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.
