6.50 Data Frame: DF_VehicleComputedLane
Use: A VehicleComputedLane data structure provides lane number, lane width and lane attributes within
an approach structure for a drivable motorized vehicle lane. There is at least one ReferenceLane present
and may be zero or more ComputedLane objects as well in the enclosing Approach structure. Each
ComputedLane references a ReferenceLane found in the same intersection (using the index in which it is
found?) and an offset values to map the path of the lane.
ASN.1 Representation:
VehicleComputedLane ::= SEQUENCE {
laneNumber LaneNumber,
laneWidth LaneWidth OPTIONAL,
laneAttributes VehicleLaneAttributes,
refLaneNum LaneNumber,
-- number of the ref lane to be used
-- can reuse the lane number here
-- or for we need a new type
lineOffset DrivenLineOffset,
keepOutList NodeList,
-- no stop points along the path
...
}
