US: SAE Basic Safety Messages -  WAVE WSMP
Description:
This solution is used within Canada and the U.S..  It combines standards associated with US: SAE Basic Safety Messages with those for V-X: WAVE WSMP. The US: SAE Basic Safety Messages standards include upper-layer standards required to implement V2V safety 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.
Comm Profile: V-X: WAVE WSMP
 
Standards in Profile:
| Level | Doc # | Standard | Description | 
|---|
| Access |  | Bundle: WAVE - Subnet | A bundle of standards specifying the lower layers of the reference communications model for the US DSRC environment. | 
| Security |  | Bundle: IEEE 1609.2 | A bundle of standards that groups a set of IEEE security standards together for easy reference. | 
| TransNet | IEEE 1609.3 | IEEE 1609.3 WAVE - Networking Services | This standard defines the network and transport layer options for the WAVE environment. The standard defines three options: a bandwidth efficient single-hop solution known as WSMP, UDP/IP, and TCP/IP. It has been harmonized with ISO FNTP and FSAP - a common message format specified in ISO 16460. | 
Data Profile: US: SAE Basic Safety Messages
 
Standards in Profile:
| Level | Doc # | Standard | Description | 
|---|
| Facilities | SAE J2735 | SAE J2735 DSRC Message Set | This standard defines the data and messages for use in DSRC (i.e., V2V, V2I, and V2D) applications. The SAE J2945 series defines additional requirements on how to use these messages. | 
| Facilities | SAE J2945 | SAE J2945/0 DSRC Common Design Elements | This standard defines cross-cutting material which applies to the J2945/x series including generic DSRC interface requirements and guidance on Systems Engineering (SE) content. | 
| ITS Application Entity | SAE J2735 | SAE J2735 DSRC Message Set | This standard defines the data and messages for use in DSRC (i.e., V2V, V2I, and V2D) applications. The SAE J2945 series defines additional requirements on how to use these messages. | 
| ITS Application Entity | SAE J2945/1 | SAE J2945/1 V2V Basic Safety | This standard specifies the system requirements for an on-board vehicle-to-vehicle (V2V) safety communications system for light vehicles, including standards profiles, functional requirements, and performance requirements. | 
Readiness Description: 
One serious or several significant issues. This category often includes proprietary or partial solutions.  The communications solution may fail to provide even a base level of interoperability and security.  Consider alternative solutions, or define specific revisions or upgrades that would provide a level of interoperability or security that are needed for the deployment.
