This is an SAE Motor Vehicle Council draft document of the DSRC committee, subject to change.
XML Representation:
<xs:complexType name="DTime" >
<xs:sequence>
<xs:element name="hour" type="DHour" />
<!-- 1 byte -->
<xs:element name="minute" type="DMinute" />
<!-- 1 byte -->
<xs:element name="second" type="DSecond" />
<!-- 2 bytes -->
</xs:sequence>
</xs:complexType>
In addition, this item may be used by data structures in other ITS standards.
6.19 Data Frame: DF_DYearMonth
Use: The DSRC style year-month is a compound value consisting of finite-length sequences of integers
(not characters) of the form: "yyyy, mm" - as defined below. Because the length of each element is
known, no inner element tagging is normally used in transmission. Thus, this data frame occupies 3 bytes
in total.
ASN.1 Representation:
DYearMonth ::= SEQUENCE {
year DYear, -- 2 bytes
month DMonth -- 1 byte
}
XML Representation:
<xs:complexType name="DYearMonth" >
<xs:sequence>
<xs:element name="year" type="DYear" />
<!-- 2 bytes -->
<xs:element name="month" type="DMonth" />
<!-- 1 byte -->
</xs:sequence>
</xs:complexType>
In addition, this item may be used by data structures in other ITS standards.
6.20 Data Frame: DF_FullPositionVector
Use: A complete report of the vehicle's position, speed, and heading. Used in the probe vehicle message
as the initial position information (followed by shorter frames).
ASN.1 Representation:
FullPositionVector ::= SEQUENCE {
utcTime DDateTime OPTIONAL, -- time with mSec precision
long Longitude, -- 1/8th microdegree
lat Latitude, -- 1/8th microdegree
elevation Elevation OPTIONAL, -- 3 bytes, 0.1 m
heading Heading OPTIONAL,
speed Speed OPTIONAL,
timeConfidence TimeConfidence OPTIONAL,
posConfidence PositionConfidenceSet OPTIONAL,
speedConfidence SpeedandHeadingConfidence OPTIONAL,
... -- # LOCAL_CONTENT
}
XML Representation:
<xs:complexType name="FullPositionVector" >
<xs:sequence>
<xs:element name="utcTime" type="DDateTime" minOccurs="0"/>
<!-- time with mSec precision -->
<xs:element name="long" type="Longitude" />
