Problems solved by technology

Pedestrians crossing the street and cars turning right are allowed to pass at the same time, resulting in a mixed traffic situation. Cars complain that pedestrians crossing the street affect the driving speed; pedestrians crossing the street are afraid that cars turning right will threaten their safety and lives, and accidents may happen at any time
The second is to restrict right-curving cars, which can only drive when the light is green, so that pedestrians on the road are safer, but right-curving cars waste time and gasoline waiting for red lights, and also waste some road resources. After turning the corner, there is also a conflict with another pedestrian crossing the street

Embodiment 1

[0034] Embodiment 1, self-spanning right-turning overpass at an intersection where both ends are located on the straight sidewalk of automobiles

[0035] There is a right-curved overpass 1 in which both ends of the bridge deck are connected to the horizontal plane, and the two ends are 100-degree turns. The upper bridge end 2 and the lower bridge end 5 of the right-curved overpass 1 are located at the intersection away from the pedestrian crosswalk 8 and the right pedestrian crosswalk 9. 40 meters position, make its right-curving overpass 1 cross two crosswalks 8,9 of automobile right-curving; The upper bridge end 2 of right-curving overpass 1 is positioned on the automobile straight sidewalk 4 of non-car lane 3; Right-curving overpass 1 The lower bridge end 5 is positioned on the right side road car straight side road 6 on the bridge end 2 right sides. Right bend overpass 1 bottom surface is positioned at pedestrian crosswalk 8 and the height above the ground of right pedestr...

Embodiment 2

[0036] Embodiment 2, the two ends in the city center area are positioned at the intersection on non-motorway road crossing self-spanning type turn overpass bridge

[0037] There is a right-curved overpass 1 in which the two ends of the bridge deck are connected to the horizontal plane, and the two ends are 90-degree turns. The length of the two ends at the beginning of the turn is 50 meters. The position of 40 meters away from pedestrian crossing 8,9 makes its right-curving overpass 1 cross two pedestrian crossings 8 and right side pedestrian crossing 9 of automobile right-curving; The lower bridge end 5 of overpass bridge 1 is positioned at the right side road car straight side road 6 of upper bridge end 2 right sides. Right bend overpass 1 bottom surface is positioned at pedestrian crosswalk 8 and the height above the ground of right side pedestrian crosswalk 9 positions is 2 meters.

[0038] The middle part of the turning part of the present embodiment overpass is provided...

Embodiment 3

[0041] Embodiment 3, the intersection self-span type right-turning overpass that is positioned at the intersection on the non-car lane at the two ends of the city center

[0042] There is a right-curved overpass 1 in which the two ends of the bridge deck are connected to the horizontal plane, and the two ends are turned at 60 degrees. The length of the two ends at the beginning of the turn is 40 meters. Crossing is far away from the 60 meter position of crosswalk 8 and right side crosswalk 9, makes its right-curved overpass 1 cross two pedestrian crosswalks 8,9 of automobile right-curve; The lower bridge end 5 of curved overpass 1 is positioned on the right non-motorway 7 on the upper bridge end 2 right sides. Right bend overpass 1 bottom surface is positioned at pedestrian crosswalk 8 and the height above the ground of right side pedestrian crosswalk 9 positions is 3 meters.

[0043] The middle part of the turning part of the present embodiment overpass is provided with upri...

Abstract

The invention relates to a self crossing type right turning viaduct in crossing, suitable for turning right at crossing under Chinese current road traffic rules, which comprises the arcs on two end of the first viaduct floor jointed to the horizontal plane and a right bent viaduct with two bends of 60-120 degrees on both ends; the entry end and the exit end of the right turning viaduct are positioned at the crossing far from the crosswalk and the right side crosswalk; the entry end is positioned on the motor straight going side of the non-mechanical vehicle lane or on the mechanical vehicle lane; the exit end is positioned on motor straight going side on the right side road of the entry end or on the right non-mechanical vehicle lane; and the function formula of the obliquity degree number Y of the oblique bridge pier, the turning angle degree number X, and the turning length L is: Y=90-K[(180-X) / L]. The invention can realize automobile unblocked right turning on straight going side lane, that is, no road occupation conflict with the pedestrians on crosswalk with turning right. in addition, the right turning viaduct has low requirement for height, low building cost and less influence to the normal traffic at crossing wile constructing.

Description

technical field [0001] The invention belongs to the technical field of road overpasses, in particular to a right-turn overpass at a crossroad intersection according to the existing road traffic regulations in China. Background technique [0002] At present, there are only two kinds of processing methods for turning right-handed cars at level-crossing intersections of international and domestic urban roads: the one is to let the right-handed cars go. People think that it is easiest for a car to turn right, because it does not conflict with any other car in the other direction, so it can drive without restriction, even at a red light, but at this moment, the car turning right Serious conflicts occurred with pedestrians crossing the street in this limbo. Pedestrians crossing the street and cars turning right are allowed to pass at the same time, resulting in mixed traffic of people and vehicles. Cars complain that pedestrians crossing the street affect the driving speed; The ...
