The uniD dataset is an innovative collection of naturalistic road user trajectories, captured within the RWTH Aachen University campus using drone technology to address common challenges such as occlusions found in traditional traffic data collection methods. It meticulously documents the movement and classifies each road user by type. Employing cutting-edge computer vision algorithms, the dataset ensures high positional accuracy. Its utility spans various applications, from predicting road user behavior and modeling driver actions to conducting scenario-based safety checks for automated driving systems and facilitating the data-driven design of Highly Automated Driving (HAD) system components.
