This is an SAE Motor Vehicle Council draft document of the DSRC committee, subject to change.
7.133 Data Element: DE_TractionControlState
Use: The status of the vehicle traction system. The "Traction Control Status" Probe Data Element is
intended to inform Probe Data Users whether one or more of the vehicle's drive wheels was slipping during
an acceleration at the time the Probe Data snapshot was taken. The element informs the user if the vehicle
is NOT equipped with a traction control system. If the vehicle is equipped with a traction control system,
the element reports whether the system is in an Off, On or Engaged state.
ASN.1 Representation:
TractionControlState ::= ENUMERATED {
notEquipped (0), -- B'00 Not Equipped
off (1), -- B'01 Off
on (2), -- B'10 On
engaged (3) -- B'11 Engaged
}
-- Encoded as a 2 bit value

7.134 Data Element: DE_TransistStatus
Use: The TransitStatus data element is used to relate basic information about the transit run in progress.
This is typically used in a priority request to a signalized system and becomes part of the input processing
for how that system will respond to the request.
ASN.1 Representation:
TransitStatus ::= BIT STRING {
none (0), -- nothing is active
anADAuse (1), -- an ADA access is in progress (wheelchairs, kneling, etc.)
aBikeLoad (2), -- loading of a bicyle is in progress
doorOpen (3), -- a vehcile door is open for passenger access
