Does the NSW Government Speed Zone data have a licence suitable for importing into OSM? Also, is it generally accurate? https://opendata.transport.nsw.gov.au/dataset/speed-zones https://opendata.transport.nsw.gov.au/dataset/road-segment-data-from-datansw
The reason I ask is that I recently came across a few roads with speed zones updated based on this data. The biggest problem is that the changes made in these three changesets were incorrect (i.e. the previously surveyed maxspeeds were updated from this data, but on survey in December 2023 the original surveyed maxspeed was the correct one). https://www.openstreetmap.org/changeset/129760120 https://www.openstreetmap.org/changeset/129759614 https://www.openstreetmap.org/changeset/129759603 Other changesets have been made based on this data, but I haven’t checked the accuracy of them.
