roadrunner.hdmap.LaneGroup

Create lane groups in RoadRunner HD Map using MATLAB

Since R2022b

Description

A roadrunner.hdmap.LaneGroup object enables you to define a group of lanes with similar geometry in a RoadRunner HD Map scene model. The LaneGroup geometry is used as a general approximation for the geometry of the lanes contained within that group. The hierarchy of the lane elements is defined as:

• A lane group contains references to lanes.

• A lane has references to its boundaries and its connected lanes.

• A lane boundary has references to the lane markings.

Creation

Syntax

laneGroup = roadrunner.hdmap.LaneGroup()

laneGroup = roadrunner.hdmap.LaneGroup(Name=Value)

Description

laneGroup = roadrunner.hdmap.LaneGroup() creates an empty lane group collection.

laneGroup = roadrunner.hdmap.LaneGroup(Name=Value) sets the properties of the lane group collection using name-value pairs.

Properties

ID — ID of lane group

character vector | string scalar

ID of the lane group, specified as a character vector or string scalar.

Example: rrMap.LaneGroups= roadrunner.hdmap.LaneGroup(ID="LaneGroup1") creates a lane group with id LaneGroup1 in a RoadRunner HD Map.

Data Types: char | string

Geometry — 3D coordinates of geometric shape of lane group

three element vector

3D coordinates of the geometric shape of the lane group, specified as a three element vector, with double precision values.

Example: rrMap.LaneGroups= roadrunner.hdmap.LaneGroup(ID="LaneGroup1", Geometry=[-0.782 -1.56;50.78 23.43]) creates a lane group with id "LaneGroup1" and defines the coordinates for the geometric shape of the lane group.

Data Types: double

Lanes — Collection of lane references

array of roadrunner.hdmap.AlignedReference objects

Collection of lane references, specified as an array of roadrunner.hdmap.AlignedReference (RoadRunner) objects. This property defines the linkage information for lanes within the lane group.

Examples

Add Lane Group to RoadRunner HD Map

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

rrMap = roadrunnerHDMap()

rrMap = 
  roadrunnerHDMap with properties:

                Author: ""
            Projection: ""
    GeographicBoundary: [0×3 double]
                 Lanes: [0×1 roadrunner.hdmap.Lane]
        LaneBoundaries: [0×1 roadrunner.hdmap.LaneBoundary]
            LaneGroups: [0×1 roadrunner.hdmap.LaneGroup]
          LaneMarkings: [0×1 roadrunner.hdmap.LaneMarking]
             Junctions: [0×1 roadrunner.hdmap.Junction]
          BarrierTypes: [0×1 roadrunner.hdmap.BarrierType]
              Barriers: [0×1 roadrunner.hdmap.Barrier]
             SignTypes: [0×1 roadrunner.hdmap.SignType]
                 Signs: [0×1 roadrunner.hdmap.Sign]

Create the road lane group using the roadrunner.hdmap.LaneGroup object. Specify the lane information for the lane id.

rrMap.LaneGroups = roadrunner.hdmap.LaneGroup(ID="LaneGroup1")

rrMap = 
  roadrunnerHDMap with properties:

                Author: ""
            Projection: ""
    GeographicBoundary: [0×3 double]
                 Lanes: [0×1 roadrunner.hdmap.Lane]
        LaneBoundaries: [0×1 roadrunner.hdmap.LaneBoundary]
            LaneGroups: [1×1 roadrunner.hdmap.LaneGroup]
          LaneMarkings: [0×1 roadrunner.hdmap.LaneMarking]
             Junctions: [0×1 roadrunner.hdmap.Junction]
          BarrierTypes: [0×1 roadrunner.hdmap.BarrierType]
              Barriers: [0×1 roadrunner.hdmap.Barrier]
             SignTypes: [0×1 roadrunner.hdmap.SignType]
                 Signs: [0×1 roadrunner.hdmap.Sign]
