The new episode of “The Transit Effect” with Ken Jennings explores how transit expands opportunity for all

What does a subway ride have to do with the legacy of American music? What does a bus have to do with the Civil Rights Movement? In the newest episode of The Transit Effect, Ken Jennings explores how transit has shaped American history — and why access to a ride can mean access to opportunity. 

This is the fourth episode in a seven-part series examining how transit helps shape our cultures, economies, history, and communities. Future episodes will be released every few months through 2026.  

In this episode, you’ll see how transit has been more than transportation — it reflects both the barriers people face and the resilience communities show in response. Learn how public transit helped fuel cultural growth during the Harlem Renaissance, why Rosa Parks’ refusal to give up her bus seat became a turning point for the Civil Rights Movement, and how transportation access is still closely tied to opportunity today — including how Washington is investing in more reliable, affordable transit options.
