Used By: This entry is used directly by one other data structure in this standard, a DF called
DF_SignalRequest <ASN> <XML>. In addition, this item may be used by data structures in other ITS
standards.
7.24 Data Element: DE_CoefficientOfFriction
Use: Coefficient of Friction of an object, typical a wheel in contact with the ground. This DE is typically
used in sets where the value of each wheel is provided in turn as a measure of relative local traction.
ASN.1 Representation:
CoefficientOfFriction ::= INTEGER (0..50) -- re-confirm this range
-- where 0 = 0.00 micro (frictonless)
-- and 50 = 0.98 micro, in steps of 0.02
XML Representation:

Used By: This entry is used directly by one other data structure in this standard, a DF called
DF_VehicleStatus <ASN> <XML>. In addition, this item may be used by data structures in other ITS
standards.
Remarks: [Note: I seem to recall the ESS people defined some of this for mobile field devices, we should
compare with them and see what we can re-use.]
7.25 Data Element: DE_Collision Event Flag (remove now, use event flags)
Use: A data element used to denote the type of probable event relating to a possible Intersection Collision.
ASN.1 Representation:
CollisionEventFlag ::= ENUMERATED {
unknown (0),
intersectionViolation (1), -- Need other values from committte here
itemThree (2),
itemFour (3)
}
