This week on the Strong Towns Podcast, host Chuck Marohn welcomes back a special return guest: Jarrett Walker, head of Jarrett Walker + Associates, a transit-planning firm based in Portland, Oregon. Walker has been a consultant in public transit network, design, and policy for many decades now, and has worked all across North America and other countries worldwide. He’s also the author of the book Human Transit: How Clearer Thinking about Public Transit Can Enrich Our Communities and Our Lives, as well as the blog Human Transit.

Recently while doing his end-of-the-year desk cleaning, Chuck came across an article that Walker wrote in 2018 for the Journal of Public Transportation titled “To Predict with Confidence, Plan for Freedom.” Upon rereading it (for the fourth time), Chuck knew he wanted to talk to Walker about this piece.

So, join in for this conversation about the limitations of prediction, starting with a story seven or eight years ago, when Walker was developing a proposed redesign for the bus network in Houston…
