# Data repository

## Content

This repository consists of data from the Demonstrator "Hybrid Digital Shadow System for Pavement-Load Monitoring" as show case at the on-site review on 24 March 2026 (end of Phase I of the SFB/TRR 339).

A video animation of the Demonstrator is available on [sfbtrr339.de](https://www.sfbtrr339.de/files/sfb339/content/videos/Digital_shadow_showcase.mp4).


### file `CPM-data.zip`

This file contains the compressed output of the Cyber-Physical Mobility Lab.

### file `Demonstrator.zip`

This file contains a packaged Unreal Engine project including the 3D model of the WIM Research Site map and the data connection handlers detailed above, which hook into data streaming topics via ports of a local network in our project.
[Unreal Engine](https://www.unrealengine.com/en-US/download) can be downloaded for free.
The version is 5.2 and should be used to exclude potential compatibility issues.

### file `Demonstrator_manual.pdf`

These file contains the user manual of the Demonstrator setup.

### file `Python_scripts.zip`

These files contain test scripts for establishing a data connection to the Digital Shadow platform. 

### file `style_images.zip`

These files contain the different sign options of the sign gantry that can be installed. 

### file `WIM-data.csv`

This file contains the compressed output of the WIM Research Site.
