We are releasing 10.4k turn restriction detections located across 5.2k intersections for the OpenStreetMap community.
These turn restriction detections were sourced by applying our machine learning computer vision models to Bing Streetside imagery. Mapbox has acquired the right to contribute these detections to OSM.
“Detections” are not really the same thing as turn restrictions. Rather, they are suspected, but unverified turn restrictions. We are planning to manually verify these turn restrictions, and our data team is working through the list, but the first pass produced thousands of candidates, so verification will take a while. We do think these can be useful to the OSM community, who may wish to move faster on improving OSM based on these detections.
To be clear, the Streetside imagery is not available for direct editing by the community at large. However, subject to its terms and conditions, it can be used for personal reference for examining the source of the detections, so we have included URLs to the image associated with each detection.
