By individual items: there's 6 items in narrowing, which I think is reasonable to say don't increase maintenance. There's 8 vertical deflections, which are all increasing. There's three in horizontal deflection, I'll give you roundabouts (I've argued enough about those elsewhere), so that's 2 more increasing and 1 not. For blocking, there's four, all of which are likely to increase travel distance.

So 6 + 1 = 7 vs 8 + 2 + 4 = 14. 7 out of 21 is the vast majority?

Pot holes clearly fit under vertical and horizontal deflection. Possibly block or restrict access. Deferred maintenance could be a general category of traffic calming.
