-

This is an SAE Motor Vehicle Council draft document of the DSRC committee, subject to change.
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):
MSG
<XML>, and
MSG
In addition, this item may be used by data structures in other ITS standards.
Remarks: This item is no longer used in edition two of the standard. Use the VehicleStatusDeviceTypeTag
instead.
6.37 Data Frame: DF_VehicleSize
Use: The VehicleSize is a data frame representing the vehicle length and vehicle width in a three byte
value.
ASN.1 Representation:
VehicleSize ::= SEQUENCE {
width VehicleWidth,
length VehicleLength
} -- 3 bytes in length
XML Representation:
<xs:complexType name="VehicleSize" >
<xs:annotation>
<xs:documentation>
3 bytes in length
</xs:documentation>
</xs:annotation>
<xs:sequence>
<xs:element name="width" type="VehicleWidth" />
<xs:element name="length" type="VehicleLength" />
</xs:sequence>
</xs:complexType>

6.38 Data Frame: DF_VehicleStatusDeviceType
Use: A data frame that is used to relate specific items of the vehicles status. This structure relates all the
different types of information that can be related about the vehicle inside a probe message. Typically these
are used in data event snapshots which are gathered and periodically reported to an RSU.
Observe that this data structure makes use of other defined data elements and data frames, enclosing them
in a choice structure so that one (and only one) such item can be sent within the VehicleStatusDeviceType
instance but that this data follows the definition of each defined elsewhere.
ASN.1 Representation:
VehicleStatusDeviceType ::= CHOICE {
lights ExteriorLights, -- Exterior Lights
wipers SEQUENCE {
status WiperStatus,
rate WiperRate
}, -- Wipers
brakes SEQUENCE {
status BrakeSystemStatus,
