Used By: This entry is used directly by one other data structure in this standard, a DF called
DF_ApproachesObject <ASN> <XML>. In addition, this item may be used by data structures in other
ITS standards.
Remarks: Note that the integer value given to each described item (lane, barrier, crosswalk, etc.) is used
in other messages and data frames to refer to that object within the context of the globally unique
intersection that this data frame is used in.
6.4 Data Frame: DF_ApproachesObject
Use: The ApproachesObject data structure associates a set of related approaches and egresses with each
