4.4 SAE DSRC standards
SAEJ2735 Dedicated Short Range Communications (DSRC) Message Set Dictionary comprises a set of messages, data frames, and data elements intended for both vehicle-to-vehicle (V2V) and vehicle- to-infrastructure (the roadside) (V2IZ) safety exchanges. It includes specifications of each message, as well as explanatory usage text required to properly understand and implement that message. Informative annexes explain the operational concepts of several of the safety applications.
SAE is developing a family of standards, which includes guidance for the use of systems
engineering (SE) and generic DSRC interface niluirements content. The parent document is SAE

4.5.1 General
As of this writing, the terminology used in ITS related standards is relatively new, and usage of terms has not yet stabilized. In conjuncon with the efforts to harmonize IEEE 1609 standards with those of ISO (sdficallv Iso 21217 [B51] and related standards and technical spifications). there is an on going effort in building consensus regarding how terminolo should be used and how terms should he defined. The following provides some historical context and information helpM to understanding suhsu en I detailed discussions rarding terminology usage.
4.5.2 Historical perspective
In IEEE Std i6O9.gTM2p13 [B24], some changes were made to the terminology used to define and describe the PSID and its use in layers above the transport layer. Terms such as “applicafion -service were introduced, with the objective to be more flexible in describing what occurs above the WSMP protocol. These changes eventually made their way into the most recently published IEEE Std l6O9.3TM2016 [B31] and IEEE Std 1609. 121M2016 [B35] versions.
Additionally. international standards groups introduced terminology to describe the ITS station architecture. For example. terms such as service, applition object. application class, application. application process. and numerous other terms are ddined in ISO standards. In some cases, the terminology used in these standards does not exactly align with terminology used in IEEE 1609 standards. The inconsistencies in terminology usage in the aforementioned IEEE and international standards, which have significant overlap, has been a source of confusion to many.
Other standards organizations (e.g., SAE) and various programs that use standards have introduced new terminology into their lexicons. For example the ARC-IT reference architecture uses some terminology that is uniciue to that project (see Annex H).
