[0033] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0034] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meanings as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0035] In the present invention, unless otherwise specified, the directional words used, such as "up" and "down", usually refer to the directions shown in the drawings, or to the vertical, perpendicular or gravity directions; similarly, for ease of understanding and description, "left" and "right" usually refer to the left and right shown in the drawings; "inside" and "outside" refer to the inside and outside relative to the outline of each component itself, but the above directional words are not used to limit the present invention.

[0036] In order to solve the problem in the prior art that vehicles on the up lane and the left turn lane of the traffic system are prone to collision and traffic accidents, the present application provides a plane traffic system and an urban traffic system having the same.

[0037] like Figure 1 and Figure 3As shown, the plane traffic system includes four groups of roads and four safety islands 10, and the four groups of roads are arranged around an intersection 20, wherein each group of roads includes a third right-turn down lane 81, a first right-turn up lane 82 and a second right-turn up lane 83. The third right-turn down lane 81 is located in the straight down lane 33. The first right-turn up lane 82 is connected to the third right-turn down lane 81, and the first right-turn up lane 82 is located in the up lane 32. The second right-turn up lane 83 is connected to the first right-turn up lane 82 and the adjacent road in the counterclockwise direction of the road, and the second right-turn up lane 83 is arranged on the side of the safety island 10 away from the intersection 20. The reverse left-turning vehicle passes through the up lane 32 of another road arranged opposite to the road, the third right-turn down lane 81, the first right-turn up lane 82 and the second right-turn up lane 83 in sequence, and then drives to the adjacent road in the clockwise direction of the road.

[0038] By applying the technical solution of this embodiment, during the reverse left-turn vehicle passage process, the vehicle sequentially passes through the up lane 32 of another road arranged opposite to the road, the third right-turn down lane 81 of the road, the first right-turn up lane 82 and the second right-turn up lane 83, and then drives to the road adjacent to the road in the clockwise direction to realize the reverse left turn of the vehicle. In the above process, the vehicle first drives into the road opposite to it, and then turns right to the road adjacent to it in the clockwise direction to realize the left turn of the vehicle, thereby avoiding the phenomenon of collision and friction between the straight-moving vehicle and the left-turning vehicle, thereby solving the problem of the vehicles on the up lane and the left-turning lane of the traffic system in the prior art being prone to collision and traffic accidents, and improving the safety factor of the traffic system.

[0039] In this embodiment, road surface monitors are provided on the first left-turn up lane 31 , the up lane 32 , the straight down lane 33 , the second left-turn up lane 34 , the right-turn down lane 35 , the third left-turn up lane 36 , the right-turn up lane 37 and the reverse left-turn lane 38 .

[0040] In this embodiment, the surface transportation system is an eleven-lane system.

[0041] It should be noted that the number of roads using the above-mentioned traffic mode is not limited thereto. Optionally, one, two or three groups of roads in the plane traffic system use the above-mentioned traffic mode.

[0042] In this embodiment, large vehicles such as buses can make a reverse left turn in the flat traffic system to realize a left turn at the intersection 20. At the same time, for small and medium-sized vehicles such as family cars that are not allowed to turn left directly at the intersection 20, the flat traffic system in this embodiment can be used to turn around on the next road and then return to the intersection 20 along the right turn lane to make a right turn, thereby finally realizing the left turn of the vehicle.

[0043] In this embodiment, the driving direction of a vehicle that turns left directly is changed to driving straight first, then turning around, and then turning right, which effectively avoids the intersection of left-turning vehicles and straight-moving vehicles, can reduce traffic accidents, and improve traffic speed. At the same time, the routes of the plane traffic system in this embodiment are just staggered, and there is no situation where the driving routes cross, which can reduce the frequency of traffic accidents.

[0044] In this embodiment, road surface monitors are provided on the first left-turn up lane 31 , the up lane 32 , the straight down lane 33 , the second left-turn up lane 34 , the right-turn down lane 35 , the third left-turn up lane 36 , the right-turn up lane 37 and the reverse left-turn lane 38 .

[0045] like Figure 2 As shown, the left-turn up lane of the road includes a first left-turn up lane 31, a second left-turn up lane 34 and a third left-turn up lane 36. The first left-turn up lane 31 is at a preset distance from the intersection 20, and the first left-turn up lane 31 is located in the up lane. The second left-turn up lane 34 is connected to the first left-turn up lane 31, and the second left-turn up lane 34 is arranged between the right-turn down lane and the straight down lane 33. The third left-turn up lane 36 is connected to the second left-turn up lane 34 and the adjacent road in the clockwise direction of the road, and the third left-turn up lane 36 is arranged on the side of the safety island 10 away from the intersection 20. The left-turn up lane passes through the first left-turn up lane 31, the second left-turn up lane 34 and the third left-turn up lane 36 in sequence and then drives to the adjacent road in the clockwise direction of the road.

