This solution is used within the U.S.. It combines standards associated with US: ATIS with those for I–I: Secure Internet (ITS). The US: ATIS standards include upper–layer standards required to implement traveler information communications. The I–I: Secure Internet (ITS) standards include lower–layer standards that support secure communications between ITS equipment using X.509 or IEEE 1609.2 security certificates.

One serious or several significant issues. This category often includes proprietary or partial solutions. The communications solution may fail to provide even a base level of interoperability and security. Consider alternative solutions, or define specific revisions or upgrades that would provide a level of interoperability or security that are needed for the deployment.
