This solution is used within the U.S.. It combines standards associated with US: SAE J3067 (J2735 SE) with those for I–I: Guaranteed Secure Internet (ITS). The US: SAE J3067 (J2735 SE) standards include a proposed solution for the upper–layers to implement V2X information flows that do not yet have fully standardized messages, functionality or performance characteristics. The I–I: Guaranteed Secure Internet (ITS) standards include lower–layer standards that support secure communications with guaranteed delivery between ITS equipment using X.509 or IEEE 1609.2 security certificates.

| ITS Application Entity | SAE J3067 | Candidate Improvements to Dedicated Short Range Communications (DSRC) Message Set Dictionary [SAE J2735] Using Systems Engineering Methods | This informational report formalized a deliverable received from the USDOT as suggested improvements to SAE J2735:2009. Many of these suggestions have been incorporated into later revisions of SAE J2735 and SAE J2945/x; additional suggestions may be incorporated as the documents are extended to address additional applications. |

Two significant or one significant and several minor issues. For existing deployments, the chosen solution is likely deficient in security or management capabilities and the issues should be reviewed and upgrades developed as needed. For new deployments, the solution may be viable for pilots when applied to the triples it supports; such pilot deployments should consider a path to addressing these issues as a part of their design activities. The solution does not provide sufficient interoperability, management, and security to enable proper, full–scale deployment without additional work.
