๐Ÿ“Œ Context is King

Traffic lights have governed city flow for over a centuryโ€”but their days may be numbered. Researchers are exploring how AI-powered, connected vehicles could render traditional traffic signals obsolete, replacing red, yellow, and green with something altogether smarterโ€”or even invisible.

A research project at the University of Michigan suggests that a new system, perhaps even a โ€œwhite lightโ€ for automated vehicle coordination, could arrive sooner than expected. The age of smart infrastructure may require us to rethink what traffic even looks like.

๐Ÿง  In Focus

AI-powered traffic control offers a future with fewer stops, smoother rides, and fewer accidents. In such systems, autonomous vehicles would negotiate flow in real-time, rather than waiting at rigid, time-based signals.

But the shift isnโ€™t just technicalโ€”itโ€™s cultural. Our social contract with traffic assumes humans need rigid rules to behave safely. A system that hands over control to machines challenges deeply held ideas about trust, agency, and responsibility on the road.
