<xs:restriction base="xs:unsignedByte">
<xs:maxInclusive value="50"/>
</xs:restriction>
</xs:simpleType>
Used By: This entry is used directly by one other data structure in this standard, a DF called
DF_VehicleStatus <ASN> <XML>. In addition, this item may be used by data structures in other ITS
standards.
Remarks: [Note: I seem to recall the ESS people defined some of this for mobile field devices, we should
compare with them and see what we can re-use.]
7.26 Data Element: DE_Collision Event Flag (remove now, use event flags)
Use: A data element used to denote the type of probable event relating to a possible Intersection Collision.
ASN.1 Representation:
CollisionEventFlag ::= ENUMERATED {
unknown (0),
intersectionViolation (1), -- Need other values from committte here
itemThree (2),
itemFour (3)
}
XML Representation:
<xs:simpleType name="CollisionEventFlag" >
<xs:annotation>
<xs:appinfo>
unknown (0)
intersectionViolation (1) -- Need other values from committte here
itemThree (2)
itemFour (3)
</xs:appinfo>
</xs:annotation>

<xs:simpleType>
<xs:restriction base="xs:unsignedInt">
<xs:minInclusive value="0"/>
<xs:maxInclusive value="3"/>
</xs:restriction>
</xs:simpleType>
<xs:simpleType>
<xs:restriction base="xs:string">
<xs:enumeration value="unknown"/>
<xs:enumeration value="intersectionViolation"/>
<xs:enumeration value="itemThree"/>
<xs:enumeration value="itemFour"/>
</xs:restriction>
</xs:simpleType >
</xs:union>
</xs:simpleType>
In addition, this item may be used by data structures in other ITS standards.
Remarks: Note: Is this item now overcome by the event flag item (the one that relates to passing the stop
line), can we remove it and use that? Need to confirm with safety sub-committee first but is seems likely.
7.27 Data Element: DE_ColorState
Use: An enumerated state representing what the color and flashing state of a signal light is (regardless of
any directional indication or arrow that may also be associated with that light). Typically used in an array
to represent signal lights.
