Track 3 will provide the critical technology underpinnings that allow V2I applications to be deployed nationally and across jurisdictional lines.

The outcome of Track 3 will be a foundation for V2I that includes communications, SPaT, mapping, positioning, and security, to enable multiple systems or components to exchange useful data and information. The final product is an Integrated V2I Infrastructure System that will serve as the reference implementation for the infrastructure component of V2I.
