Milan Smart access, cleaner center Milan uses ‘smart access’ to its center – Area C. On workdays, only clean vehicles or vehicles with a permit are allowed into this zone. Area C uses number-plate recognition to enforce this. Thanks to real-time monitoring and dynamic enforcement, Milan is able to respond rapidly to traffic congestion or deteriorating air quality. Bogotá Digital twin The city for people, not for cars Every Sunday, Bogotá organizes Ciclovía, closing off more than 120 km of streets to cars. Ciclovía attracts more than a million people, who come to cycle, walk, run, or skate. Free gym lessons, performances, and health checks are provided along the route. Valencia is building a digital twin that simulates traffic and crowds in real time. This allows the city to virtually test measures, such as a new light railway route, temporary bans on cars, or closures due to major events. The system joins together data from sensors, public transport systems, and GPS using AI predictions. Valencia 19
