Missing bus lines in Trentino; OK to add these?


Looking at OpenStreetMap in Trentino whilst preparing for a holiday I’ve noticed that a number of bus lines are missing or incomplete around Riva del Garda. Is it permissible to use the information on the website of Trentino Trasporti (like this line) to add these?

I think that those data can’t be used because in this page they say that are licensed with a CC-BY-SA 2.0 which I think is not compatible with OSM.

Is there another source for this data?

You could try asking on the Trentino ML.
