Traffic Regulator Ground-truth Information of the City of Hannover, Germany

This dataset contains the ground-truth intersection regulators for a majority of intersections of the city of Hannover, Germany. The ground-truth information is used in order to apply machine learning techniques on (car) GPS trajectory data in order to automatically detect the intersection regulation.  The GPS trajectories related to specifically this dataset are (also) available under: https://doi.org/10.25835/9bidqxvl ## Data Acquisition The ground-truth information are acquired by visiting them on-site and apply manual labeling of each intersection arm individually. Furthermore, satellite images and street-level images were considered but only on a minor degree as on-site labeling is found to be more precise and up-to-date. ## Related Publications: * __Zourlidou, S., Sester, M. and Hu, S.
