Examples
Create and Display Road Boundaries
Create a driving scenario containing a figure-8 road specified in the world coordinates of the scenario. Convert the world coordinates of the scenario to the coordinate system of the ego vehicle.
Create an empty driving scenario.
scenario = drivingScenario;
Add a figure-8 road to the scenario. Display the scenario.
roadCenters = [0 0 1 20 -20 1 20 20 1 -20 -20 1 -20 20 1 0 0 1]; roadWidth = 3; bankAngle = [0 15 15 -15 -15 0]; road(scenario,roadCenters,roadWidth,bankAngle); plot(scenario)
Add an ego vehicle to the scenario. Position the vehicle at world coordinates (20, –20) and orient it at a –15 degree yaw angle.
ego = actor(scenario,'ClassID',1,'Position',[20 -20 0],'Yaw',-15);
Obtain the road boundaries in ego vehicle coordinates by using theroadBoundaries
function. Specify the ego vehicle as the input argument.
rbEgo1 = roadBoundaries(ego);
Display the result on a bird's-eye plot.
bep = birdsEyePlot; lbp = laneBoundaryPlotter(bep,'DisplayName','Road'); plotLaneBoundary(lbp,rbEgo1)
Obtain the road boundaries in world coordinates by using theroadBoundaries
function. Specify the scenario as the input argument.
rbScenario = roadBoundaries(scenario);
Obtain the road boundaries in ego vehicle coordinates by using thedriving.scenario.roadBoundariesToEgo
function.
rbEgo2 = driving.scenario.roadBoundariesToEgo(rbScenario,ego);
Display the road boundaries on a bird's-eye plot.
bep = birdsEyePlot; lbp = laneBoundaryPlotter(bep,'DisplayName','Road boundaries'); plotLaneBoundary(lbp,{rbEgo2})
Create Driving Scenario with Multiple Actors and Roads
Create a driving scenario containing a curved road, two straight roads, and two actors: a car and a bicycle. Both actors move along the road for 60 seconds.
Create the driving scenario object.
scenario = drivingScenario('SampleTime',0.1','StopTime',60);
Create the curved road using road center points following the arc of a circle with an 800-meter radius. The arc starts at 0°, ends at 90°, and is sampled at 5° increments.
angs = [0:5:90]'; R = 800; roadcenters = R*[cosd(angs) sind(angs) zeros(size(angs))]; roadwidth = 10; road(scenario,roadcenters,roadwidth);
Add two straight roads with the default width, using road center points at each end.
roadcenters = [700 0 0; 100 0 0]; road(scenario,roadcenters)
ans = Road with properties: Name: "" RoadID: 2 RoadCenters: [2x3 double] RoadWidth: 6 BankAngle: [2x1 double] Heading: [2x1 double]
roadcenters = [400 400 0; 0 0 0]; road(scenario,roadcenters)
ans = Road with properties: Name: "" RoadID: 3 RoadCenters: [2x3 double] RoadWidth: 6 BankAngle: [2x1 double] Heading: [2x1 double]
Get the road boundaries.
rbdry = roadBoundaries(scenario);
Add a car and a bicycle to the scenario. Position the car at the beginning of the first straight road.
car = vehicle(scenario,'ClassID',1,'Position',[700 0 0],...'Length',3,'Width',2,'Height',1.6);
Position the bicycle farther down the road.
bicycle = actor(scenario,'ClassID',3,'Position',[706 376 0]',...'Length',2,'Width',0.45,'Height',1.5);
Plot the scenario.
plot(scenario,'Centerline','on','RoadCenters','on'); title('Scenario');
Display the actor poses and profiles.
poses = actorPoses(scenario)

Input Arguments
scenario
—Driving scenario
drivingScenario
object
Driving scenario, specified as adrivingScenario
object.
Name-Value Arguments
Specify optional pairs of arguments asName1=Value1,...,NameN=ValueN
, whereName
is the argument name andValue
is the corresponding value. Name-value arguments must appear after other arguments, but the order of the pairs does not matter.
Before R2021a, use commas to separate each name and value, and encloseName
in quotes.
Example:plot(sc,'Centerline','on','RoadCenters','on')
displays the center line and road centers of each road segment.
Parent
—Axes in which to draw plot
Axes
object
Axes in which to draw the plot, specified as the comma-separated pair consisting of'Parent'
and anAxes
object. If you do not specifyParent
, a new figure is created.
Centerline
—Display center line of roads
'off'
(default) |'on'
Display the center line of roads, specified as the comma-separated pair consisting of'Centerline'
and'off'
or'on'
. The center line follows the middle of each road segment. Center lines are discontinuous through areas such as intersections or road splits.
RoadCenters
—Display road centers
'off'
(default) |'on'
Display road centers, specified as the comma-separated pair consisting of'RoadCenters'
and'off'
or'on'
. The road centers define the roads shown in the plot.
Waypoints
—Display actor waypoints
'off'
(default) |'on'
Display actor waypoints, specified as the comma-separated pair consisting of'Waypoints'
and'off'
or'on'
. Waypoints define the trajectory of the actor.
Meshes
—Display actor meshes
'off'
(default) |'on'
Display actor meshes instead of cuboids, specified as the comma-separated pair consisting of'Meshes'
and'off'
or'on'
.
行为orIndicators
—行为ors around which to draw indicator
[]
(default) |vector of行为orID
integers
行为ors around which to draw indicators, specified as the comma-separated pair consisting of'ActorIndicators'
and a vector of行为orID
integers. The driving scenario plot draws circles around the actors that have the specified行为orID
values. Each circle is the same color as the actor that it surrounds. The circles are not sensor coverage areas.
Use this name-value pair to highlight the ego vehicle in driving scenarios that contain several vehicles.
ParkingLotEdges
—Display parking lot edge numbers
'off'
(default) |'on'
Display parking lot edge numbers, specified as the comma-separated pair consisting of'ParkingLotEdges'
and'off'
or'on'
. The order of the edge numbers is based on the order of the vertices defined in each parking lot.
