For Cities, ‘Transit Is Existential’

In a new edition of his book “Human Transit,” Jarrett Walker confronts the US public transportation crisis (and Elon Musk) in an era of disruption and innovation.

Thirteen years after Human Transit was first published to widespread acclaim among transit professionals and advocates, the Portland, Oregon-based consultant (who’s also an occasional Bloomberg CityLab contributor) has augmented the book’s focus on urban geometry, route-planning, and passenger decision-making with material covering emergent topics, such as the startups and venture capitalists that have targeted transit agencies over the last decade. Walker is wary of their innovations.