[0046] Specifically, during the passage of left-turning upward vehicles, the vehicles pass through the first left-turn upward lane 31, the second left-turn upward lane 32 and the third left-turn upward lane 36 in sequence and then drive to the adjacent road in the clockwise direction of the road. The vehicles driving on the upward lane 32 and the vehicles driving on the third left-turn upward lane 36 (the second left-turn upward lane 32) have different routes and there is no route negotiation. Therefore, there will be no collision or friction between straight-moving vehicles and left-turning vehicles, thereby solving the problem in the prior art that vehicles on the upward lane and the left-turn lane of the traffic system are prone to collision and traffic accidents, thereby improving the safety factor of the traffic system.

[0047] like Figure 2 and Figure 3 As shown, the first right-turn upper lane 82 is located on a side away from the center of the road of the first left-turn upper lane 31. Specifically, the first right-turn upper lane 82 and the first left-turn upper lane 31 are both located within the upper lane 32, and the vehicle can turn right on the first right-turn upper lane 82 and turn left on the first left-turn upper lane 31 to meet different driving route requirements of the vehicle.

[0048] like Figure 2 and Figure 3 As shown, each group of roads also includes an adjustment area 40. The adjustment area 40 includes a sub-adjustment area, through which the first left-turn up lane 31 and the second left-turn up lane 34 are connected, and the sub-adjustment area is used to guide the left-turn up lane vehicles traveling on the first left-turn up lane 31 to the second left-turn up lane 34. At the same time, the third right-turn down lane 81 and the first right-turn up lane 82 are connected through the sub-adjustment area, and the sub-adjustment area is used to guide the reverse left-turn vehicles traveling on the third right-turn down lane 81 to the first right-turn up lane 82. In this way, the vehicle can stop in the sub-adjustment area, and then switch to the second left-turn up lane 34 when the straight down lane 33 is blocked, so as to ensure that the left-turning vehicle will not affect the normal driving of the vehicle on the straight down lane 33. At the same time, when the first left-turn up lane 31 is impassable, vehicles can turn from the third right-turn down lane 81 to the first right-turn up lane 82, ensuring that vehicles turning left in the opposite direction will not affect the normal driving of vehicles in the straight down lane 33 and the first left-turn up lane 31.

[0049] Specifically, when a vehicle traveling in the upper lane 32 needs to turn left, it first switches to the first left-turn upper lane 31. When the straight down lane 33 is in a passable state, the vehicle needs to stop in the sub-adjustment area and then enter the second left-turn upper lane 34 when the straight down lane 33 is no longer passable.

[0050] Specifically, when a vehicle traveling in the third right-turn down lane 81 needs to turn around, it first observes whether the first left-turn up lane 31 is passable. When the first left-turn up lane 31 is passable, the vehicle needs to stop and wait in the sub-adjustment area, and then enter the first right-turn up lane 82 when the first left-turn up lane 31 is not passable.

[0051] like Figure 2 As shown, the sub-adjustment area includes a first adjustment lane 41, and the first adjustment lane 41 is arranged at an obtuse angle with the first left-turn up lane 31 and the second left-turn up lane 34. The first left-turn up lane 31 is arranged in parallel with the second left-turn up lane 34, and the second left-turn up lane 34 is arranged closer to the center of the road relative to the first left-turn up lane 31, thereby ensuring that the vehicles on the second left-turn up lane 34 will not affect the normal driving of the vehicles on the up lane 32.

[0052] like Figure 2As shown, the adjustment area 40 also includes a second adjustment lane 42, and the straight down lanes 33 of each group of roads include a first straight down lane 331 and a second straight down lane 332. The second straight down lane 332 is arranged in parallel with the first straight down lane 331, and the first straight down lane 331 is connected to the second straight down lane 332 through the second adjustment lane 42, and the second adjustment lane 42 is arranged at an obtuse angle to the first straight down lane 331 and the second straight down lane 332. In this way, the above arrangement ensures that vehicles traveling on the first straight down lane 331 can smoothly switch to the second straight down lane 332 through the second adjustment lane 42, thereby improving the driving smoothness of the plane traffic system.

[0053] like Figure 3 As shown, the adjustment area also includes a third adjustment lane 43, through which the first right-turn up lane 82 and the second right-turn up lane 83 are connected, and the third adjustment lane 43 is arranged at an obtuse angle with the first right-turn up lane 82 and the second right-turn up lane 83. Among them, the first right-turn up lane 82 is arranged in parallel with the second right-turn up lane 83, and the first right-turn up lane 82 is arranged closer to the center of the road relative to the second right-turn up lane 83, thereby ensuring that the vehicles on the second right-turn up lane 83 will not affect the normal driving of the vehicles on the up lane 32.

