The concept for Vehicle to Infrastructure (V2I) applications supporting safety, mobility and the environment has as its foundation underlying enabling technology, standards, and policies.  
The concept involves research towards implementation…
The development and deployment of a fully connected transportation system that makes the most of multi-modal, transformational applications requires a robust, underlying technological platform. The platform is a combination of well-defined technologies, interfaces, and processes that, combined, ensure safe, stable, interoperable, reliable system operations that minimize risk and maximize opportunities.
Connected vehicle research has been organized into the following focus areas:
Connected Vehicle Technology
Connected Vehicle Applications
Connected Vehicle Technology Policy and Institutional Issues

This presentation is focused on the Infrastructure part of the Connected Vehicle Program.

Within the ITS/JPO Connected Vehicle Program, there are three areas devoted to application development:  Safety, Mobility and the Environment.  Development of the various suites of applications are being conducted under separate efforts, yet many of the proposed applications require data from infrastructure. 
V2I Communications is the system-wide effort directed to allow infrastructure components to participate in the Connected Vehicle environment, regardless of the purpose of that participation.  It is a cross-cutting effort that is described by a Vision to “Transform surface transportation safety, mobility, and environmental performance through a connected vehicle environment.”
The mission of V2I Communications is two-fold: to develop the requirements for transfer of information between vehicles and infrastructure, and to establish guidance to assist public agencies in making investment decisions related to deployment  of V2I infrastructure.

The V2I Communications for Safety research program is comprised of three tracks that define the work program. 
Track 1, Enabling Technologies – will culminate in the V2I Reference Implementation, which will include the standards, specifications and interfaces for hardware and firmware that can be used in the connected vehicle environment. The V2I Reference Implementation will also include a physical manifestation, a complete system of the hardware and firmware that can be used to evaluate potential applications and be used to insure new systems are compatible and interoperable with other components.  
Track 2, Application Selection, Development and Evaluation – builds on crash analysis work to select V2I Safety applications that have potential to significantly reduce the cost of traffic crashes.  Work has progressed through defining Systems Requirements for three priority safety applications (red light violation warning, stop sign gap assistance, and curve speed warning).  On-going work includes development of Systems Requirements for an additional set of potential applications, including rail-grade crossing warnings, vehicle restrictions (height/weight), speed management (e.g.: school zones and work zones), Stop Sign Violation, and work zone warnings (including alignment changes and active/inactive notifications).
Track 3, Infrastructure Planning and Policy – includes various efforts to establish governance and business models for V2I Communications.  The AASHTO “footprint” study is part of this track.  Systems analyses are being conducted to determine what components and capabilities are the absolute minimum required if an agency desires to support safety, mobility, data capture, and environmental applications.  Work under this track will incorporate the standards and specifications produced under Track 1, and the CBAs for various applications developed under Track 2, to assist agencies in making deployment and investment decisions.  The final product of this track are Public Agency Guidelines and Specifications, which are intended to help decision makers identify the total costs of participating in the connected vehicle environment, including potential liability and regulatory issues, and also define the anticipated benefits, including improved safety, reduced congestion, performance/asset management issues, and environmental impacts.

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.
