标题： DigiT4TAF -- Bridging Physical and Digital Worlds for Future Transportation Systems

摘要： 在未来，移动性将受到数字化日益广泛应用的强烈影响。 不仅个体道路使用者将高度互联，道路及其相关基础设施也将如此。 在这一点上，数字孪生变得特别有吸引力，因为与基本模拟不同，它提供了一种连续的双向连接，将现实和虚拟环境联系起来。 本文描述了用于开发测试区域自动驾驶-巴登-符腾堡（TAF-BW）数字孪生的数字重建。 TAF-BW提供了各种不同的道路路段，从高交通量的城市交叉口和隧道到多车道高速公路。 测试区域配备了全面的车对一切（V2X）通信基础设施以及多个配备摄像头传感器的智能交叉口，以促进实时交通流量监测。 通过在交叉口提取对象列表，实现了作为数字孪生输入的真实数据生成。 这一过程通过结合使用智能基础设施的摄像机图像和安装在测试车辆上的激光雷达传感器得以实现。 通过统一的接口，可以重新模拟现实世界中交通参与者的检测记录。 此外，还讨论了仿真框架的设计和重建过程。 所产生的框架已公开供下载和使用，网址为：https://digit4taf-bw.fzi.de 该演示使用两个案例研究来说明数字孪生及其接口的应用：分析交通信号系统以优化交通流量，以及在通信领域模拟与安全相关的场景。 显示英文摘要

摘要： In the future, mobility will be strongly shaped by the increasing use of digitalization. Not only will individual road users be highly interconnected, but also the road and associated infrastructure. At that point, a Digital Twin becomes particularly appealing because, unlike a basic simulation, it offers a continuous, bilateral connection linking the real and virtual environments. This paper describes the digital reconstruction used to develop the Digital Twin of the Test Area Autonomous Driving-Baden-W\"urttemberg (TAF-BW), Germany. The TAF-BW offers a variety of different road sections, from high-traffic urban intersections and tunnels to multilane motorways. The test area is equipped with a comprehensive Vehicle-to-Everything (V2X) communication infrastructure and multiple intelligent intersections equipped with camera sensors to facilitate real-time traffic flow monitoring. The generation of authentic data as input for the Digital Twin was achieved by extracting object lists at the intersections. This process was facilitated by the combined utilization of camera images from the intelligent infrastructure and LiDAR sensors mounted on a test vehicle. Using a unified interface, recordings from real-world detections of traffic participants can be resimulated. Additionally, the simulation framework's design and the reconstruction process is discussed. The resulting framework is made publicly available for download and utilization at: https://digit4taf-bw.fzi.de The demonstration uses two case studies to illustrate the application of the digital twin and its interfaces: the analysis of traffic signal systems to optimize traffic flow and the simulation of security-related scenarios in the communications sector.
