Problems solved by technology

[0006] The purpose of the present invention is to solve the problems that the overpass system of the intersection with the existing structure has a large footprint, high investment, and is not suitable for urban roads, and to provide a method that can be transformed on the basis of existing urban roads. With small footprint and low investment, it is suitable for the interchange system at the intersection of urban roads
[0007] Another object of the present invention is to provide a turn-around interchangeable crossroad system in order to solve the problem that the vehicle existing in the interchange bridge system of the existing structure cannot turn around

Embodiment 1

[0023] Embodiment 1: a kind of quick and smooth urban road intersection overpass system of the present invention, as figure 1 As shown, near the intersection, the east-west lane and the north-south lane are two-way six-lane lanes, and there are sidewalks 6 on both sides of the lanes, and the lane in the middle of the road in the east-west lane and the north-south lane is a large vehicle lane 2 , the large vehicle lane is two lanes, and the large vehicle lane is specially used for the passage of large vehicles such as buses and large trucks, while the left and right sides of the large vehicle lane are small vehicle lanes 1, and the small vehicle lane is specially used for cars, vans For the passage of small vehicles such as small vehicles, the small vehicle lanes are two lanes on the entering side and the leaving side, and the outermost lane is used for vehicles turning right, which is right-turning lane 11; the other lane is used for vehicles going straight, Turn left and make...

Embodiment 2

[0025] Embodiment 2: a kind of quick and smooth urban road intersection overpass system of the present embodiment, as figure 2 As shown, the basic road structure is the same as in Embodiment 1, and also includes a large vehicle lane 2, a small vehicle lane 1 and an overpass 3 arranged on the large vehicle lane, and the traffic mode of a large vehicle is also the same as in Embodiment 1, the difference The overpass adopts a reinforced concrete structure, and the pedestrian overpass is replaced by safety island 5. There are eight safety islands, which are respectively arranged on the small vehicle lanes of the east-west direction lane and the north-south direction lane, which are close to the overpass bridge and away from the road intersection. At the same time, in order to facilitate small For the passage of vehicles, the small car lanes are respectively provided with connected bay-type shunt lanes 7 near the overpass. Affects the driving of small vehicles. Further, in order ...

Abstract

The invention discloses a rapid unblocked urban road intersection interchange system, which comprises a bidirectional multilane east-west lane, a bidirectional multilane south-north lane and a sidewalk. Near an intersection, the lanes at the outer sides of the east-west lane and the south-north lane are small vehicle lanes; the lanes in the middle of the road are large vehicle lanes; the large vehicle lanes of the east-west lane and the south-north lane are respectively provided with a flyover which is codirectional with the lanes at two sides of the intersection; large vehicle lane traffic lights for controlling the running of the vehicles on the large vehicle lanes are arranged at the intersection; and safety islands and harbor type diversion lanes are arranged on the small vehicle lanes to ensure the traffic safety of pedestrians. In the invention, through the diversion between large vehicles and small vehicles, the traffic capacity of the intersection is effectively improved; and at the same time, the system is simple in overall structure, small in floor space, low in construction cost and suitable for the reconstruction of the existing roads.

Description

[0001] technical field [0002] The invention relates to a three-dimensional intersection structure of roads, in particular to an overpass system of urban road intersections with simple structure and less land occupation. [0003] Background technique [0004] With the rapid development of economic construction and the continuous improvement of people's living standards, the number of cars, especially the number of private cars, is increasing rapidly, making urban roads more and more congested, especially at intersections. more serious. In order to solve the vehicle congestion problem at crossroads, and then improve the driving speed of the whole road section, people have come up with the overpass system of various road grade intersections. Although the existing overpass system can solve the problem of cross-interference of vehicles, it usually has the problems of complex structure, large footprint and inconvenient turning of vehicles. Therefore, it is not suitable for mos...
