The United States Department of Transportation's (USDOT) Intelligent Transportation Systems (ITS) program is developing an intelligent vehicle communications system to enable vehicle-to-vehicle communications and communications between vehicles and roadside infrastructure, remote users, or remote service providers. This system will enable development of an array of applications aimed at improving safety and mobility while also enabling a variety of additional commercial applications by automotive original equipment manufacturers (OEM) and other commercial service providers. This system-the Vehicle Infrastructure Integration (VII) System-is being developed as a coordinated effort among public and private sector partners. The VII System is a visionary initiative with a primary goal to improve public safety, mobility, and commerce on U.S. roadways. It will achieve these benefits through an increased flow of information among vehicles, their operators, roadside infrastructure (signal controllers, sensors, etc.), and third parties with access to the VII information network. The program is being developed jointly by the USDOT, the automobile manufacturing industry, the American Association of State Highway Transportation Officials, and a number of state Departments of Transportation. The VII initiative will develop a large-scale high-speed data communications network overlaid with a service-oriented architecture (SOA) based foundation of systems providing advanced telematics services. It will incorporate Dedicated Short Range Communications (DSRC) in the licensed 5.9 gigahertz (GHz) band based on the IEEE 1609 wireless standard specifically designed for vehicular use in conjunction with the IEEE 802.11p wireless local area network (WLAN) protocol. Thevision of the VII architecture is that every car manufactured in the United States would be equipped with on-board equipment (OBE) consisting of a communications device, a positioning device, a processing platform, and application software located within the vehicle. The OBE would exchange datawith roadside equipment (RSE), which would be deployed along major highways and at signalized intersections in metropolitan areas throughout the United States. The OBE would also communicate with other OBEs for vehicle-to-vehicle data exchange. A nationwide communications network would link RSEs with remote network users to support the data flow among these users andvehicles. For the covering abstract see ITRD E134653.
