Overpass

Abstract

An overpass, including: a main road, an auxiliary road, a turntable, a cross-shaped viaduct, a sidewalk, an elevated bicycle lane, an elevated bicycle parking layer, and a first lower level floor. The main road includes: a first lower level main connecting lane. The auxiliary road includes: a first lower level auxiliary connecting lane. The turntable includes: a plurality of bus stops, taxi docking stations, and outer pedestrian ladders. The cross-shaped viaduct includes: a dual-line bridge and a single-line bridge. The first lower level floor includes a first lower level parking lot. The main road and the auxiliary road cross intersect at the turntable. The cross-shaped viaduct crosses above the turntable and is connected to the main road and the auxiliary road. The dual-line bridge is connected to the main road and the single-line bridge is connected to the auxiliary road.

 the taxi docking stations and the outer pedestrian ladders connected to the first lower level floor are disposed at an outer side of the turntable; and 
 entrances of the outer pedestrian ladders are connected to the taxi docking stations on the ground, respectively. 
 
     
     
         2 . The overpass of  claim 1 , wherein both the main road and the auxiliary road are provided with a back-turn left-turn dual-purpose lane, a straight lane, a bus lane, and a right-turn lane inside out. 
     
     
         3 . The overpass of  claim 1 , wherein
 four bus stops are disposed at the central part of the turntable corresponding to each road intersection;   the bicycle parking layer is provided with a pedestrian escalator downwardly connected to the bus stops; and   a central part of the bus stops is provided with a pedestrian ladder connected to the first lower level floor.   
     
     
         4 . The overpass of  claim 1 , wherein the turntable is provided with a road surface marking indicating a clockwise direction and a road surface marking indicating a counter clockwise direction. 
     
     
         5 . The overpass of  claim 1 , wherein
 the main road comprises a unidirectional parking main approach connecting the main road to the first lower level floor; and   the auxiliary road comprises a unidirectional parking auxiliary approach connecting the auxiliary road to the first lower level parking lot.   
     
     
         6 . The overpass of  claim 1 , wherein
 the main road is provided with a combination of traffic lights capable of changing a traffic direction from the main road to the dual-line bridge; and   the combination of traffic lights is disposed close to an entrance of the unidirectional parking main approach.   
     
     
         7 . The overpass of  claim 5 , wherein
 a second lower level floor is disposed beneath the first lower level floor;   the second lower level floor comprises a bidirectional vehicle tunnel disposed beneath the auxiliary road for connecting the second lower level floor to the auxiliary road;   the first lower level floor comprises a second lower level connecting lane and a second lower level pedestrian escalator connected to the second lower level floor;   two second lower level metro lines are disposed at two sides of the bidirectional vehicle tunnel, respectively; and   the second lower level floor is provided with a second lower level parking lot functioning as a temporary parking lot before metro construction.   
     
     
         8 . The overpass of  claim 7 , wherein
 a third lower level floor is disposed beneath the second lower level floor;   the third lower level floor is provided with a third lower level connecting lane and a third pedestrian escalator connected to the second lower level floor;   four metro lines are disposed at the third lower level floor; and   the third lower level floor is provided with a third lower level parking lot functioning as a temporary parking lot before metro construction.
