-
203 -
This is an SAE Motor Vehicle Council draft document of the DSRC committee, subject to change.
<xs:documentation>
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

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
MSG
In addition, this item may be used by data structures in other ITS standards.
Remarks: The MSB bit (the brakes-on bit) is used in the general sense of a vehicle which is not moving or
proceeding towards to light. Examples of use would be a response vehicle that has stopped short of the
light, but more typically a transit vehicle making a stop to load/unload before reaching the light. This bit
can be used by the signal system to disregard a request.
7.152 Data Element: DE_VehicleStatusDeviceTypeTag
Use: The VehicleStatusDeviceTypeTag element is an enumeration of every possible value which can be
found in the VehicleStatusDeviceType data frame. It is used to denote that value (and hence also the
length) of the data which follows it.
ASN.1 Representation:
