Description

Crossroad overpass and road network

Technical field

The present invention relates to the field of road traffic, and in particular to a crossroad overpass and a road network. Background technique

At present, in road traffic, intersections generally consist of longitudinal roads and horizontal roads. The most common is that the longitudinal and lateral roads intersect each other on the same plane, as shown in Figure 1. The traffic flow of such intersections can only be scheduled by means of traffic lights. First, the traffic on the vertical or horizontal roads is stopped, and the traffic on the roads in the other direction can be realized. When the traffic volume through such intersections is large, the scheme of alternately stopping and passing the longitudinal and lateral roads often causes the vehicles to gather and congest, which brings inconvenience to the traffic flow. At this intersection, when the vehicle needs to make a left turn, since the left-turning vehicle needs to traverse the entire traveling area of the opposite traffic, it is possible to drive into the lane to the left side, and the left turn of the intersection is small. The left turn is narrow, and the left-turning vehicle can easily collide with the crowded traffic that is coming in, causing a traffic accident.

In the prior art, in order to solve the problem of traffic congestion at the intersection, a longitudinal bridge structure is set on the basis of the original intersection, so that the longitudinal traffic flows over the horizontal traffic, thereby avoiding the longitudinal traffic and the horizontal traffic interfering with each other, however Such a design in the prior art would result in a failure to allow longitudinal traffic to turn at an intersection.

In order to avoid the mutual interference of the traffic flow, a roundabout type crossroad is designed in the prior art. As shown in Fig. 2, an "island" is arranged at the intersection of the road, and a circular road is arranged around the "island", thereby being Named "Circle Island". When the longitudinal and lateral roads are brought together at the roundabout intersection, turn all the way to the right and turn counterclockwise along the circular road. When you reach the road junction you want to transfer, turn right and enter the road. At this roundabout intersection, all vehicles can only make a right turn and can turn to the left side of the road by turning right and three-quarters of a circle, thus avoiding vehicle collisions and traffic accidents caused by left turns. However, straight-through vehicles will have to slow down, turn and cycle through this roundabout intersection, which slows down the speed of straight traffic on a vertical or horizontal road, and turns right and rings three-quarters of a circle. Instead of direct left turn, it not only slows down the traffic speed, but also effectively alleviates the problem of traffic concentration and congestion.

In order to avoid traffic congestion caused by low traffic speed, CN202559203U discloses a cross-shaped overpass, as shown in Fig. 3, including a cross-shaped straight lane of the upper and lower layers, and two downward curved ramps. The two downward curved ramps respectively start from the upper right lane crossing the intersection of the cross, and are bent downward to extend to the lower right lane adjacent to the upper right lane to realize the left lane driving. The turn also includes two left-turning lanes, the two left-turning lanes respectively starting from the lower-level right lane, passing through the lower-level lane through the tunnel, and connecting to the upper right lane through the ascending ramp to the ground, thereby realizing the lower lane Turn left on the train. In the scheme, the left and lower lanes of the vehicle will not cross the driving route of the straight-through vehicle when turning left, which solves the problem that the left turn of the vehicle is inconvenient and prone to accidents, but the upper and lower layers, the outward expansion, and the three-dimensional surround The complex structure will occupy a large plane area and a three-dimensional space, which is not only expensive, but also greatly increases the space cost of highway planning for a crowded city. Especially for areas with dense buildings in the city, the installation of such overpasses at the existing intersections will be greatly restricted. For example, the roadside buildings are relatively close to the road, so that no such overpasses are left. The necessary space. In addition, Since the lane for the turning of the vehicle is of an arc type design, the vehicle needs to be decelerated after being transferred from the straight lane to the arc lane, and the speed can be increased after re-entering the straight lane and regaining a higher speed; however, The arc-shaped lane is long and requires a long period of low-speed driving, which causes traffic jams due to slow driving speed.

Therefore, it is necessary to propose a suitable intersection design to adapt to the development of urban roads. Summary of the invention

The technical problem to be solved by the present invention is that the intersection design in the prior art cannot simultaneously solve the problem that the traveling speed is low, the collision is easy when the vehicle turns, and the design structure is complicated to occupy a large space; thus, a high driving can be realized.

The advantages of the crossover overpass and the road network provided by the present invention are:

(1) The crossroad overpass of the present invention is provided by a bridge road including a longitudinal road, a horizontal road, a vertical road, a horizontal road, and a bridge road including a longitudinal road, a horizontal road, a vertical road, and a horizontal road. The longitudinal traffic flow mainly passes through the bridge road, and the horizontal traffic flow mainly passes through the bridge under the road. The longitudinal traffic and the horizontal traffic do not need to alternately stop and pass, thus effectively dividing the longitudinal traffic and the horizontal traffic, even if there is no traffic light for traffic command and dispatch. In the case of traffic flow, the traffic can also pass smoothly, so that the traffic at the intersection is orderly, avoiding the accumulation and congestion of the traffic flow; compared to the prior art roundabout intersection and the overpass with curved ramp, the crossover overpass in the present invention The straight traffic flow on the bridge road and the bridge road does not need to be decelerated, turned and looped, so as not to adversely affect the traveling speed of the straight traffic flow; compared with the overpass of Fig. 3, the road junction turning section of the invention is short. The road used for turning is wider because it can make the vehicle turn Short time, therefore, the vehicle can travel speed immediately after the intersection turn. However, in Figure 3, the section of the overpass is longer, the section for turning is smaller, and the turning range is large. Therefore, the vehicle travels at a low speed for a long time during cornering, which may affect the speed of other vehicles, which may occur. traffic congestion. In addition, the interference of the turning traffic of the crossover overpass of the present invention is significantly reduced, and the collision of the vehicle is not easy, thereby effectively reducing the incidence of traffic accidents; and the plane area and the three-dimensional space occupied by the simple structure are smaller, compared with In the prior art, various three-dimensional multi-layered overpasses not only save engineering cost, but also greatly save the area and space cost of highway planning.

Accordingly, the present invention provides a crossover overpass capable of achieving a higher traveling speed, a low probability of collision of a vehicle during cornering, and a simple design structure to save floor space.

(2) The crossover overpass of the present invention, the longitudinal two-way, the longitudinal four-way, the transverse two-way, and the transverse four-way are two-way roads, having two opposite traffic directions, including at least two lanes; a longitudinal one, a longitudinal three-way, Both Hengyi Road and Hengsan Road are one-way roads with only one traffic direction and at least one lane. Longitudinal Road, Longitudinal Road, Henger Road, Hengsi Road, and the Longitudinal Road, Longitudinal Road, Hengyi Road, and Hengsan Road, which are used as the main roads, are designed to effectively utilize the bridge. Surface and pavement space.

(3) The crossover overpass of the present invention, the horizontal one road and the third horizontal road only have a traffic flow direction that allows the vehicle to turn from the longitudinal road section into the horizontal road section; the longitudinal one road and the vertical three road only have one that allows the vehicle to turn from the horizontal road section into the longitudinal road section. The direction of traffic flow, thus on the road mainly for the longitudinal traffic There are roads for the left turn of the vehicle and roads for the right turn of the vehicle, namely Hengyi Road and Hengsan Road. There is also a left turn road connecting the longitudinal roads under the bridge for the horizontal traffic. With the right turn, that is, the longitudinal one and the third three.

Take the vehicle to the right according to the traffic rules. When the vehicle turns right (for example, when turning right from the right lane on the right side of the second road to the horizontal one), the vehicle making the right turn will not be affected by other vehicles; the left turn of the vehicle When (for example, when turning from the forward lane on the right side of the vertical road to the third lane), it will only intersect with a part of the traffic flow on the reverse lane on the left side, compared with the conventional crossroads of the prior art. The traffic of the crossroad overpass of the invention that turns left from the longitudinal road into the transverse road is not interfered by the vehicle from the transverse road, and the traffic that turns left from the transverse road into the longitudinal road is not interfered by the vehicle from the longitudinal road, thereby It is not easy for a vehicle collision to occur, which effectively reduces the incidence of traffic accidents.

