In addition, this item may be used by data structures in other ITS standards.
6.53 Data Frame: DF_VehicleReferenceLane
Use: A VehicleReferenceLane data structure provides lane number, lane width and lane attributes within
an approach structure for a drivable lane for motor vehicles. There is typically at least one ReferenceLane
present for each approach and may be zero or more VehicleComputedLane objects, barrier objects, and
crosswalk objects as well in the enclosing approach structure. The nodeList provide a detailed set of offset
values to map the path and width of the lane.
ASN.1 Representation:
VehicleReferenceLane ::= SEQUENCE {
laneNumber LaneNumber,
laneWidth LaneWidth OPTIONAL,
laneAttributes VehicleLaneAttributes,
nodeList NodeList,
-- path details of the lane and width
keepOutList NodeList OPTIONAL,
-- no stop points along the path
