  However, in the prior art, the first road (elevated road) or the second road (underpass) is widened at the ground level, and a side path (widening portion) is provided for entering a rotary structure installed at the ground level. Therefore, there has been a problem that the overall scale of the multi-layered cross structure becomes large. In particular, in order to build a large-scale multi-layered crossing structure, a large construction site is required, so in areas such as urban areas where a transportation network has already been formed, the construction cost including land acquisition is high. There was a problem that it would be very expensive.

  The problem to be solved by the present invention is to provide a multi-layered intersection structure that can reduce the construction cost.

The above-mentioned problem is solved by connecting through the network.

  According to the present invention, the widening portion is provided by separately providing the first road and the second road on which the vehicle passing through the intersection structure travels and the third road and the fourth road on which the vehicle passing through the rotary structure travels. Without having to provide a multi-layered crossing structure that can enter and advance into the rotary structure. As a result, the scale of the multi-layered crossing structure can be further reduced, and the construction cost of the multi-layered crossing structure can be reduced. it can.

Similarly, the first ordinary road 10 intersects the third ordinary road 50 of the third road 300 extending in the X-axis direction in the intersection structure 1b. As a result, the vehicle traveling on the lanes 10 ₁ and 10 ₂ of the first ordinary road 10 toward the crossing structure 1b can go straight in the crossing structure 1b and can turn right and left in the crossing structure 1b.

  The second road 200 that intersects the first road 100 at the intersecting structure 1 a is composed of two types of roads, that is, the second ordinary road 30 and the second specific road 40. The second road 200 extends in the X-axis direction, and is the same as the first road 100 except that the number of lanes of the second ordinary road 30 is smaller than the number of lanes of the first ordinary road 10. The third road 300 that intersects the first road 100 at the intersection structure 1b is composed of two types of roads, that is, the third ordinary road 50 and the third specific road 60, and is the same as the second road. In FIG. 1, similarly to the first specific road 20, the second specific road 40 and the third specific road 60 are also indicated by hatching.

As described above, in the intersection structure 1a, vehicles traveling on the lanes 10 ₁ and 10 ₂ of the first ordinary road 10 and vehicles traveling on the lanes 30 ₁ and 30 ₂ of the second ordinary road 30 are in the intersection structure 1a. It is possible to go straight and turn left and right. Therefore, traffic lights 90a to 90d are installed in order to ensure safer traffic and smoother traffic. Similarly, also in the intersection structure 1b, vehicles traveling on the lanes 10 ₁ and 10 ₂ of the first ordinary road 10 and vehicles traveling on the lanes 50 ₁ and 50 ₂ of the third ordinary road 50 go straight in the intersection structure 1b. Since it is possible to turn left and right, traffic lights 90a to 90d are installed. In FIG. 1, vehicles passing through the first ordinary road 10, the second ordinary road 30, and the intersection structure 1a are shown in white.

On the other hand, lane ₂₀ 1, 20 ₂ constituting a first specific road 20 of the first road 100 is sandwiched between the lane ₁₀ 1, 10 ₂ of the first ordinary roads 10, as shown in FIG. 2, cross structure It has entered the basement from around 1a. Here, FIG. 2 is an enlarged perspective view showing a portion II of FIG. 1 (near the intersecting structure 1a of the first road 100). As shown in FIG. 2, lane 20 ₂ of the first specific road 20 is inclined to become lower toward the crossing structure 1a, a rotary inlet and outlet ports 80a, lane 10 ₂ of the first ordinary road 10 underground Lurking in. Similarly, lanes 20 ₁ of the first specific road 20 also is inclined to become lower toward the crossing structure 1a, a rotary entrance 70a, which is sunk into the lane 10 ₁ of the underground first ordinary road 10 . Although not illustrated, the same applies to the vicinity of the intersection structure 2b, and the lanes 40 ₁ and 40 ₂ constituting the second specific road 40 of the second road 200 and the third specific road of the third road 300 are also shown. The lanes 60 ₁ and 60 ₂ constituting the vehicle 60 are also submerged underground in the vicinity of the intersecting structures 1a and 1b. Then, lane ₂₀ 1, 20 ₂ of the first specific road 20, lane ₆₀ 1, 60 ₂ lane ₄₀ 1, 40 _2, and the third specific road 60 of the second specific road 40, as described later, it slipped In the basement, it is connected to the rotary structures 2a and 2b installed in the basement. In FIG. 1, vehicles passing through the first specific road 20 and the second specific road 40 are shown in black.

