US: SAE Platooning - WAVE WSMP

Description

This solution is used within the U.S.. It combines standards associated with US: SAE Platooning with those for V–X: WAVE WSMP. The US: SAE Platooning standards include upper–layer standards required to manage platooning and cooperative adaptive cruise control. The V–X: WAVE WSMP standards include lower–layer standards that support connectionless, near constant, ultra–low latency vehicle–to–any communications within ~300m using the WAVE Short Messaging Protocol (WSMP) over IEEE WAVE in the 5.9GHz spectrum. The broadcast mode is interoperable with M5 FNTP.

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.
