  • Abstract:
    The United States Department of Transportation (USDOT) is engaged in assessing applications that realize the full potential of connected vehicles, travelers, and

    infrastructure to enhance current operational practices and transform future surface transportation systems management. This effort, known as the Connected Vehicle

    Program, is a collaborative initiative spanning the Intelligent Transportation Systems Joint Program Office (ITS JPO), Federal Highway Administration (FHWA), Federal

    Transit Administration (FTA), Federal Motor Carrier Safety Administration (FMCSA), Federal Railroad Administration (FRA) and National Highway Traffic Safety

    Administration (NHTSA). At its foundation is a communications network that supports vehicle-to-vehicle (V2V), vehicle-to-infrastructure (V2I), vehicle-to-pedestrian (V2P), and

    vehicle or infrastructure-to-device (X2D) communications. Onboard equipment (OBE) units consist of connected vehicle equipment installed in the vehicle capable of

    broadcasting and receiving wireless messages. Roadside units (RSU) consist of roadside equipment capable of broadcasting and receiving wireless messages from


    With its unique operational behaviors, vehicle characteristics, institutional assets, and mission to serve the public, the transit community holds a unique set of opportunities to

    support V2I applications that benefit all road users in general, and transit riders in particular.

    The overall scope of this Transit Connected Vehicle V2I Assessment Study is to: (i) to perform a thorough cross-cutting exploration of transit unique V2I needs (such as data

    and communications needs), opportunities (where transit can contribute, for example, to the data environments) and constraints (such as ownership of and accessibility to

    certain infrastructures), and then (ii) define and prioritize selected transit V2I application bundles, and develop operational descriptions. This report, as a final project report,

    documents the thought process and approaches used in this study, as well as key findings derived from these research activities.
