This is an SAE Motor Vehicle Council draft document of the DSRC committee, subject to change.
<xs:restriction base="xs:base64Binary">
<xs:length value="2"/>
</xs:restriction>
</xs:simpleType >
Used By: This entry is used directly by one other data structure in this standard, a DF called
DF_Intersection <ASN> <XML>. In addition, this item may be used by data structures in other ITS
standards.
Remarks: All zero indicates normal operating mode.
7.53 Data Element: DE_IntersectionID
Use: The IntersectionID is used to globally and uniquely define an intersection within a country or region
in a 32 bit field. Need some words about using the upper bytes with some common sense here.
ASN.1 Representation:
IntersectionID ::= OCTET STRING (SIZE(2..4))
-- note that often only the lower 16 bits of this value
-- will be send as the operational region (state etc) will
-- be known and not sent each time
XML Representation:
<xs:complexType name="IntersectionID" >
<xs:simpleContent>
<xs:annotation>

Used By: This entry is directly used by the following 3 other data structures in this standard (record type,
descriptive name, ASN.1, and XML name (if present) of each):
DF
<XML>, and
DF
<XML>, and
DF
In addition, this item may be used by data structures in other ITS standards.
Remarks: Values with the first three bytes set as zero are reserved for use as reference IntersectionIDs
(intersection which may be reused in other places by providing an ID and an anchor point to locate them).
