This is an SAE Motor Vehicle Council draft document of the DSRC committee, subject to change.
7.42 Data Element: DE_SirenInUse
Use: A data element which is set if any sort of audible alarm is being emitted from the vehicle. This includes
various common sirens as well as backup up beepers and other slow speed maneuvering alerts.
Used to reflect any type or style of audio alerting when a vehicle is progressing and transmitting DSRC messages
to others about its path. Intended to be used as part of the DSRC safety message for public safety vehicles
operating in the area.

SirenInUse ::= ENUMERATED {
notEquipped (0),
notInUse (1),

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.
7.43 Data Element: DE_SpeedConfidence
Use: This DE is used to provide to listeners the confidence interval of the 95% confidence level for the currently
reported value of DE_Speed, taking into account the current calibration and precision of the sensor(s) used to
measure and/or calculate the value. This data element is only to provide the listener with information on the
limitations of the sensing system; not to support any type of automatic error correction or to imply a guaranteed
maximum error. This data element should not be used for fault detection or diagnosis, but if a vehicle is able to
detect a fault, the confidence interval should be increased accordingly.
The frame of references and axis of rotation used shall be accordance with that defined in SAE J670, Issued 1976-
