link to the Weather Data Environment (WxDE) containing road weather data
  • A graphical and text based search capability across all data environments
  • The ability to “like” or promote files with social media

Researchers, application developers, and others are invited to visit the RDE website at to explore how they may use the available data and resources. For more information about the RDE, please contact Gene McHale at or Jon Obenberger at
