Their technology helps cities reduce congestion, prevent accidents, and improve travel times - all without replacing existing infrastructure.We discuss:- How AI-powered traffic lights simulate and predict vehicle movement in real-time- Key safety features: Dilemma Zone Protection and Dynamic All-Red Extensions- How their system adapts to fog, rain, and poor visibility- Handling emergency vehicles and ensuring software reliability- Their first deployment in San Anselmo, California, and the results: 30% reduction in rush-hour wait times- How Roundabout found its first city customer and built trust in a government market-  Collin’s background at Google and Verily, and what it’s like to go through Y Combinator- The massive market potential - over 330,000 intersections in the U.S. alone- Roundabout’s long-term vision for safer, smarter citiesIf you work in city planning or transportation innovation - or just want to see how AI is shaping real-world infrastructure - this is a must-watch episode.📩 Interested in pilot programs?
