- It's certainly impossible to dispute that shared transportation on a
- limited number of routes appears cheaper than individual transport on a
- wider number of routes, but can be misleading to make that comparison.
- First, it's very difficult to assign costs given the difficulty of
- determining the cost vs. utility of the various public goods involved
- (roads, pollution, etc.) It's easy, though, to look at actual individual
- behavior to see how people act in evaluating the relative utility and
- cost of the different systems.
-
- In public transportation systems the bulk of the cost is born equally
- by everyone regardless of its utility to them. I don't think you can
- find a public transportation system anywhere in the world that covers
- its operation costs from revenues, let alone its capitalization, thus
- operating revenues and capital costs must be recovered via general revenues.
- This is a strong argument that people would not actually pay the real costs
- of public transit if they were assigned to the end users only.
-
- But people are willing to pay a larger fraction of the cost of individual
- transport, above and beyond capital and operational costs. The pay tax on
- the vehicle, license fees, government mandated insurance and so forth.
- Whether auto owners actually cover the costs of public roads is debateable,
- but the most common form of public transport uses the same roads.
-
- That leaves the costs of pollution. This is typically taxed in most states,
- too, in the form of air-quality testing and mandated controls.
-
- I don't know if it's possible to assign the actual costs of public versus
- private transportation in a way that all will agree, but I think a very good
- case can be made for the argument that in the case of private transportation
- there is more perceived utility and more willingness to assume direct costs.
