7.6 Data Element: DE_ApproachNumber
Use: The ApproachNumber data concept coveys a unique index value for an approach or an egress in an
intersection for the convenience of human users. It is typically used along with an optional human readable
string name for the object. Note the ApproachNumber is not used in numbering the lanes, refer to the
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_ATIS-AdvisoryNumber
Use: AAA An empty definition field.
ASN.1 Representation:
ATISAdvisoryNumber ::= INTEGER (0..65535)
XML Representation:
<xs:simpleType name="ATISAdvisoryNumber" >
<xs:restriction base="xs:unsignedShort"/>
</xs:simpleType>
Used By: This entry is used directly by one other data structure in this standard, a DF called
MSG_TravelerInformation <ASN> <XML>. In addition, this item may be used by data structures in
other ITS standards.
7.8 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.
ASN.1 Representation:
