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

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.

Locations

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).

R2022b: 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.
