Cincinnati is the 24th largest metro area in the country. Compared to similarly sized cities, our transit ridership is much lower. Denver, Pittsburgh, Portland, and Cleveland all have rail systems and they all have over double the transit ridership of bus-only Cincinnati. Two things are clear, rail attracts more riders than bus systems, and cities of a similar size to Cincinnati are large enough to support rail.
Note: Pittsburgh Yearly Ridership data is extrapolated from daily ridership data. Cincy USA includes both Metro and TANK.