Preferably, the vertical five roads and the vertical six roads are one-way roads, and have only one traffic flow direction, and at least one lane. Taking the vehicle to the right according to the traffic rules, the straight traffic on the vertical 2nd road can be directly driven into the vertical 6th road, thereby further reducing the straight traffic flow on the vertical road and the left turn from the opposite vertical road. The overlapping areas of the left-turn traffic flowing into Hengyi Road further reduce the probability of traffic accidents caused by vehicle collisions; the straight traffic on the vertical four-way road can directly go straight into the vertical five-way, thus further reducing the vertical four. The overlapping area of the straight traffic on the road and the left turn from the opposite vertical road to the left turn of the third road further reduce the probability of traffic accidents caused by vehicle collisions. In the case where the vehicle should be driven to the left according to the traffic rules, it is similar to the above analysis and will not be described here.

(6) Similar to the above analysis, in the case where the bridge overpass of the crossroad overpass of the present invention further includes a vertical five-way and a vertical six-way, the bridge deck at the intersection may also include an extended deck area. In the case that the vehicle should travel to the right according to the traffic rules, the junction of the vertical five road and the horizontal three road has a first extended bridge deck area, and the junction of the longitudinal six road and the horizontal one road has a second extended bridge deck area, by setting the above The extended bridge deck area makes the left-turning vehicle more convenient, further reducing the probability of traffic accidents; in the case that the vehicle should be driven to the left according to traffic rules, the connection between the vertical five road and the horizontal one road has the first expansion. In the bridge deck area, the junction of the longitudinal six-way and the horizontal three-way has a second extended deck area, and by providing the above-mentioned extended deck area, the right-turning vehicle is more convenient to travel, further reducing The probability of occurrence of a traffic accident.

(7) Preferably, the bridge underpass of the crossover overpass of the present invention further includes Hengwu Road and Hengliu Road, wherein Hengwu Road and Henger Road are respectively located on opposite sides of Hengyi Road, and Hengliu Road and Hengsi Road are respectively located. The opposite sides of the horizontal three roads. Preferably, Hengwu Road and Hengliu Road are all one-way roads, and only have one traffic direction, and at least one lane. Similar to the above analysis, in the case that the vehicle should be driven to the right according to the traffic rules, the straight traffic that is traveling forward on the horizontal two road can directly go straight into the horizontal six road, thereby further reducing the straight traffic flow on the horizontal two road. The overlapping area of the left-turning traffic flowing from the opposite side of the four-way road to the third-way road further reduces the probability of traffic accidents caused by vehicle collisions; the straight traffic that is traveling forward on the horizontal four-way can directly go straight into the horizontal The five-way road further reduces the overlapping area of the straight traffic flow on the horizontal four-way forward and the left-turn traffic flow from the opposite horizontal two-way turn to the vertical one, further reducing the probability of traffic accidents caused by vehicle collision. In the case where the vehicle should travel to the left according to the traffic rules, it is similar to the above analysis and will not be described here.

(8) The crossroad intersection of the road network provided by the present invention has the above-mentioned crossroad overpass, and the main road with a large traffic volume of the road network can be used as the longitudinal road of the crossroad overpass, and is passed through the bridge road, thereby making the road through the bridge The straight traffic on the horizontal branch road and the traffic flow on the main road are separated from each other by the main road traffic. The main road and the branch road traffic do not directly intersect, thus achieving the effect of significantly reducing the congestion of the main road vehicles and improving the circulation of the main road vehicles. The smoothness of the road network also reduces the overlapping area of the straight traffic flow and the turning traffic flow, and reduces the probability of a traffic accident caused by the vehicle collision; further, the road network occupied by the present invention generally occupies a plane The area and the three-dimensional space are small, which not only saves the project cost, but also greatly saves the area and space cost of the traffic road network design and construction.
