US: SAE Other J2735 - LTE-V2X TCP
Description:
This solution is used within Canada and the U.S.. It combines standards associated with US: SAE Other J2735 with those for V-X: LTE-V2X TCP. The US: SAE Other J2735 standards include upper-layer standards required to implement V2X information flows that do not yet have fully specified functionality and performance charcateristics. 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.Relevant Regions:
- Canada
- United States
Comm Profile: V-X: LTE-V2X TCP
Comm Class: LAN - Local Area Network

Solution Issues Severity: 14
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 | Overlap of standards (Minor) | 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. However, as this information transfer is infrastructure-based, agencies can deploy a solution throughout their jurisdiction with minimal downside and can use gateways to connect to other technologies. |
| True | Low | Time synchronization | Performance / Applicability Gap | The standard requires a highly accurate time shared between participants. |
| True | Medium | Uncertainty about trust revocation mechanism | Security Gap | The mechanisms used to prevent bad actors from sending authorized messages is unproven. |
| True | High | Application specification not defined | ITS Info Gap | The logic, performance, and application security rules are not defined for this information flow. |
