leftBoundary

R2026b

Set left boundary of lane in RoadRunner HD Map

Since R2022b

Syntax

aLeftBoundary = leftBoundary(aLane,laneBoundaryID)

aLeftBoundary = leftBoundary(aLane,laneBoundaryID,Name=Value)

Description

aLeftBoundary = leftBoundary(aLane,laneBoundaryID) sets a boundary with ID laneBoundaryID to the LeftLaneBoundary (RoadRunner) property of the lane and returns it.

aLeftBoundary = leftBoundary(aLane,laneBoundaryID,Name=Value) sets options using one or more name-value arguments.

Examples

Set Left Boundary to a Lane in RoadRunner HD Map

Create an empty RoadRunner HD Map by calling the roadrunnerHDMap object.

rrMap = roadrunnerHDMap()

rrMap = 
  roadrunnerHDMap with properties:

Set the left lane boundary of the lane using the leftBoundary function.

leftBoundary(rrMap.Lanes,"LaneBoundaryL");

Input Arguments

aLane — Lane properties of road

roadrunner.hdmap.Lane object

Lane properties of a road, specified as a roadrunner.hdmap.Lane (RoadRunner) object.

Example: aLane= roadrunner.hdmap.Lane(ID="Lane1", Geometry=[-0.782 -1.56;50.78 23.43], LaneType="Driving", TravelDirection="Forward") creates a lane with properties lane id, coordinates defining lane geometry, lane type, and driving direction.

laneBoundaryID — ID of left lane boundary

character vector | string scalar

ID of the left lane boundary, specified as a string.

Example: leftBoundary(rrMap.Lanes,"LaneBoundaryL") assigns the left boundary with an id LaneBoundaryL to a lane in a RoadRunner HD Map.

Data Types: char | string

Name-Value Arguments

Specify optional pairs of arguments as Name1=Value1,...,NameN=ValueN, where Name is the argument name and Value is the corresponding value. Name-value arguments must appear after other arguments, but the order of the pairs does not matter.

Example:

Alignment — Type of alignment

character vector | string scalar

Type of alignment between linked objects, specified as a character vector or string scalar. The type of alignment is specified as one of the following strings: "Unspecified", "Forward", or "Backward".

Example: alref= roadrunner.hdmap.AlignedReference(Reference=ref, Alignment="Forward") creates the aligned reference for Lane2 with "Forward" alignment.

Data Types: char | string

Output Arguments

aLeftBoundary — Linkage information for left boundary of lane

roadrunner.hdmap.AlignedReference object

Linkage information for the left boundary of the lane, specified as a roadrunner.hdmap.AlignedReference (RoadRunner) object.
