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]

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]

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)

poses=2×1 struct array with fields:
    ActorID
    Position
    Velocity
    Roll
    Pitch
    Yaw
    AngularVelocity

profiles = actorProfiles(scenario)

profiles=2×1 struct array with fields:
    ActorID
    ClassID

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 the roadBoundaries 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 the roadBoundaries function. Specify the scenario as the input argument.

rbScenario = roadBoundaries(scenario);

Obtain the road boundaries in ego vehicle coordinates by using the driving.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 a driving scenario containing a car and pedestrian on a straight road. Then, create and display the lane markings of the road on a bird's-eye plot.

scenario = drivingScenario;

lm = [laneMarking('Solid')
      laneMarking('Dashed','Length',2,'Space',4)
      laneMarking('Solid')];
l = lanespec(2,'Marking',lm);
road(scenario,[0 0 0; 25 0 0],'Lanes',l);

ped = actor(scenario,'ClassID',4,'Length',0.2,'Width',0.4,'Height',1.7);
car = vehicle(scenario,'ClassID',1);
trajectory(ped,[15 -3 0; 15 3 0],1);
trajectory(car,[car.RearOverhang 0 0; 25-car.Length+car.RearOverhang 0 0],10);

plot(scenario)

chasePlot(car)

bep = birdsEyePlot('XLim',[-25 25],'YLim',[-10 10]);
olPlotter = outlinePlotter(bep);
lbPlotter = laneBoundaryPlotter(bep);
lmPlotter = laneMarkingPlotter(bep,'DisplayName','Lanes');
legend('off');
while advance(scenario)
    rb = roadBoundaries(car);
    [position,yaw,length,width,originOffset,color] = targetOutlines(car);
    [lmv,lmf] = laneMarkingVertices(car);
    plotLaneBoundary(lbPlotter,rb);
    plotLaneMarking(lmPlotter,lmv,lmf);
    plotOutline(olPlotter,position,yaw,length,width, ...
        'OriginOffset',originOffset,'Color',color);