  Here, FIG. 3 is a diagram showing a positional relationship between the intersecting structures 1a and 1b installed at the ground level and the rotary structures 2a and 2b installed in the basement. In FIG. 3, the rotary structures 2 a and 2 b installed underground are indicated by broken lines, and the rotary structures 2 a and 2 b installed underground are superimposed on the intersecting structures 1 a and 1 b illustrated in FIG. 1. . Further, in FIG. 3, as in FIG. 1, the first specific road 20, the second specific road 40, and the third specific road 60 are indicated by hatching, and the first normal road 10 and the second normal road 30, vehicles passing through the intersection structure 1a are painted in white, and vehicles traveling through the first specific road 20, the second specific road 40, and the rotary structure 2a are painted in black. In the present embodiment, as shown in FIG. 3, the rotary structures 2a and 2b are installed so as to be positioned directly below the intersecting structures 1a and 1b, respectively.

  Moreover, FIG. 4 is a figure for demonstrating rotary structure 2a, 2b installed in the basement. 4A shows the rotary structures 2a and 2b installed underground, the first specific road 20 and the second specific road installed at the ground level, among the road structures having the multilayered intersection structure shown in FIG. Only 40 and the third specific road 60 are shown. FIG. 4B schematically shows a cross section taken along line BB in FIG. In FIG. 4, as in FIG. 1, the first specific road 20, the second specific road 40, and the third specific road 60 are indicated by hatching, and the first specific road 20, the second specific road 40 and the vehicle passing through the rotary structure 2a are shown in black.

  As shown in FIG. 4A, the rotary structures 2a and 2b installed in the basement have an annular shape, and the vehicle can go around the annular rotary structures 2a and 2b. ing.

The rotary structures 2a and 2b are one-way. For example, as shown in FIG. 4A, the rotary structures 2a and 2b according to the present embodiment are one-way in a clockwise direction when viewed from the positive direction of the Z axis. Therefore, for example, a vehicle that has entered from the lane 20 ₁ of the first specific road 20 through the rotary inlets 70a in the rotary structure 2a is a clockwise when the inside of rotary structure 2a, as viewed from the Z-axis positive direction by 90 ° circumferential direction, it is adapted to be able to advance from the rotary inlet and outlet ports 80b in lane 40 ₁ of the second specific road 40, likewise, by circulating in a rotary structure 2a, a rotary Susumu outlet 80c, 80d, the first specific road 20 ₁ from 80a, the second specific road 40 _2, thereby making it possible to advance the first respectively to a specific road 20 _2. In addition, since the rotary structures 2a and 2b are one-way streets, the traffic lights are not installed in the rotary structures 2a and 2b, unlike the cross structures 1a and 1b that can go straight and turn left and right.

In the present embodiment, as shown in FIG. 4 (A), vehicle, enters from the lane 20 ₁ of the first specific road 20 through the rotary inlets 70a, a rotary structure 2a that is installed underground, in 2b together and is capable of a rotary structure 2a installed underground, through a rotary inlet and outlet ports 80a from 2b, so that it can advance to the lane 20 ₂ of the first specific road 20 Yes. Further, as shown in FIG. 4 (B), lane 20 ₁ of the second specific road 20 is placed on the ground level, while the rotary structure 2a, 2b are installed underground. Thus, an inclined surface 71a that decreases from the rotary entrance 70a toward the rotary structures 2a and 2b and an inclined surface 81c that increases from the rotary structures 2a and 2b toward the rotary entrance 80c are formed. Therefore, the vehicle from the lane 20 ₁ of the first specific road 20 through the rotary inlets 70a, when entering a rotary structure 2a, the 2b, the vehicle becomes lower toward the rotary structure 2a Rotary inlets 70a It will enter the rotary structure 2a installed below the inclined surface 71a. Similarly, rotary entrance 70b, 70c, through 70d, vehicle, lane 40 ₂ of the second specific road 40, lane 20 ₂ of the first specific road 20, rotary structure from the lane 60 ₂ of the third specific road 60 2a and 2b can be respectively entered, and the rotary structures 2a and 2b can be used to enter the lane 40 ₁ of the second specific road 40 and the first specific road 20 via the rotary exits 80b, 80c and 80d. The vehicle can advance to the lane 20 ₁ and the lane 60 ₁ of the third specific road 60, respectively.

