I was just reading through IndyGo’s proposed 2013 budget (I know, that’s what I do). This chart stuck out to me (fixed route is IndyGo’s term for any bus that’s on a constant route, which excluded the short paratransit busses for the disabled and express routes like the GreenLine, Red Line, or Carmel / Fishers busses):
You can see and read more from their report and presentation files at IndyGo’s site. Also interesting to note that Columbus, Ohio has the same cost to ride a bus as us and about the same number of stops and about the same number of people living in the metro area, but has twice the riders we do simply because the routes they do have are served with higher frequency. A clear “build it and they will come” use case.
