Interchange Crossroad with People Walking on Ground, Vehicles Traveling Above and Under Ground, and Only Vehicles on the Same Way Giving Way to One Another

Abstract

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.

1 . An interchange crossroad with people walking on ground, vehicles traveling above and under the ground, and only vehicles on a same road giving way to one another, characterized by achieving isolation by being layered, people and vehicle flows being unobstructed, no vehicle appearing on an entire ground level of the crossroad, off-road land being not occupied, amount of construction labor being moderate, and popularization for usage being convenient,
 wherein as a basic type, four layers are comprised which are an overpass, a mezzanine, a ground plane and an underpass from up to down, wherein the overpass layer allows vehicles traveling in a longitudinal direction to go straight and make a turn, and the underpass layer allows vehicles traveling in a transverse direction to go straight and make a turn, only vehicles on the same road give way to one another under traffic lights, and the overpass layer and the underpass layer are provided with lateral parking horizontal wing spans, with lengths of the lateral parking horizontal wing spans determined according to actual cases;   as a reduced and flexible type, the four layers are reduced to three layers, “only the vehicles on the same road giving way to one another” is changed to “only the vehicles giving way to one another”, the vehicles are centralized on one layer in such a manner that the vehicles travel on either the overpass or the underpass and all the vehicles are commanded by traffic lights, wherein if the underpass layer is selected for centralized usage, big steps can be arranged above main ramps of the underpass in four directions;   an entire crossroad zone of the ground plane layer has no vehicle and is used exclusively for citizens, an usable area is enlarged by the big steps above the main ramps of the underpass, and the mezzanine is used exclusively for bicycles.   
     
     
         2 . The interchange crossroad according to  claim 1 , wherein the overpass layer of the basic type comprises an overpass main ramp ( 4 ), a main road horizontal crossroad zone with an elevation and located at a top of the overpass, an overpass ramp ( 5 ) which allows a turning vehicle to go downhill and back to the ground, and two overpass lateral wing parking zones each having an arbitrary length, and the two overpass lateral wing parking zones are an overpass lateral wing parking zone ( 6 ) and an overpass lateral wing parking zone ( 7 ), respectively. 
     
     
         3 . The interchange crossroad according to  claim 1 , wherein the underpass layer of the basic type comprises an underpass main ramp ( 9 ), a main road horizontal crossroad zone with an elevation and located at a bottom of the underpass, an underpass ramp ( 10 ) which allows a turning vehicle to go uphill and back to the ground, and two underpass lateral wing parking zones each having an arbitrary length, and the two underpass lateral wing parking zones are an underpass lateral wing parking zone ( 11 ) and an underpass lateral wing parking zone ( 12 ), respectively. 
     
     
         4 . The interchange crossroad according to  claim 1 , wherein the crossroad zone of the ground plane layer comprises: two lower portions ( 13 ) under main ramps of the overpass and two higher portions ( 14 ) under the main ramps of the overpass, which are paved sequentially in both directions; two sets of big steps ( 16 ) above main ramps of the underpass in the basic type, with the two sets of big steps arranged opposite to each other in both directions; and a central intersection of the ground plane, with the central intersection being a core area ( 15 ) of a crossroad vacant lot. 
     
     
         5 . The interchange crossroad according to  claim 1 , wherein the mezzanine dedicated for bicycles is sandwiched between a core area ( 15 ) of a crossroad vacant lot and a main road horizontal crossroad zone with an elevation and located at a top of the overpass, and the mezzanine is attached with a bicycle ascent ( 17 ) and a bicycle descent ( 18 ). 
     
     
         6 . The interchange crossroad according to  claim 1 , wherein at the underpass or overpass of the reduced and flexible type, the vehicles from all directions intersect, and are supervised by traffic lights to give way to one another.
