Hi,

It looks like you're marking roads as trunk simply because they're divided. Can you confirm that this is the case? 

Physical characteristics should have no impact on the classification of a road, except for motorways. If a road is not quite a motorway, but is still very upgraded, it might deserve expressway=yes, but not necessarily highway=trunk. If the road is divided but still has a lot of access (e.g. driveways into shopping areas), it probably doesn't deserve expressway=yes either. You may however tag these as dual_carriageway=yes to mark this feature.

For more information on road classification tagging, please consult these pages:

Please let me know if you have any questions, and I'll be happy to help as best I can.

Best,
John
