Yes, definitely. From what I understand, transit west of downtown leaves a LOT to be desired.  (And the airport is west of downtown.) Pittsburgh’s transit isn’t as good as it could and should be — but that one busway east of downtown is easily overlooked (and better than bus transit usually is most places). There are also some busways south of downtown too — which I know next to nothing about — and I have no idea how efficient they are (how isolated from other vehicles they are — or aren’t). PGH’s transit is a mixed bag overall — but still better than quite a number of other cities that aren’t bigger than PGH.
