Kenneth Greenshields

Kenneth Greenshields was a pioneer in traffic flow theory who introduced the concept of a fundamental diagram relating vehicle speed, flow, and density. He studied how traffic behaves under different conditions, demonstrating that as vehicle density increases, speed decreases, and eventually traffic becomes congested. His work helped in understanding the capacity of roads and how to manage congestion effectively. By modeling traffic in this way, Greenshields contributed to the development of modern transportation planning and traffic engineering, enabling better design and control of roads to improve safety and efficiency.
