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

[0032] Example 1. Self-striding right-turning overpass at intersections with both ends located on the straight sideways of cars

[0033] There is a right-curved overpass 1 with a horizontal plane at both ends of the bridge deck and a 100-degree turn at both ends. The upper end 2 and lower end 5 of the right-curved overpass 1 are located at the intersection away from the crosswalk 8 and the right crosswalk 9 At 40 meters, make the right-curved overpass 1 cross the two pedestrian crossings 8 and 9 on the right of the car; the upper bridge end 2 of the right-curved overpass 1 is located on the straight side road 4 of the non-car lane 3; the right-curved overpass 1 The lower bridge end 5 is located on the right side road 6 on the right side of the upper bridge end 2. The bottom surface of the right-curved overpass 1 is located at the crosswalk 8 and the right crosswalk 9 with a height of 2 meters from the ground.

Embodiment 2

[0034] Example 2. A self-spanning right-turning overpass at an intersection on a non-car lane at both ends of the city center area has a layer of arched bridge deck with both ends connected to a horizontal plane, and a right-turning overpass 1 with 90 turns at both ends, starting to turn The length at both ends is 50 meters. The upper bridge end 2 and the lower bridge end 5 of the right-curved overpass 1 are located 40 meters away from the crosswalks 8, 9 at the intersection, so that the right-curved overpass 1 crosses the two pedestrian crossings 8 where the car turns right. And the right crosswalk 9; the upper bridge end 2 of the right-curved overpass 1 is located on the non-car lane 3; the lower bridge end 5 of the right-curved overpass 1 is located on the right side road 6 on the right side of the upper bridge end 2. The bottom surface of the right-curved overpass 1 is located at the crosswalk 8 and the right crosswalk 9 with a height of 2 meters from the ground.

Embodiment 3

[0038] Example 3. Self-striding right-turning overpass at intersections on non-car lanes at both ends of the city center

[0039] There is an arch-shaped right-curving overpass 1 with both ends of the bridge deck connected to a horizontal plane and a 60-degree turn at both ends. The length of the two ends at the beginning of the turn is 40 meters. The upper end 2 and the lower end 5 of the right-curving overpass 1 are located at the intersection The intersection is 60 meters away from the crosswalk 8 and the right crosswalk 9, so that the right-turning overpass 1 crosses the two crosswalks 8 and 9 where the car turns right; the upper bridge end 2 of the right-turning overpass 1 is located on the non-car road 3; The lower bridge end 5 of the curved overpass 1 is located on the right non-car lane 7 on the right side of the upper bridge end 2. The bottom surface of the right-curved overpass 1 is located at the crosswalk 8 and the right crosswalk 9 with a height of 3 meters from the g...

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, and in particular relates to a right-turn overpass at intersections in existing road traffic regulations in China. Background technique [0002] At present, there are only two ways to deal with the right-turning of cars at level crossings on international and domestic urban roads: one is to allow cars to turn right. People think that turning right is the easiest way for a car to turn right, because it does not conflict with cars in any other direction, so it can travel without restrictions, even at a red light, but at this time, the car turns right. There was a serious conflict with pedestrians crossing the street. Because pedestrians and right-turning cars are allowed to pass at the same time, a situation of mixed traffic is caused. Cars complain that pedestrians will affect the speed of traffic; pedestrians are afraid that right-turning cars will threaten their safety and lives, and car acci...
