Hi Ankhbayar Ch,
I noticed you have been changing track ways to tertiary and secondary. Tertiary ways are typically used to “connect minor streets to more major roads” (https://wiki.openstreetmap.org/wiki/Tag:highway%3Dtertiary) and secondary ways are usually paved and support higher volumes of traffic (https://wiki.openstreetmap.org/wiki/Tag:highway%3Dsecondary). Since these roads aren’t paved and lead to minor agricultural areas I changed them to unclassified and track. What do you think of that classification for these roads?
