The Bottom-Up Revolution

Ohio’s Traffic Granny Takes On Dangerous Neighborhood Streets

April 21, 2026·15 min
Episode Description from the Publisher

Barbara Didrichsen, known locally as “Traffic Granny,” describes how everyday walks filled with close calls in her Pleasant Ridge neighborhood in Cincinnati, Ohio pushed her to start documenting crashes and traffic problems on her streets. She and Norm talk through simple first steps, like signs and flags, and how they used those results to argue for stronger engineering fixes. Their conversation shows what long-term, resident-led traffic calming looks like on the ground.
