8.17 Data Frame: DF_ITIS-Codes_And_Text [ITIS]
Use: The use of ITIS codes interspersed with free text. The complete set of ITIS codes can be found in
Volume Two of the J2540 Standard. This is a set of nealry 1,500 items which are used to encode common
events and list items in ITS.
ASN.1 Representation:
ITIScodesAndText ::= SEQUENCE (SIZE(1..100)) OF SEQUENCE {
item CHOICE {
itis ITIScodes,
text ITIStext
} -- # UNTAGGED
}
XML Representation:
<xs:complexType name="ITIScodesAndText" >
<xs:sequence minOccurs="1" maxOccurs="100">
<xs:choice >
<xs:element name="itis" type="ITIScodes" />
<xs:element name="text" type="ITIStext" />
</xs:choice>
</xs:sequence>
</xs:complexType>
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.
Remarks: Refer to the SAE ITIS entry ITIScodes for the complete (and lengthy) listing of these codes and
for an XML rendering.
8.18 Data Element: ESS_EssMobileFriction [NTCIP]
Use: Indicates measured coefficient of friction in percent. The value 101 shall indicate an error condition
or missing value.
ASN.1 Representation:
EssMobileFriction ::= INTEGER (0..101)
XML Representation:
<xs:simpleType name="EssMobileFriction" >
<xs:restriction base="xs:unsignedByte">
<xs:maxInclusive value="101"/>
</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.
8.19 Data Element: ESS_EssPrecipRate_quantity [NTCIP]
Use: The rainfall, or water equivalent of snow, rate in tenths of grams per square meter per second (for
rain, this is approximately to 0.36 mm/hr). A value of 65535 shall indicate an error condition or missing
value.
ASN.1 Representation:
EssPrecipRate ::= INTEGER (0..65535)
XML Representation:
<xs:simpleType name="EssPrecipRate" >
<xs:restriction base="xs:unsignedShort"/>
</xs:simpleType>
