A distributed two-layer directed flyover is formed of fast vehicular driveways and multifunctional driveways. The fast vehicular driveways are of a two-layer directed type, and necessary 16 overpass points of the vehicular driveways are distributed at four surrounding directions and five central fast overpass areas of crossroads. The multifunctional driveways use a looped structure, and 32 overpass points of the driveways are averagely distributed at multifunctional overpass areas of the four surrounding directions. The flyover occupies a small area, and has high pass-through efficiency. |