Thus, in the present embodiment, the thereby making it possible to advance from the rotary structure 2a in lane 20 ₂ of the first specific road 20, enters from the lane 20 ₂ of the first specific road 20 to the rotary structure 2b Can be done. That is, in this embodiment, through a lane 20 ₂ of the first specific road 20, so that it can travel from the rotary structure 2a Rotary structure 2b. Similarly, in this embodiment, through a lane 20 ₁ of the first specific road 20, so that it can travel from the rotary structure 2b Rotary structure 2a. Thus, in this embodiment, the rotary structure 2a is the lane ₂₀ 1, 20 ₂ of the first specific road 20, and is connected to the adjacent rotary structure 2b. Although not shown in FIG. 4A, when there are other rotary structures adjacent to the rotary structures 2a and 2b in the X-axis direction or the Y-axis direction, the rotary structures 2a and 2b are the first specific roads. lane ₂₀ 1, 20 ₂ 20, the lane ₆₀ 1, 60 ₂ lane ₄₀ 1, 40 ₂ or the third specific road 60, the second specific road 40, also connected to the other adjacent rotary structure.

  FIG. 5 is a schematic diagram showing a cross section of the multilayer cross structure of the present invention. As shown in FIG. 5, the road surface portion 21 of the rotary structure 2 is inclined in the road width direction so as to become lower toward the center of the annular rotary structure 2. Thereby, the influence of the centrifugal force applied to the vehicle orbiting the rotary structure 2 can be reduced, and the turning speed of the vehicle orbiting the rotary structure 2 can be improved. Moreover, the rotary structure 2 has the drainage groove | channel 22 for discharging | emitting the rainwater which flowed in the underground rotary structure 2 as shown in FIG. As a result, rainwater that has flowed into the rotary structure 2 is guided to the drainage groove 22 by the inclination of the road surface portion 21 and is discharged from the drainage groove 22. As a result, in the rotary structure 2, the drainage of the road surface portion 21 is improved, and it is possible to effectively prevent the vehicle that goes around the annular rotary structure 2 from slipping.

  In addition, as shown in FIG. 5, a pedestrian passage 3 for a pedestrian crossing the multi-layered cross structure is provided between the cross structure 1 and the rotary structure 2. In other words, in the present embodiment, the multilayer intersection structure has a three-layer structure in which the intersection structure 1, the pedestrian passage 3, and the rotary structure 2 are superimposed. Further, as shown in FIG. 5, the pedestrian passage 3 is installed at a different height from the crossing structure 1 and the rotary structure 2 through which the vehicle passes, and the crossing structure 1 and the rotary structure 2 through which the vehicle passes It is separated. Therefore, accidents between the vehicle and the pedestrian, such as a pedestrian accident involving the vehicle, can be effectively prevented.

  Further, the pedestrian passage 3 is provided with an entrance 31 for entering the pedestrian passage 3 from the ground and for advancing from the pedestrian passage 3 to the ground. In addition, an escalator 32 (which may be an elevator or a staircase) for accessing the entrance 31 is installed near the entrance 31. 1-4, illustration of the entrance 31 of the pedestrian passage 3 shown in FIG. 5 is omitted.

  In the present embodiment, a multi-layered cross structure is configured as described above.

In the present embodiment, the first ordinary road 10 of the first road 100 is a road that is not limited to vehicles that can pass, while the first specific road 20 of the first road 100 is a specific vehicle ( Hereinafter, it is a road through which only a specific vehicle can pass, that is, a vehicle other than the specific vehicle (hereinafter referred to as a normal vehicle) cannot pass through. As specific vehicles which can pass the 1st specific road 20, vehicles, such as a small vehicle, an emergency car, and an electric car, are mentioned, for example. In the present embodiment, the first specific road 20 is given a predetermined road marking such as paint or a road fence to clearly indicate that only the specific vehicle can pass through the first specific road 20. 1 The specific road 20 can pass only a specific vehicle. Thus, the particular vehicle, it is possible to both traveling first ordinary road 10 and the first specific road 20, between the lane 20 ₁ of the lane 10 ₁ and the first specific road 20 of the first ordinary road 10 , and you can change lanes between the lane 20 ₂ of lane 10 ₂ and the first specific road 20 of the first ordinary road 10. In contrast, ordinary vehicles other than the specific vehicle, it is not possible to traffic lane ₂₀ 1, 20 ₂ of the first specific road 20, a lane ₁₀ 1, 10 ₂ of the first ordinary road 10, the first specific A lane change between the lanes 20 ₁ and 20 ₂ of the road 20 is not possible. The second ordinary road 30 and the third ordinary road 50 are roads through which all vehicles (specific vehicles and ordinary vehicles) can pass, as with the first ordinary road 10, and the second specific road 40 and the second ordinary road 50 Similarly to the first specific road 20, the third specific road 60 is a road through which only specific vehicles can pass.

