MIT: Red lights could someday be a thing of the past


As vehicles become more wirelessly connected, communicating with each other and the infrastructure around them, traffic lights may become an unecessary impediment in getting from A to B.



Instead of stopping for traffic lights, sensor-laden vehicles would communicate with each other and perform a kind of ballet around each other, according to a new study by MIT.



The study claims this kind of traffic-light-free transportation design, if it ever arrives, could allow twice as much traffic to use existing roads.
