public transit benefits the community/region more so than any individual benefit, so I don't think cost per passenger is appropriate either.

Sometimes basic science research funding is framed in terms of "this program generated $10 of economic activity for every dollar spent." Social programs sometimes measured this way too. The term for this escapes me at the moment, but I think it would be more useful?

This type of cost-benefit analysis (or economic multiplier calculation) is also used to justify public subsidy of sports stadiums and the like. Unfortunately, these analyses always use overly optimistic assumptions, and fall victim to the broken windows fallacy.
