The arteries of modern metropolises are their transportation networks, and what makes this vast system operate efficiently is the invisible flow of data and the wisdom of algorithms. The core of intelligent transportation systems lies in the real-time collection of massive amounts of data, such as traffic flow, speed, and accidents, by sensors throughout the road network, uploading this data to a cloud platform. Powerful algorithms perform millisecond-level analysis, prediction, and decision-making on this data, dynamically adjusting traffic light timings, issuing route guidance, and scheduling public transportation. Like an invisible "traffic brain," it coordinates the travel of thousands of individuals, achieving optimal overall system efficiency. Understanding this process is understanding the operating logic of future cities. Our "Never-Ending Flow" interactive exhibit condenses this grand system into an intuitive physical simulation on a compact 1.25-meter-side platform. Pressing
