This is an SAE Motor Vehicle Council draft document of the DSRC committee, subject to change.

</xs:simpleType>
Used By: This entry is used directly by one other data structure in this standard, a DF called
DF_VehicleSize <ASN> <XML>. In addition, this item may be used by data structures in other ITS
standards.
7.150 Data Element: DE_VehicleMass
Use: The mass of the vehicle. With an LSB of 25 kg, this produces a max range of 6375kg (14,025 lbs).
Mass should reflect current gross mass of vehicle and contents if known, otherwise an average laden value
should be established. If cases where the mass is greater then 6375 Kg then the value of 255 shall be used.
ASN.1 Representation:
VehicleMass ::= INTEGER (0..255) -- mass with an LSB of 25 Kg
XML Representation:
<xs:simpleType name="VehicleMass" >

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
MSG
In addition, this item may be used by data structures in other ITS standards.
Remarks: [Note: There is debate in the Traffic Info group to change the value range used here to allow up
to 40 tons. The normal privacy and tracking concerns apply. ]
7.151 Data Element: DE_VehicleRequestStatus
Use: The VehicleRequestStatus data element is used to relate status information about a vehicle when
requesting service from a signalized intersection. It relates some basic information about the requester
which can be used by the signal systems in its response with changes to the timing plan in use. Note that
this status is used in both priority and preemption use cases but that the information mapped into the lower
4 bits varies with each.
ASN.1 Representation:
VehicleRequestStatus ::= OCTET STRING (SIZE(1))
-- With bits set as follows:
-- Bit 7 (MSB) Brakes-on, see notes for use
-- Bit 6 Emergency Use or operation
-- Bit 5 Lights in use (see also the light bar element)
-- Bits 5~0
-- when a priority, map the values of
-- LightbarInUse to the lower 4 bits
-- and set the 5th bit to zero
-- when a preemption, map the values of
-- TransistStatus to the lower 5 bits
