Scope
This SAE Document specifies DSRC interface requirements for V2V Safety Awareness applications, including detailed Systems Engineering documentation (needs and requirements mapped to appropriate message exchanges). These applications include: Emergency Vehicle Alert, Roadside Alert, and Safety Awareness Alerts for Objects and Adverse Road Conditions. This document extends the V2V Communications capabilities defined in J2945/1 to support these applications, and the National ITS Architecture.
The purpose of this SAE Document is to enable interoperability for V2V Safety Awareness communications.
Rationale
SAE J2945/2 provides a completed set of needs, requirements, and design for the four Use Cases within the scope of this standard, as well as traceability for each of these items.

Issuing Committee
V2X Vehicular Applications Technical Committee
V2X Vehicular Application (V2X VA) TC defines the V2X application and communication needs and requirements in the form of SAE international standards, recommended practices and/or technical reports for global adoption and reference. The focus is mainly from vehicle and mobile device perspective such as motor vehicles, motorcycles, pedestrians, cyclists and scooters, to address safety, mobility and other transportation needs. V2X VA TC also coordinates with other SDOs such as ISO and ETSI on related standards development.

* Redlines comparisons are available for those standards
listed in the Revision History that contain a radio button. A
redline comparison of the current version against a revision is
accomplished by selecting the radio button next to the standard and
then selecting 'compare'. At this time, Redline versions only exist
for some AMS standards. SAE will continue to add redline versioning
with ongoing updates to SAE MOBILUS.
