US: SAE Lane-Level Mapping - WAVE WSMP

Description:

This solution is used within Canada and the U.S.. It combines standards associated with US: SAE Lane-Level Mapping with those for V-X: WAVE WSMP. The US: SAE Lane-Level Mapping standards include upper-layer standards required to implement lane-level and road furniture mapping 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

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.

Level	Doc #	Standard	Description
Facilities	SAE J2945	SAE J2945 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.
Facilities	SAE J2945/A	SAE J2945/A Road Geometry	The document provides a generalized mapping solution that can be applied to future infrastructure-based application standards using a layering approach, so that each new application standard at most needs to define a new layer of information that is unique to specific V2X application. It provides an ability to describe small, lane-level map descriptions that apply directly to V2X applications such as reduced speed zones (e.g. work zones) and curves (e.g. curve speed warning).
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/A	SAE J2945/A Road Geometry	The document provides a generalized mapping solution that can be applied to future infrastructure-based application standards using a layering approach, so that each new application standard at most needs to define a new layer of information that is unique to specific V2X application. It provides an ability to describe small, lane-level map descriptions that apply directly to V2X applications such as reduced speed zones (e.g. work zones) and curves (e.g. curve speed warning).
Security		ITS Security Alternatives	A set of alternative standards that provides the three major options for signing and encrypting messages within the ITS environment.

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.
