In the early 1990s, transportation politics at both the state and federal levels was often fairly simple: an all-powerful Road Gang (made up of real estate developers and road contractors) typically got whatever it wanted, rolling over a much weaker pro-transit coalition of environmentalists and urban politicians.
I occasionally have speculated that our aging society would lead to increased transit ridership, as seniors lost the ability to drive. But I recently discovered that seniors are actually less likely to use public transit than the general public. One study by the American Public Transit Association showed that 6.7% of transit riders are over 65 (as opposed to 12.4% of all Americans).(1) The oldest Americans are even more underrepresented on America's buses and trains: only 1.5% of transit riders are over 80, about half their share of the population (2). The only other age group that is underrepresented on public transit is Americans under 18.
