Embodiment Construction

[0028] Such as Figure 1 to Figure 4 Shown, a kind of overpass bridge of city road crossroads, comprises: overpass deck and road of four directions of crossing;

[0029] The road connected by the overpass deck in each direction is at least six lanes;

[0030] The inner side of the overpass surface in each direction has an inner ramp bridge 1 towards the center, and the outer side is an arc-shaped curved bridge 9;

[0031] The overpass deck in each direction also includes: an outer ramp bridge 5 positioned on the leftmost side and a guide lane bridge positioned on the right; at least three lanes of the guide lane bridge are respectively straight lanes from left to right 2. Left-turning lane 3, right-turning lane 4; the vehicle in the straight lane 2 goes straight to the inner ramp bridge 1 until the lower bridge reaches the opposite road 6, 7; the vehicle in the left-turning lane 3 travels on the overpass Turn left to the curved bend bridge 9 and then turn left to reach the o...

Abstract

An overpass at an urban road intersection comprises overpass surfaces and roads which are crossed in four directions. Roads connected with the overpass surface in each direction are at least six lanes; the inner side, facing the center, of the overpass surface in each direction is provided with an inner side ramp bridge, and the outer side of the overpass surface is provided with an arc-shaped curve bridge; the overpass surface in each direction further comprises an outer side ramp bridge located on the leftmost side and a guide lane bridge located on the right side; at least three lanes of the guide lane bridge are a straight lane, a left turning lane and a right turning lane in sequence from left to right; and a U-shaped curve bridge is arranged between the straight lane of the guide lane of the overpass surface in each direction and the outer side ramp bridge, so that straight vehicles can reach the outer side ramp bridge of the road on the same side through the U-shaped curve bridge to turn around. According to the invention, traffic lights are unobstructed in all directions, people and vehicles are shunted, hidden dangers of traffic accidents of people and vehicles are eliminated, and major traffic accidents are effectively prevented.

Description

【Technical field】 [0001] The invention belongs to the technical field of road traffic, and specifically refers to an overpass bridge at an urban road crossroad. 【Background technique】 [0002] With the continuous improvement of social economy and urban development level, the ownership of urban cars has increased rapidly, which has caused great congestion to road traffic, especially urban road traffic, especially the congestion at intersections in the city center. The congestion in these places not only delays people's travel and time, but also delays the tail gas emitted by cars waiting at intersections, which adds serious pollution to the city. Therefore very much need a kind of pedestrian and motor vehicle to be separated effectively, both help automobile to pass through the crossing fast, the overpass scheme that can make things convenient for the pedestrian's crossing to the greatest extent again simultaneously. [0003] Chinese utility model patent 200920136896.0 discl...
