Traffic savant, cartoonist, and author Andy Singer (https://www.andysinger.com/) explains the MUTCD,

'The Manual on Uniform Traffic Control Devices for Streets and Highways (which) defines the standards used by road managers nationwide to install and maintain traffic control devices on all public streets, highways, bikeways, and private roads open to public travel(https://mutcd.fhwa.dot.gov/) .’ The ‘bible’ for traffic engineers, the Manual is dangerously auto-centric, and undergoing a process of revision which only happens every 10-15 years.

Andy also talks about his work with the St. Paul bicycle coalition which he founded, his cartoon career, hopes for the current administration, and thoughts about the future.

Then: an interview by Andrea Learned, climate action leadership strategist, with David Miller, former Mayor of Toronto, Director of International Diplomacy for C40 Cities, and author of Solved: How the World’s Great Cities Are Fixing the Climate Crisis.
