Used By: This entry is directly used by the following 2 other data structures in this standard (record type,
descriptive name, ASN.1, and XML name (if present) of each):
DF
<XML>, and
MSG
In addition, this item may be used by data structures in other ITS standards.
6.2 Data Frame: DF_AccelSteerYawRateConfidence
Use: A single byte long data frame combining multiple related bit fields into one byte.
ASN.1 Representation:
AccelSteerYawRateConfidence ::= SEQUENCE {
yawRate YawRateConfidence,
-- 3 bits
acceleration AccelerationConfidence,
-- 3 bits
steeringWheelAngle SteeringWheelAngleConfidence
-- 2 bits
}
XML Representation:
<xs:complexType name="AccelSteerYawRateConfidence" >
<xs:sequence>
<xs:element name="yawRate" type="YawRateConfidence" />
<!-- 3 bits -->
<xs:element name="acceleration" type="AccelerationConfidence" />
<!-- 3 bits -->
<xs:element name="steeringWheelAngle" type="SteeringWheelAngleConfidence" />
<!-- 2 bits -->
</xs:sequence>
</xs:complexType>
Used By: This entry is used directly by one other data structure in this standard, a DF called
DF_ConfidenceSet <ASN> <XML>. In addition, this item may be used by data structures in other
ITS standards.
6.3 Data Frame: DF_Approach
Use: The Approach data structure is used to bundle related motor vehicle lanes (both reference lanes and
computed lanes are described) within the intersection for an Approach or Egress description which is part
of an intersection. It also allows expressing information about any barriers found between lanes
(medians), other types of lanes (such as a train crossings), and information about pedestrian and bicycle
lanes or walkways, all of which may cross the described motor vehicle lanes (at arbitrary angles).
ASN.1 Representation:
