About this episode

Jarrett Walker discusses the tradeoffs cities face in public transit regarding frequency, coverage, and affordability.

Putting a route near every community sounds fair until the buses only arrive once an hour. Jarrett Walker, author of Human Transit and principal of the firm helping Des Moines rethink its bus network, explains why cities cannot maximize frequency, coverage, and affordability at the same time. In Des Moines, the tradeoff comes with a 10% service cut, long waits, indirect routes, and streets that make some bus stops difficult or dangerous to reach. To understand whether the system is useful enough for people to actually rely on it, Walker asks a more revealing question: how much of the city can someone reach within a reasonable amount of time?
