Program to Support the Development and Deployment of Infrastructure Based Connected Vehicle Applications
A connected vehicles environment holds the potential to support a fundamental advance in surface transportation. While the vehicle component and infrastructure component of the transportation system have traditionally been only loosely coupled (through static signing, vehicle presence detectors, etc.), connected vehicle technology will allow the components to “work” actively together – creating a fully connected vehicles and infrastructure environment. This provides the potential for reduction in congestion, safety improvements, and improved traveler services. In order to realize this potential, a connected vehicles system and environment will require unprecedented collaboration between the private and public sectors, on a scale not required in the current loosely coupled system.
To date, the federal USDOT Connected Vehicle initiative has focused largely on “how” to technically accomplish the integration. A considerable amount of solid technical work has been devoted to developing communications standard (e.g., Dedicated Short Range Communications (DSRC)), developing and deploying field equipment for small-scale prototype/proof-of-concept testing, and high-level conceptual development. As this work has progressed, it has become increasingly clear that there will not be a single way to implement connected vehicle technologies. For example, recent activities in the national program have demonstrated that aftermarket equipment and wireless technologies in addition to DSRC should be considered when exploring deployment of connected vehicles applications.
As owners and operators of the nation’s surface transportation infrastructure, state and local transportation agencies are at the core of the connected vehicle infrastructure. While automakers and device manufacturers will dictate availability of vehicular equipment, transportation agencies will control the deployment and operation of roadside infrastructure and the incorporation of connected vehicle technologies into infrastructure applications (such as traffic signal control). To guide transportation agency involvement in connected vehicle deployments, AASHTO developed a Strategic Plan and Field Infrastructure Footprint Analysis to aid the owners and operators in the nationwide deployment of the connected vehicle infrastructure. It also identified the need for infrastructure providers to conduct research to develop applications that will make full use of the connected vehicle environment.
With this background, the pooled fund study entitled “Program to Support the Development and Deployment of Connected Vehicle Applications” was created by a group of state, local, and international transportation agencies and Federal Highway Administration (FHWA) in order to provide a means to conduct the work necessary for infrastructure providers to play a leading role in advancing the Connected Vehicle systems. Participating agencies include California Department of Transportation (DOT), Colorado DOT, Connecticut DOT, Delaware DOT, FHWA, Florida DOT, Georgia DOT, Maricopa County DOT in Arizona, Maryland DOT, Michigan DOT, Minnesota DOT, New Jersey DOT, New York DOT, Ohio DOT, Pennsylvania DOT, Tennessee DOT, Texas DOT, Transport Canada, Utah DOT, Washington DOT, and Wisconsin DOT with the Virginia DOT as lead agency and the University of Virginia Center for Transportation Studies as technical leadership provider.
