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) roadcenters = [400 400 0; 0 0 0]; road(scenario,roadcenters)
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,'Position',[700 0 0],'Length',3,'Width',2,'Height',1.6);
Position the bicycle farther down the road.
bicycle = actor(scenario,'Position',[706 376 0]','Length',2,'Width',0.45,'Height',1.5);
Plot the scenario.

profiles— Actor profiles
Actor profiles, returned as a structure or as an array of structures. Each structure contains the physical and radar characteristics of an actor.
The actor profile structures have these fields.
|Scenario-defined actor identifier, specified as a positive integer.|
|Classification identifier, specified as a nonnegative integer. |
|Length of actor, specified as a positive real scalar. Units are in meters.|
|Width of actor, specified as a positive real scalar. Units are in meters.|
|Height of actor, specified as a positive real scalar. Units are in meters.|
|Offset of actor's rotational center from its geometric center, specified as a real-valued vector of the form [x,y, z]. The rotational center, or origin, is located at the bottom center of the actor. For vehicles, the rotational center is the point on the ground beneath the center of the rear axle. Units are in meters.|
|Vertices is a mesh representation of the actor specified as a n-by-3 matrix of vertices. Each row in the matrix defines a point in 3-D space.|
|Faces is a mesh representation of the actor specified as a m-by-3 matrix of integers. Each row of the faces is a triangle defined by the vertex IDs, which are the row numbers of vertices.|
|Radar cross-section (RCS) pattern of actor, specified as a
|Azimuth angles corresponding to rows of |
|Elevation angles corresponding to rows of |
