Dedicated Short Range Communication (DSRC) Systems Engineering Process Guidance for SAE J2945/X Documents and Common Design Concepts™
- Ground Vehicle Standard
Published December 07, 2017 by SAE International in United States
This SAE Standard serves as the guidance document for the J2945/x family of standards as illustrated in Figure 7. It contains cross-cutting material which applies to the other J2945/x standards, including recommended practice for the use of Systems Engineering (SE) and generic DSRC interface requirements content.
The scope for the DSRC system environment is to provide for the information exchange between a host vehicle and another DSRC enabled device, a device worn by or otherwise attached to a traveler, a roadside device, or a management center, to address safety, mobility, and environmental system needs.
The audience for this document includes the technical teams of developers of the J2945/x documents and the implementers of the applications which are based on the J2945/x documents.
This is an "interim progress release" which provides a snapshot of in-work content. It is intended to provide an opportunity for TC input and guidance, and to support overall coordination among the set of standards currently in development.
Please note that this document is intended to be cross cutting, and should serve the goal of stating a great many common aspects of DSRC that the DSRC TC often takes for granted. New developers will need this information. While it is a normative document for some common aspects of DSRC, it also provides informative material on both the exchanged messages, on DSRC systems, and many aspects of ITS work that together form a complex system.
This standard is dedicated to the memory of Peter Byk, who provided support and guidance in the evolution of the DSRC standards. He fostered the collaborative effort among SAE International, Federal and State governments, and the ITS industry that enabled a team of stakeholders and subject matter experts to create the DSRC message standards which will improve transportation safety and mobility.

* 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.
