US: SAE Safety Awareness Messages - WAVE WSMP

Description:

This solution is used within Canada and the U.S.. It combines standards associated with US: SAE Safety Awareness Messages with those for V-X: WAVE WSMP. The US: SAE Safety Awareness Messages standards include upper-layer standards required to implement V2V safety situation awareness information flows. 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.

Solution Issues Severity: 24

Solution Issues:

Default	Severity	Name	Type	Description
True	Low	Data not defined in standard format	ITS Info Gap	The definition of data concepts should conform to ISO 14817-1 to promote reuse among ITS.
True	Low	Not a standard (minor)	Standardization Gap	The document is publicly available and widely used but it is not currently a formal standard.
True	Medium	Overlap of standards	Overlap	Multiple standards have been developed to address this information and it is unclear which standard should be used to address this specific information flow.
True	Medium	Uncertainty about trust revocation mechanism	Security Gap	The mechanisms used to prevent bad actors from sending authorized messages is unproven.
True	High	Draft not available (Critical)	Standardization Gap	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.
True	High	Regulatory Issue	Standardization Gap	Deployment of this standard is subject to regulatory approval, which is not currently expected to be granted for deployments in the near-term.
