  • RDE Feedback RDE Feedback

    As part of the RDE Release 2.2 we are soliciting feedback from current and potential users of ITS and Connected Vehicle data. We realize the importance of gauging end-user satisfaction since the RDE is the CDS Program's primary interface to the broader transportation research community. We need your input to help us make the RDE a more user-friendly and impactful resource within the research community! Please login or create a new account to provide feedback.

  • Buses and cars communicating with each other and roadside equipmen Connected Vehicle Research

    The US DOT ITS program is researching connected vehicle technologies and applications. Our vision is one of pervasive real time data that connects vehicles, transportation infrastructure, and mobile devices to enable applications that improve transportation safety, mobility, and the environment. For more information on the US DOT connected vehicle research program, please visit US DOT ITS Joint Program Office .

The Research Data Exchange (RDE) is developed as a transportation data sharing system that promotes sharing of both archived and real-time data from multiple sources (including vehicle probes) and multiple modes. This new data sharing capability will better support the needs of ITS researchers and developers while reducing costs and encouraging innovation.

The primary purpose of the Connected Data Systems (CDS) Research Data Exchange is to provide a variety of data-related services that support the development, testing, and demonstration of multi-modal transportation mobility applications being pursued under the USDOT ITS Dynamic Mobility Applications (DMA) Program and other connected vehicle research activities. Data accessible through the Research Data Exchange will be well-documented and freely available to the public. The vision of the CDS Program is to enhance current operational practices and transform future transportation systems management through the active acquisition and systematic provision of integrated data from infrastructure, vehicles, and travelers. This data is available to researchers, application developers, and others.
