9.3 Message: MSG_ProbeDataManagement
Use: Taken at a defined snapshot event to define RSU coverage patterns such as the moment an OBU joins
or becomes associated with an RSU and can send probe data.
ASN.1 Representation:
ProbeDataManagement ::= SEQUENCE {
msgID DSRCmsgID, -- This is a unique message
-- identifier, NOT related to
-- the PSID\PSC
sample Sample, -- identifies vehicle
-- population affected
directions HeadingSlice,

term CHOICE {
termtime TermTime, -- Terminate management process
-- based on Time-to-Live
termDistance TermDistance -- Terminate management process
-- based on Distance-to-Live
},
snapshot CHOICE {
snapshotTime SnapshotTime, -- Collect snapshots based on time
snapshotDistance SnapshotDistance -- Collect snapshots based on Distance
},
txInterval TxTime, -- Time Interval at which to send snapshots
cntTthreshold INTEGER (1..32), -- number of thresholds that will be changed
dataElements SEQUENCE (SIZE(1..32)) OF
-- a data frame and its assoc thresholds
