<p>A traffic flow distribution interchange that provides non-stop and streamlined flow of freeway traffic along two crossing routes, and that occupies a relatively small amount of land area. The freeway interchange comprises a non-elevated route and an elevated crossing route which passes over the non-elevated route. Each route is substantially straight and provides traffic flow in two directions. The elevated and non-elevated routes are linked directly by four traffic flow paths along which vehicles can make right-hand turns from one route to the other. The elevated and non-elevated routes are linked indirectly by four additional traffic flow paths comprising configured ramps along which vehicles can make left-hand turns from one route to the other. These configured ramps pass under the elevated route and cross no other traffic flow path, providing unimpeded traffic flow.</p> |
