This is an SAE Motor Vehicle Council draft document of the DSRC committee, subject to change.
1. SCOPE
This SAE Recommended Practice is intended as a guide toward standard practice and is subject to change to
keep pace with experience and technical advances. This SAE Recommended Practice specifies standard
message sets, data frames and data elements 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. The scope is limited to specifying initial representative
message structure and providing sufficient background information to allow readers to properly interpret the DSRC
standards and message definitions from the point of view of an application developer.
1.1
Purpose
The purpose of this SAE Recommended Practice is to support interoperability among DSRC applications through
the use of standardized message sets, data frames and data elements. This Recommended Practice 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.
