| # InterSim: Full Unity Project |
|
|
| The complete Unity project for **InterSim: Innovative Intersection Digital Twins for Human-in-the-Loop Driving Simulation**. |
|
|
| [Paper (arXiv)](https://arxiv.org/abs/2611.05968) · [Project page](https://purduedigitaltwin.github.io/InterSim/) · [Code (GitHub)](https://github.com/PurdueDigitalTwin/InterSim-Simulator) · [Zenodo](https://zenodo.org/records/23889549) |
|
|
| ## Contents |
|
|
| `InterSim-FullProject.zip` (about 3.6 GB) is the complete Unity 6000.6.6f1 project with digital twins of five innovative intersections: Displaced Left Turn (DLT), Reduced Conflict Intersection (RCI), Roundabout Interchange (RBI), Diverging Diamond Interchange (DDI) and Two-Lane Roundabout (RAB). Besides the scripts, scenes and settings that are also on GitHub, it includes the textures, 3D models (including the vehicles) and audio that the GitHub repository leaves out. |
|
|
| If you only want to try the simulator, download a prebuilt package from [GitHub Releases](https://github.com/PurdueDigitalTwin/InterSim-Simulator/releases) instead. No access request is needed for those. |
|
|
| ## Access |
|
|
| The files are gated. Fill in the form on this page and agree to the terms, and we will review your request. Access is for research use only, and the project and its vehicle models must not be redistributed. |
|
|
| ## Download and open |
|
|
| 1. Once your request is approved, download `InterSim-FullProject.zip` from the *Files and versions* tab, or from a terminal: |
| ```bash |
| pip install -U huggingface_hub |
| hf auth login |
| hf download James55158075/InterSim InterSim-FullProject.zip --repo-type dataset --local-dir . |
| ``` |
| 2. Extract the zip. Install [Unity Hub](https://unity.com/download), click *Add* → *Add project from disk* and select the extracted `InterSim` folder. Unity Hub will offer to install the required editor version (6000.6.6f1). |
| 3. Open the project (the first import takes a while), open `Assets/Scenes/Main/MainMenu.unity` and press **Play**. |
|
|
| To get later updates to the scripts and scenes, connect the extracted project to the GitHub repository as described in its [README](https://github.com/PurdueDigitalTwin/InterSim-Simulator#open-the-unity-project). |

| ## License |
|
|
| The InterSim code is released under the MIT License (see the [GitHub repository](https://github.com/PurdueDigitalTwin/InterSim-Simulator)). This full project also contains commercial vehicle models purchased from TurboSquid and third-party Unity packages (for example EasyRoads3D, Edy's Vehicle Physics, Simple Waypoint System, Traffic Lights System, TerrainFormer, DOTween and Unity Standard Assets), which remain under their own licenses. The full project is shared for research use only and may not be redistributed. |
