US: SAE Platooning - WAVE TCP
Description
This solution is used within the U.S.. It combines standards associated with US: SAE Platooning with those for V–X: WAVE TCP. The US: SAE Platooning standards include upper–layer standards required to manage platooning and cooperative adaptive cruise control. The V–X: WAVE TCP standards include lower–layer standards that support connection–oriented vehicle–to–any communications within ~300m using the Transmission Control Protocol (TCP) over Internet Protocol version 6 (IPv6) over IEEE WAVE in the 5.9GHz spectrum.

Readiness: Moderate–Low
Readiness Description
Multiple significant and 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. Some solutions in this category may also be becoming obsolete from an interoperability perspective and if this is the case, then upgrades should be planned as soon as possible. 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.
Issues
| Issue | Severity | Description | Associated Standard | Associated Triple |
|---|
| Draft not available (Critical) | High | The standards development organization has established a work item for the subject standard but a draft is not available for this critical feature to enable the interface. The draft may be missing due to the work item being new or simply a lack of activity on the work item. | SAE J2945/6 CACC and Platoon | (All) |
|---|
| Data not defined in standard format | Low | The definition of data concepts should conform to ISO 14817–1 to promote reuse among ITS. | SAE J2735 DSRC Message Set | (All) |
