Coordinating Traffic Lights

Melvin Friedman

Melvin Friedman’s team was tasked with designing road and traffic control systems that maximize traffic flow and minimize red-light wait time. This talk describes how they found a way to relieve bumper-to-bumper traffic on highways and build inexpensive uninterrupted flow roads that function like highways. Mathematica makes it possible to visualize this using the green wave on a red sea (GWRS) methodology.
