ET Meeting Slides


	This diagram illustrates how the three V2I tracks fit together.

	Track 1, Enabling Technologies – the enabling technology interacts with work to develop all V2I applications, including Safety, Mobility, and the Environment. Some of the components of the V2I Reference Implementation include an updated Signal Phase and Timing (SPaT) message set with map and GPS correction signal. Other potential firmware changes in a connected vehicle controller are signal logic revisions that allow for a more interactive, adaptive signal control that provides mobility and environmental benefits along with information for vehicle-based safety applications.
	Track 2, Application Selection, Development and Evaluation – Over the next two years, four or five V2I Safety applications will be developed and field tested. Formal cost:benefit analyses (CBAs) will result in defining safety effectiveness data.
	Track 3, Infrastructure Planning and Policy – Each agency will make independent decisions regarding whether or not to invest in V2I systems, the extent of any such deployment, and the manner in which investment and deployments are made. There may or may not be business models that support public-private partnerships, or that stimulate industry support for data capture and management. US DOT cannot define how V2I deployment will occur, but the intent is to have a system of standards and specifications that permit participation in the connected vehicle environment, within defined parameters and using appropriate protocols to preserve the integrity of the data and communications between entities. The standards and specifications are also intended to be robust enough to insure that systems remain backward and forward compatibility over an extended period of time, to protect investments in infrastructure and vehicles.