  As described above, the ordinary vehicle can pass only the first ordinary road 10, the second ordinary road 30, the third ordinary road 50, and the intersection structures 1a and 1b, and the first specified road 20 and the second specified road. The road 40, the third specific road 60, and the rotary structures 2a and 2b cannot pass. On the other hand, the specific vehicle is different from the normal vehicle, in addition to the first normal road 10, the second normal road 30, the third normal road 50, and the crossing structures 1a and 1b, the first specific road 20 and the second specific road 40. The third specific road 60 and the rotary structures 2a and 2b can also pass.

Therefore, when traveling from the first street 100 toward the second road 200, in the ordinary vehicle, for example, by entering the crossing structure 1a from the lane 10 ₁ of the first ordinary road 10, turn right crossing structure 1a, can progress to a lane 30 ₁ of the second ordinary road 30, also by a left turn of the crossing structure 1a, it can proceed to the lane 30 ₂ of the second ordinary road 30. As described above, the ordinary vehicle passes through the intersecting structures 1a and 1b in which the traffic signals 90a to 90d are installed. Therefore, when the ordinary vehicle passes through the intersecting structures 1a and 1b, the instructions of the signals 90a to 90d are given. Need to follow.

On the other hand, when proceeding from the first road 100 toward the second road 200, in certain vehicles, for example, as shown in FIG. 4 (A), passes through the rotary inlets 70a from the lane 20 ₁ of the first specific road 20 and, after entering the rotary structure 2a installed underground, the inside annular rotary structure 2a by circulating 90 °, it is possible to advance from the rotary inlet and outlet ports 80b in lane 40 ₁ of the second specific road 40 , also within the annular rotary structure 2a by orbiting 270 °, it is possible to advance from the rotary inlet and outlet ports 80d lane 40 ₂ of the second specific road 40. Thus, since the specific vehicle can pass through the rotary structures 2a and 2b where the traffic lights 90a to 90d are not installed, the specific vehicle can travel without waiting for a signal. In addition, for example, when the specific vehicle can travel in the traveling direction by the traffic lights 90a to 90d, the first ordinary road 10, the second ordinary road 30, the third ordinary road, like the ordinary vehicle. 50 and crossing structures 1a, 1b can also be passed.

Incidentally, the specific vehicle traveling toward the traffic lane 20 ₁ of the first specific road 20 in the Y axis negative direction via the rotary structure 2a, lane 20 ₁ of the first specific road 20 toward the Y axis negative direction as In the case of going straight, the specific vehicle enters the rotary structure 2a installed underground from the rotary entrance 70a, then turns around the annular rotary structure 2a by 180 °, and enters the first specific road 20 from the rotary exit 80c. so that the advances in lane 20 _1. In this case, as shown in FIG. 4 (B), the specific vehicle descends the inclined surface 71a that is lowered from the rotary entrance 70a toward the rotary structure 2a, and enters the rotary structure 2a installed underground. A first specific road installed on the ground level from the rotary advance port 80c by turning 180 ° around the rotary structure 2a installed in the basement, going up the inclined surface 81c from the rotary structure 2a toward the rotary advance port 80c. the progress to the lane 20 ₁ of 20.

  As described above, in the present embodiment, the intersecting structures 1a and 1b installed at the ground level are different from the rotary structures 2a and 2b installed so as to be located below the intersecting structures 1a and 1b. In the multi-layered intersection structure overlapped at the height position, the rotary structures 2a and 2b are connected to the rotary structures 2a and 2b adjacent to the rotary structures 2a and 2b by the first specific road 20, the second specific road 40, or the third specific road 60. It is connected to the rotary structures 2b and 2a. Thus, in this embodiment, the vehicle which passes the 1st normal road 10, the 2nd normal road 30, the 3rd normal road 60 and the rotary structure 2a, 2b where the vehicle which passes the cross structure 1a, 1b drive | works. Since the first specific road 20, the second specific road 40, and the third specific road 60 on which the vehicle travels are provided separately, the rotary structures 2a and 2b can be entered and advanced without providing a widening portion. A multi-layered cross structure can be constructed. As a result, the scale of the multilayer intersection structure can be reduced, and the construction cost for constructing the multilayer intersection structure can be reduced.

  In the multilayer intersection structure according to the present embodiment, only a specific vehicle can pass through the first specific road 20, the second specific road 40, the third specific road 60, and the rotary structures 2a and 2b. Therefore, in this embodiment, all the vehicles that travel in the multi-layered intersection structure are vehicles (mainly ordinary vehicles) that travel in the intersection structures 1a and 1b and vehicles that travel in the rotary structures 2a and 2b (only specific vehicles). And can be dispersed. As a result, it is possible to effectively prevent the traffic volume of the vehicle in the multi-layer crossing structure from being biased to one of the crossing structures 1a and 1b or the rotary structures 2a and 2b. Utilization efficiency can be increased and the traffic volume of the entire multi-layered intersection structure can be increased. Therefore, according to the present embodiment, the scale of the multilayer intersection structure can be made relatively small even in a place with a certain traffic volume such as an urban area, and the construction cost for constructing the multilayer intersection structure is further reduced. can do.

