This undated photo provided by the University of Michigan College of Engineering shows vehicles as they drive through the Old Woodward Avenue and East Maple signalised intersection, which was retimed using the Optimised Signal as a Service (OSaaS), in Birmingham, Mich. Smarter vehicles could mean some of the most dramatic changes for the traditional traffic signal since the yellow light was added more than a century ago. — University of Michigan College of Engineering via AP
As cars and trucks get smarter and more connected, the humble lights that have controlled the flow of traffic for more than a century could also be on the cusp of a major transformation.
Researchers are exploring ways to use features in modern cars, such as GPS, to make traffic safer and more efficient. Eventually, the upgrades could do away entirely with the red, yellow and green lights of today, ceding control to driverless cars.
Uh-oh! Daily quota reached.
