This is an SAE Motor Vehicle Council draft document of the DSRC committee, subject to change.
LaneNumber data element and the ApproachesObject data structure for a description of how indexing
works.
ASN.1 Representation:
ApproachNumber ::= INTEGER (0..127)
XML Representation:
<xs:simpleType name="ApproachNumber" >
<xs:restriction base="xs:unsignedByte">
<xs:maxInclusive value="127"/>
</xs:restriction>
</xs:simpleType>
Used By: This entry is used directly by one other data structure in this standard, a DF called
DF_Approach <ASN> <XML>. In addition, this item may be used by data structures in other ITS
standards.
7.7 Data Element: DE_BarrierAttributes
Use: The BarrierAttributes data element relates the type of barrier being described. A barrier in this
context is any described lane style of object which normal vehicle traffic can or can-not transverse.
