This is an SAE Motor Vehicle Council draft document of the DSRC committee, subject to change.
7.33 Data Element: DE_DOffset
Use: The DSRC style (time zone) offset is a simple value consisting of a signed integer representing an
hour and minute value set from -14:00 to +14:00 representing all the worlds local time zones in units of
minutes.  The value of zero (00:00) may represent an unknown value.  Note some time zones are do not
align to hourly boundaries.
ASN.1 Representation:
DOffset ::= INTEGER (-340..340) -- units of minutes from UTC time
XML Representation:
<xs:simpleType name="DOffset" >
      <xs:annotation>
         <xs:documentation>       
            units of minutes from UTC time
         </xs:documentation>
      </xs:annotation>
      <xs:restriction base="xs:short">
         <xs:minInclusive value="-340"/>
         <xs:maxInclusive value="340"/>
      </xs:restriction>
</xs:simpleType>
In addition, this item may be used by data structures in other ITS standards.
7.34 Data Element: DE_DrivenLineOffset
Use: The DrivenLineOffset is an integer value expressing the perpendicular offset from a reference lane
number that a computed lane is offset from.  The measurement is taken from the reference lane center line
to the new center line, independent of any width values.  The units are a signed value with an LSB of 1 cm.  
ASN.1 Representation:
DrivenLineOffset ::= INTEGER (-32767..32767) 
   -- LSB units are 1 cm.
XML Representation:
<xs:simpleType name="DrivenLineOffset" >
      <xs:annotation>
         <xs:documentation>       
            LSB units are 1 cm.
         </xs:documentation>
      </xs:annotation>
      <xs:restriction base="xs:short">
         <xs:minInclusive value="-32767"/>
      </xs:restriction>
</xs:simpleType>
Used By: This entry is used directly by one other data structure in this standard, a DF called
DF_VehicleComputedLane <ASN> <XML>.   In addition, this item may be used by data structures in
other ITS standards.
7.35 Data Element: DE_DrivingWheelAngle
Use: The angle of the front (steering) wheel, expressed in a signed (to the right being positive) value with
units of 0.3333 degrees and a range of plus or minus 42.33 degrees.  The value of zero shall be when both
wheels are pointed such as to drive the vehicle in a straight ahead direction (the tow-in angle of each side
being equal and canceling each other out).  A value of zero shall be sent when unknown.
ASN.1 Representation:
DrivingWheelAngle ::= INTEGER (-127..127) 
   -- LSB units of 0.3333 degrees. 
   -- a range of 42.33 degrees each way
