Since R2022b

Syntax

aPredecessor = addPredecessor(aLane,predecessorID)

aPredecessor = addPredecessor(aLane,predecessorID,Name=Value)

Description

aPredecessor = addPredecessor(aLane,predecessorID) adds a predecessor with ID predecessorID to the Predecessors (RoadRunner) property of the lane and returns it.

example

aPredecessor = addPredecessor(aLane,predecessorID,Name=Value) sets options using one or more name-value arguments.

    Reference: [1×1 roadrunner.hdmap.Reference]
    Alignment: Unspecified

Input Arguments

collapse all

`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.

`predecessorID` — ID of predecessor lane
character vector | string scalar

ID of the predecessor lane, specified as a string.

Example: addPredecessor(rrMap.Lanes(2),"Lane1") assigns Lane1 as the predecessor of Lane2 in a RoadRunner HD Map.

Data Types: char | string

Name-Value Arguments

collapse all

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

`aPredecessor` — Linkage information for preceding lanes
`roadrunner.hdmap.AlignedReference` object

Linkage information for preceding lanes, specified as a roadrunner.hdmap.AlignedReference (RoadRunner) object.
