1. Scope
This SAE Standard specifies message sets, data frames and data elements 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 message sets,
data frames and data elements have been designed, to the extent possible, to also be of potential use for
applications that may be deployed in conjunction with other wireless communications technologies. This
standard therefore specifies representative 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.
1.1
Purpose
The purpose of this SAE Standard is to support interoperability among DSRC applications through the use
of standardized message sets, data frames and data elements. This Standard provides information that is
useful in understanding how to apply the various DSRC standards, along with the message sets, data frames
and data elements specified herein, to produce interoperable DSRC applications.
This second edition of the standard added addition content created since the first adopted edition and also
corrects minor typographical errors in found in the former edition.
