DRAFT SAE J2735 DEDICATED SHORT RANGE
COMMUNICATIONS (DSRC) MESSAGE SET DICTIONARY
Forward
This 2nd edition of the standard provides additional DSRC messages developed beyond
those defined in the first edition and incorporating feedback from early deployment
experience. A uniform method of message encoding, using ASN.1 DER encoding,
replaces the implicit binary encoding developed in the first edition, although some binary
encoding remains in selected messages for efficiency. The messages defined in this
edition have been designed to support deployment in such a way as to remain compatible
with additional further planned message content, still in development at this time.
Prepared for use by the DSRC committee of the SAE by SubCarrier Systems Corp ( SCSC ).
