This SAE standard specifies a message set, and its data frames and data elements, for use by applications that use vehicle-to-everything (V2X) communications systems. While the data dictionary was originally designed for use over DSRC, this document is intended to be independent of the underlying communications protocols used to exchange data between participants in V2X applications. This standard is the sixth edition of the message set dictionary. The changes made from prior editions are primarily related to creating modules of the ASN.1, separating the ASN.1 file into multiple modules that are organized by message and major topic. The ASN.1 files have been re-organized in a modular fashion for future expandability and growth. While recompiling with these new files is not necessary, it is highly recommended to maintain forward compatibility in the future. In addition, DE_TimeMark was modified to better support leap seconds; otherwise, there were no changes that affect backward compatibility. Also note that use of SSP indexes has been deprecated, but the fields remain in the ASN.1 definitions to support backward compatibility. Finally, definitions have been updated, descriptions of V2X communications have been generalized, and other minor editorial corrections were made.
