Submission + - MIT Study Shows Stop Lights Won't Be Necessary In The Future (computerworld.com) 1
Lucas123 writes: An MIT study based on mathematical modeling demonstrated a likely scenario in which high-tech vehicles using sensors to remain at a safe distance from each other as they move through a four-way intersection can eliminate the need for traffic lights in the future. By removing the waits caused by traffic lights, these so-called Slot-based Intersections speed up traffic flow.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.
Rotaries (Score:2)
A lot of cities uses rotaries instead to get rid of the traffic lights.
Then there are some morons that put traffic lights in the rotaries.
