US: SAE Signal Preemption - LTE-V2X TCP

Description:

This solution is used within the U.S.. It combines standards associated with US: SAE Signal Preemption with those for V-X: LTE-V2X TCP. The US: SAE Signal Preemption standards include upper-layer standards required to implement signal preemption and priority information flows. The V-X: LTE-V2X TCP standards include lower-layer standards that support connection-oriented vehicle-to-any communications using the Transmission Control Protocol (TCP) over Internet Protocol version 6 (IPv6) over C-V2X in the 5.9GHz spectrum.

Solution Issues Severity: 18

The severity issue score calculation only includes issues associated with standards that are included by default.

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 Guidance document under development Standardization Gap This recommended practice on how to use the related standards is still under development but is not seen as strictly necessary to begin deployment of equipment.
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 Not a standard Standardization Gap The document may be publicly available but it is not currently available as a formal standard and details may change prior to adoption as a 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 Regulatory Permission Needed Standardization Gap Deployment of this standard requires regulatory approval, which is currently subject to significant delays.
True Medium Still under development Standardization Gap A draft of the standard has been developed by the working group, but it was still under development at the time this analysis was performed.
True Medium Uncertainty about trust revocation mechanism Security Gap The mechanisms used to prevent bad actors from sending authorized messages is unproven.
