This dataset contains the ground-truth intersection regulators for all intersections crossed by the open GPS trajectory data of Chicago, published on [Mapconstruction.org](http://mapconstruction.org). ## Data Acquisition The ground-truth data is generated by manually inspecting images at the intersections crossed by the published trajectory dataset on [Mapconstruction.org](http://mapconstruction.org). These images are derived from [mapillary.com](https://www.mapillary.com/) at the respective intersections. Satellite images are investigated as an additional data source, if needed. This procedure result in labels for each intersection arm. ## Related Publications: * __Zourlidou, S., Sester, M. and Hu, S.
