Rotary two-way one-way three-dimensional road

technical field

The invention relates to a three-dimensional road, in particular to a precession type two-way one-way three-dimensional road.

Background technique

With the continuous increase of urban vehicles, urban road congestion is becoming more and more serious. The main cause of road congestion is due to the traffic lights at each intersection changing in turn and driving stopped. In order to effectively solve urban road congestion, the most common method is to set up overpasses at major arterial intersections. Straight vehicles can pass through the overpasses and continue to move forward. Under the overpasses, an underbridge passage from one side of the road to the other can be set up. . In this way, the number of traffic lights at intersections can be reduced, which in turn can effectively alleviate the congestion of urban roads.

Existing overpass bridges all set span-type overpass sections on the original one-way street. The overpass bridge of this structure can meet the smooth travel of straight-going and right-turning vehicles; As far as the vehicle going straight is concerned, it first needs to make a right turn, then cross a road to realize a left turn and then go straight, and then cross a road to realize a left-turn parking and turn left and then go straight in the opposite direction. When crossing the highway, it is necessary to wait for the traffic light to turn from red to green. Although it is close at hand, it may take several minutes to arrive. Therefore, people's waiting time is increased, and vehicles are no longer unimpeded. And for the place that does not set traffic light, then also need to detour longer road, increased the inconvenience of people's travel further.
