Connected Vehicle Standards are rules that provide the software programming codes, definitions, and formats needed to create interoperable, consistent, and seamless communications exchange among shared information systems and devices. To accelerate the deployment and adoption of connected vehicle systems, preclude redundancy, and reduce costs and complexity, the US DOT seeks to harmonize ITS standards. This process involves stakeholders, including vehicle and equipment manufacturers, standards organizations, and governments, working together to agree on harmonized standards across multiple regions.

The vision for the ITS Standards program is to enable interoperable connected vehicle and ITS services within a complex, multimodal, connected transportation network, including both vehicles and infrastructure. To do so, the ITS Standards Program is participating in and facilitating the development of standards and protocols that establish the rules for how ITS (and, specifically, connected vehicle) devices, vehicles, and operations centers communicate and exchange information with one another. The program is also partnering with NHTSA and other interested modal administrations, to participate in international standards harmonization activities.
