Queue Jumper Intersection
Can local roads act like highways? With this engineering innovation called a "queue jumper", through traffic on local roads can pass over (or under) local traffic turning onto cross streets--all the convenience of a highway without the expense!
Moving traffic in congested areas is difficult under any circumstances, and too often we use the wrong engineering technology to address an important problem. Rather than building horizontally, we need to build vertically, channeling traffic based on function and trip purpose like this 21st century intersection.
