US Highway

US highway 3D environment

Description

The US Highway scene is a 3D environment of a US highway that contains barriers, cones, and traffic signs. The scene is created using RoadRunner.

For information about additional scenes, see 3D Scenes for Simulation in Unreal Engine Environment.

Setup

To simulate a driving maneuver in the US highway scene:

1. Add a Simulation 3D Scene Configuration block to your Simulink^® model.

2. In this block, set the Scene source parameter to Default Scenes.

3. View the currently available scenes in the Scene name parameter. If the scene is not available, you must install it.

4. To install the scene:

   1. Click Install.

   2. In the Add-on installer dialog box, select the scene.

   3. Click Next and follow the prompts.

   MATLAB^® restarts after the scene is installed.

5. Select the scene name from the Scene name parameter.

Layout

The scene uses the world coordinate system to locate objects. The active area of the scene contains the road.

World Coordinate System

The 3D visualization environment uses a world coordinate system with axes that are fixed in the inertial reference frame.

Axis	Description
X	Forward direction of the vehicle Roll — Right-handed rotation about X-axis
Y	Extends to the right of the vehicle, parallel to the ground plane Pitch — Right-handed rotation about Y-axis
Z	Extends upwards Yaw — Left-handed rotation about Z-axis

Tips

• If you have the Vehicle Dynamics Blockset™ Interface for Unreal Engine Projects support package, then you can modify this scene. In the Unreal Engine project file that comes with the support package, this scene is named USHighway.

Version History

Introduced in R2018b

R2025a: Install scene

You can install the US Highway scene if it is not available in the Scene view parameter list. To install the scene, use the Install option in the Simulation 3D Scene Configuration block.

R2022b: Scene rendered using RoadRunner

Starting from R2022b, the US Highway scene in the Unreal Engine 3D environment is rendered using RoadRunner. As a result, the locations of scene objects, including cones and parked vehicles, are moved from their pre-R2022b locations.