  Furthermore, in this embodiment, the vehicle which can pass the 1st specific road 20, the 2nd specific road 40, the 3rd specific road 60, and rotary structure 2a, 2b is limited only to a specific vehicle. Therefore, the traffic volume of the vehicle in the 1st specific road 20, the 2nd specific road 40, the 3rd specific road 60, and rotary structure 2a, 2b can be decreased, and, thereby, until a specific vehicle arrives at the destination Can be shortened. In addition, since no traffic lights are installed on the first specific road 20, the second specific road 40, the third specific road 60, and the rotary structures 2a and 2b, the specific vehicle is the first specific road 20, the second specific road The specific road 40, the third specific road 60, and the rotary structures 2a and 2b can travel without waiting for a signal, and the time until arrival at the destination can be further shortened. In addition, slow vehicles such as large vehicles are excluded from the specific vehicles, so the first specific road 20, the second specific road 40, the third specific road 60, and the rotary structures 2a and 2b are replaced with large vehicles. It is possible to prevent the slow-acceleration vehicle and the specific vehicle from being mixed with each other, whereby the time until the specific vehicle arrives at the destination can be further shortened.

  In addition, the rotary structures 2a and 2b according to the present embodiment are installed so as to be located underground of the intersecting structures 1a and 1b. Therefore, in the operation of the specific vehicle in the rotary structures 2a and 2b, it is possible to reduce the influence of the weather such as rain and snow, and the influence of direct sunlight or the western sun, so that it is possible to travel more safely.

  Moreover, in the multilayer intersection structure according to the present embodiment, the rotary structures 2a and 2b are installed so as to be located in the underground of the intersection structures 1a and 1b, and therefore the rotary structure is installed in the underground of the existing intersection structure. The multilayer intersection structure according to the present embodiment can be configured only by this. In particular, in the present embodiment, when a multi-layered crossing structure is configured using an existing crossing structure, the rotary structure can be installed in the basement of the existing crossing structure while using the existing crossing structure as it is. Therefore, it is possible to reduce the influence of the rotary structure installation work. As described above, the multilayer intersection structure according to this embodiment is easy to apply to the existing intersection structure.

  Furthermore, in this embodiment, as shown in FIG. 5, a pedestrian passage 3 for a pedestrian that crosses the multilayered cross structure is provided between the cross structure 1 and the rotary structure 2. Since this pedestrian passage 3 is installed separately from the crossing structure 1 and the rotary structure 2 through which the vehicle passes, the pedestrian and the vehicle are separated in the multi-layered crossing structure. The accident between the vehicle and the pedestrian can be effectively prevented, and the safety in the intersection structure 1 can be greatly improved. Further, by installing the pedestrian passage 3 for pedestrians crossing the multi-layered crossing structure and the crossing structure 1 through which the vehicle passes, in the crossing structure 1 in which the vehicle travels, Signal waiting for traffic can be eliminated, and the traffic volume of vehicles in the intersection structure 1 can be increased.

  The embodiment described above is described for facilitating understanding of the present invention, and is not described for limiting the present invention. Therefore, each element disclosed in the above embodiment is intended to include all design changes and equivalents belonging to the technical scope of the present invention.

  For example, in the embodiment described above, the intersecting structures 1a and 1b are installed at the ground level, and the rotary structures 2a and 2b are installed so as to be located in the basement of the intersecting structures 1a and 1b. For example, the rotary structures 2a and 2b may be installed at the ground level, and the intersecting structures 1a and 1b may be installed so as to be located underground of the rotary structures 2a and 2b.

  In the above-described embodiment, the two roads of the first ordinary road 10 and the second ordinary road 30 intersect with each other in the intersection structure 1a, and the two roads of the first ordinary road 10 and the third ordinary road 50 are present. However, the present invention is not limited to this configuration. For example, the crossing structures 1a and 1b may have a configuration in which three or more roads cross each other. Furthermore, in the above-described embodiment, it is possible to enter and advance into the rotary structure 2a from the two roads of the first specific road 20 and the second specific road 40, and the first specific road 20 and the third specific road. Although it is possible to enter and advance into the rotary structure 2b from 60 two roads, it is not limited to this configuration.
