Combination structure of four single bridges turning in same direction and ring-shaped groove lane at crossroad

Abstract

The invention relates to a combination structure of four single bridges turning in same direction and a ring-shaped groove lane at a crossroad and belongs to the traffic building facility combination structure with totally smooth direct movement and big turning at the crossroad. The bottom layer of the ring-shaped groove lane arranged at the crossroad is provided with four lane changing positions. The radian of an inlet ring point and an outlet ring point of each lane changing position is in the range of the radian corresponding to 0 to 90 degrees of an inclined angle of a center angle; one end of each single bridge turning in the same direction is respectively connected with the surface layer of a ground branch road, while the other end thereof is connected with the bottom layer of the ring-shaped groove lane; and the parts inside single bridge rings of the single bridges turning in the same direction have the same turning direction. The combination structure has the advantages of only using four single bridges turning in the same direction, four outer ring single rampways and one bottom layer of the ring-shaped groove lane, using fewest traffic building facilities and lowest cost, occupying smallest ground and space of the crossroad and realizing totally smooth direct movement and big turning without cross road occupation at the crossroad in a mode of meeting the existing traffic rules.

Description

technical field [0001] The present invention belongs to the traffic construction facilities for going straight and turning big turns [right-hand system left turn, left-hand system right turn] traffic construction facilities at the crossroads of arterial roads, in particular four single bridges and crossroads that turn in the same direction are used to sink into the ground Combined with the circular grooved lanes, the combined structure of the traffic building facilities that can go straight and turn big turns is completely unimpeded. Background technique [0002] At present, the traffic at level crossings of international and domestic urban arterial roads is very crowded and often blocked, which is a common problem in major cities all over the world. The reason is that two roads intersect at a level. At the intersection, the two roads overlap and become one road. Vehicles on the two roads can only share one road at the node, and half of the road resources are lost. It will ...

Problems solved by technology

Its disadvantages: First, there are two kinds of driving regulations on a cross road. Drivers must recognize the traffic signs painted on the ground every time they cross the cross road.

The second is that the road division specification of going straight from the inside to the outside of the ring --- turn left --- turn right is different from the existing road division specification of turning left --- go straight --- turn right, which makes it easy for drivers to drive away from the intersection. Before the mouth, according to the existing left-turn---go straight---right-turn road division standard driving, it is too late to see the straight line---left turn---right turn road division standard after approaching the overpass bridge of this invention changing lanes, causing congestion and accidents

In a word, the road division specification of going straight --- turning left --- turning right from the inside of the ring to the outside of the ring required by the overpass is different from the existing road division specification of turning left --- going straight --- turning right, so that the overpass It cannot be applied on roads with existing left-turn---go straight---right-turn road division regulations
