...but roads are at least as subsidized as transit, and a new report from the Pew subsidiary Subsidyscope today demonstrates it nicely. At their height, highways were paid for by around 71% user fees (gas taxes, registration fees, etc.), and today these fees account for less than half of all highway spending. This is a level of subsidy slightly higher than Metrolink (as Metrolink users pay for ~50% of the service through fares, but ~10% of costs are covered by miscellaneous income such as trackage rights).
And let's make sure this is clear- this report is talking only about HIGHWAYS. Most of that gas tax that you (or your less enlightened friends, if you're car-free) pay goes into highways, which leaves surface streets to be taken care of by sales taxes, property taxes, and other outlays from the local government's general fund. The Victoria Transportation Policy Institute estimates that user fees account for less than 4% of local street expenditures. Remember, RTA riders pay a state-mandated 20% of the cost of their ride.
