If you're saying the only criterion was average boardings per trip, I
don't think that's the case; the "scorecard" has a number of other
factors, including a number of "equity" considerations: service to
minority, low income, seniors (there's your "old women"), and disabled
populations, as well as "county coverage".

Analyzing all permutations of a route network isn't feasible, even if
you have reliable data on how many people get on and off at which stops.
Could they have done a more complex analysis?  Probably.  Would it have
been that much different?  I don't know.  Do you have any reason to
think it would?

Well...it definitely takes some imagination to talk about Mt. Lebanon-
Airport buses.

If you look at http://www.portauthority.org/PAAC/Portals/0/ServiceChange.pdf ,
you'll see that a number of routes are being truncated rather than eliminated
(12A, 13A, 13C, 16B, 17B, 18B, 21A...you can find the rest).

My pipeline, at this particular moment, is the following:
