A highway interchange facilitates the intersection of two or more highways or other roadways. A plurality of travel paths forming a major thoroughfare and a minor thoroughfare are connected together through a plurality of exits. For each travel path, a right turn exit and a left turn exit are provided, giving travelers the option of either continuing straight or transitioning from one thoroughfare to the other in either direction.

The present application relates to a synergistic dual-modes sustainable interchange. The interchange is mainly formed by accessible highways and intersecting roads, herein disposed with a plane intersection of traffic lights and crosswalks; under the schedule of dual modes of one-red and one-green, the plane intersection is connected to the connecting roads for entering and exiting the accessible highways or entering and exiting the accessible highways from the intersecting roads; the upstream and downstream accessible cut-through lanes are respectively disposed on both sides of the plane intersection by overpasses, and rejoin at the other end. The group of ramps for entering and exiting the accessible highways, their relevant connecting roads and the ring roads configured with error-corrected U-turn mechanism, are all disposed between the upstream and downstream portions of the highway.

An interchange crossroad with people walking on ground and vehicles traveling above and under the ground is provided. In a basic type, four layers are comprised which are an overpass, a mezzanine, a ground plane and an underpass from up to down, the overpass and underpass respectively allow vehicles traveling longitudinally and vehicles traveling transversely to go straight and make a turn, only vehicles on the same road give way to one another under traffic lights, and the overpass and underpass are provided with lateral parking horizontal wing spans of adjustable lengths. In a reduced and flexible type, the four layers are reduced to three layers, only vehicles giving way to one another is achieved, all the vehicles are centralized on either the overpass or the underpass and commanded by traffic lights. The entire crossroad zone of the ground plane layer has no vehicle and is used exclusively for citizens.

The present invention discloses a thoroughly smooth urban traffic system, which has a two-dimensional urban plane and a road with two main directions which are perpendicular or nearly perpendicular to each other. On an underground first layer, the road in the first main direction is occupied separately, and all automobiles, subways, trains and municipal corridors in this direction are roughly parallel without level crossing, and are smooth. On an underground second layer, the road in the second main direction is occupied separately, and all automobiles, subways, trains and municipal corridors in this direction are roughly parallel without level crossing, and are smooth. The underground layers can be provided with urban sufficient parking lots. An underground third layer is used for non-motor vehicle roads, parking and a large-scale reservoir. On a ground plane layer, only houses, plants, people, open-air bars, etc. are exposed in the sun, to establish a veritable urban park.

A spiral road junction system for connecting a plurality of highway spokes via a spiral road junction comprising adjacent-spoke connecting roads associated with each highway spoke, and a ring-road interchange traversing all the highway spokes. The ring-road interchange provides a continuous path from a slip road diverging from an entry highway spoke to an access road merging with an exit highway spoke.
