US: SAE VRU Messages - Local Unicast Wireless (1609.2)

Description:

This solution is used within the U.S.. It combines standards associated with US: SAE VRU Messages with those for V-X: Local Unicast Wireless (1609.2). The US: SAE VRU Messages standards include upper-layer standards required to implement vulnerable road user information flows. The V-X: Local Unicast Wireless (1609.2) standards include lower-layer standards that support local-area unicast wireless solutions applicable to North America, such as WAVE DSRC, LTE-V2X, LTE, Wi-Fi, etc.

Relevant Regions:

• United States

Solution Issues Severity: 4

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	Medium	Uncertainty about trust revocation mechanism	Security Gap	The mechanisms used to prevent bad actors from sending authorized messages is unproven.
False	Low	Relatively new technology	Standardization Gap	The standard is finalized but has not been widely deployed. Deployment experience may result in further revisions in the technology, although it is expected that the standards group will make reasonable efforts to make any changes backwards compatible.
False	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.
False	Medium	Regulatory Permission Needed	Standardization Gap	Deployment of this standard requires regulatory approval, which is currently subject to significant delays.
False	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.
