In addition, this item may be used by data structures in other ITS standards.
Remarks: Note: We reserve the upper bits for any other defined indications to be defined in the future,
such as enter a freeway or entering a private drive Treated as an octet byte when used in the packed octets
of the "Connects To" data frame (no BER tagging is present in this small blob).
7.72 Data Element: DE_LaneNumber
Use: The LaneNumber data element conveys a unique index value for a lane used to refer to that lane by
other objects in the intersection map data structure. Lanes may be ingress (inbound traffic) or egress
(outbound traffic) in nature, as well as barriers and other types of specialty lanes. All lanes are numbered.
The LaneNumber, in conjunction with the intersection ID, forms a regionally unique way to address a
specific lane in that intersection.

LaneNumber ::= OCTET STRING (SIZE(1))
