Used By: This entry is used directly by one other data structure in this standard, a DF called
DF_PositionConfidenceSet <ASN> <XML>. In addition, this item may be used by data structures in
other ITS standards.
Remarks: Observe that the relationships between degrees of latitude or longitude and the distances given
are for the general area of North America. These values will, of course, change with the exact position of
the user on the face of the earth.
7.103 Data Element: DE_PreemptState
Use: The PreemptState data element is used to relate the current preemption state of a signal system.
Note that this data element follows the values and definitions of the preemptState object of NTCIP 1202
v2.19f as its starting point and adds values of 0 and 10.
ASN.1 Representation:
PreemptState ::= ENUMERATED {
none (0), -- No preemption (same as value = 2)
other (1), -- Other
notActive (2), -- Not Active (same as value = 0)
notActiveWithCall (3), -- Not Active With Call
entryStarted (4), -- Entry Started
trackService (5), -- Track Service
dwell (6), -- Dwell
linkActive (7), -- Link Active
existStarted (8), -- Exit Started
maximumPresence (9), -- Max Presence
ackowledgedButOverridden (10), -- Ackowledged but Over-ridden
... -- # LOCAL_CONTENT
}
-- To use 4 bits,
-- typically packed with other items in a BYTE
