US City Block
US city block 3D environment
Description
The US City Block scene is a 3D environment of a US city block that contains 15 intersections and 30 traffic lights. The scene is rendered using RoadRunner.
Setup
To simulate a driving maneuver in this scene:
Add a Simulation 3D Scene Configuration block to your Simulink® model.
In this block, set the Scene source parameter to
Default Scenes
.Set the enabled Scene name parameter to
US city block
.
Layout
The scene uses the world coordinate system to locate objects.

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 |
Objects
Barrier
This table provides the object names and locations in the world coordinate system. Dimensions are in m.

Traffic Lights
The US City Block scene contains 30 traffic lights, two at each of the 15 intersections. Each intersection has a traffic light group. If you have the Customize 3D Scenes for Vehicle Dynamics Simulations for customizing scenes, you can control the timing of the traffic lights.
This table provides the traffic light names and locations in the world coordinate
system. Dimensions are in m. Only one of the traffic lights in the group can be green at a
time. The traffic lights are green for 10 s and yellow for 3 s. At the start of the
simulation, the first traffic lights in the group are green (for example,
SM_TrafficLights1_3
and SM_TrafficLights2_3
). The
second lights in the group are red (for example, SM_TrafficLights1_4
and SM_TrafficLights2_4
).

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
USCityBlock
.For more details on customizing scenes, see Customize 3D Scenes for Vehicle Dynamics Simulations.
Version History
Introduced in R2018bR2022b: Scene rendered using RoadRunner
Starting from R2022b, the US City Block 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.
