This document is not a standard, it is a candidate for a standard being submitted to SAE for their consideration as a comment to SAE J2735. The term SAE J2735 SE candidate is used within this document to refer to this submission.
This document specifies dialogs, messages, and the data frames and data elements that make up the messages specifically for use by applications intended to utilize the 5.9 GHz Dedicated Short Range Communications for Wireless Access in Vehicular Environments (DSRC/WAVE, referenced in this document simply as “DSRC"), communications systems. Although the scope of this Standard is focused on DSRC, these dialogs, messages, data frames and data elements have been designed, to the extent possible, to be of use for applications that may be deployed in conjunction with other wireless communications technologies. This standard therefore specifies the definitive message structure and provides sufficient background information to allow readers to properly interpret the message definitions from the point of view of an application developer implementing the messages according to the DSRC Standards.
The SAE DSRC Technical Committee (TC) has received this recommendation for a comprehensive revision of SAE J2735, including documentation of the Systems Engineering (SE) process that is the foundation for the suggested normative content found herein. The committee is publishing this recommendation in this non-normative information report (IR) in the interest of exposing the recommendation to a large number of stakeholders. This IR does not replace the SAE J2735 standard.
The TC is considering this recommendation along with other suggested revisions. Any revision of SAE J2735 will be produced by the DSRC TC using normal SAE procedures. The committee takes no position at this time with regard to the content of the recommendations. Some material in this recommendation might eventually be reflected in other technical reports produced by the DSRC TC, including SAE standard J2735, while other material might not. The recommendation is written in the form of a standard, and includes language that suggests normative requirements and options. In the context of this information report, however, these statements are intended purely for information to the reader about the recommendation, and not as normative statements from SAE.
While some of the information in this document can aid in understanding or implementing a test deployment of DSRC, the committee recommends that the document not be used to form implementation requirements. The current published revisions in SAE J2735 remain normative and shall take precedence over any conflicting portions of this document.
There is no conformance statement for this information report. The DSRC TC welcomes comments about this recommendation, as well as suggestions related to all DSRC standards within the scope of this committee.