[0054] like Figure 4 As shown, the right-turn down lane 35 of each group of roads includes a first right-turn down lane 351, a second right-turn down lane 352 and a transition lane 353. Among them, the second right-turn down lane 352 is arranged in parallel with the first right-turn down lane 351, and the second right-turn down lane 352 is arranged on the side of the third left-turn up lane 36 away from the intersection 20. The first right-turn down lane 351 and the second right-turn down lane 352 are connected by the transition lane 353, and the transition lane 353 and the first right-turn down lane 351 and the second right-turn down lane 352 are arranged at an obtuse angle. Among them, the first right-turn down lane 351 is arranged near the center of the road relative to the second right-turn down lane 352. In this way, the above arrangement can avoid vehicles turning left on the up lane 32, prevent left-turn vehicles from colliding or rubbing with right-turn vehicles, and thus improve the safety of the plane traffic system.

[0055] like Figures 1 to 4 As shown, each group of roads also includes an auxiliary channel 50. The road curb and the safety island 10 are connected through the auxiliary channel 50, and the auxiliary channel 50 passes through the second right-turn down lane 352 and the third left-turn up lane 36. Pedestrians and non-motor vehicles can move between the curb and the safety island 10 through the auxiliary channel 50 to achieve the circulation of pedestrians and non-motor vehicles on each group of roads.

[0056] like Figure 1 As shown, each group of roads also includes a separation strip 60. The separation strip 60 is set between the up lane 32 and the straight down lane 33 to separate the up vehicles and down vehicles on the road, wherein the sub-adjustment area is arranged to avoid the separation strip 60. In this way, the up lane 32 is separated from the straight down lane 33 by the separation strip 60, so as to prevent the vehicles on the up lane 32 and the straight down lane 33 from driving in disorder, thereby improving the safety and smoothness of the plane traffic system and preventing traffic jams. In this way, the sub-adjustment area interrupts the separation strip 60 to prevent vehicles in the adjustment area 40 from parking or driving on the separation strip 60 and affecting the normal operation of the plane traffic system.

[0057] In other embodiments not shown in the attached drawings, each group of roads further includes a double yellow line. The double yellow line is arranged between the up lane and the straight down lane to separate the up vehicles and down vehicles on the road, wherein the adjustment area is arranged to avoid the double yellow line. In this way, the above arrangement prevents vehicles in the adjustment area from parking or driving on the double yellow line and affecting the normal operation of the plane traffic system.

[0058] In this embodiment, each group of roads further includes a reverse left turn lane 38, and the right side of the isolation belt 60 is sequentially provided with a reverse left turn lane 38, three straight up lanes 321, and a right turn up lane 37, and the right side of the right turn up lane 37 is an auxiliary channel 50. The left side of the isolation belt 60 is sequentially provided with a third right turn down lane 81, three straight down lanes 33, a second left turn up lane 34, and a right turn down lane 35, and the left side of the right turn down lane 35 is an auxiliary channel 50. Among them, the first left turn up lane 31 is a straight up lane closest to the isolation belt 60 among the three straight up lanes 321, the second left turn up lane 34 is located between the right turn down lane 35 and the straight down lane 33, and the right turn down lane 35 is connected to the second right turn up lane 83. When a vehicle traveling on the first left-turn up lane 31 needs to turn left, the vehicle changes lanes and enters the sub-adjustment area. When the straight down lane 33 is in an impassable state, the vehicle continues to drive into the second left-turn up lane 34, and enters the third left-turn up lane 36 via the second left-turn up lane 34 to realize the left turn of the vehicle. When a vehicle traveling on the third right-turn down lane 81 needs to turn left, when the first left-turn up lane 31 is in an impassable state, the vehicle continues to drive into the first right-turn up lane 82, and enters the second right-turn up lane 83 via the first right-turn up lane 82 to realize the reverse left turn of the vehicle.

[0059] like Figure 1 and Figure 2 As shown, along the direction from the isolation strip 60 to the curb of the road, the stop line of the upper lane 32 is gradually arranged close to the safety island 10.

[0060] like Figure 1 As shown, each group of roads also includes a first traffic light 71, a second traffic light 72, a third traffic light 73, a fourth traffic light 74 and a fifth traffic light 75. Among them, the first traffic light 71 is used to indicate the driving status of vehicles traveling in the sub-adjustment area, and the second traffic light 72 is used to indicate the driving status of vehicles traveling at the intersection 20. The third traffic light 73 is used to indicate the driving status of vehicles traveling in the third left-turn up lane 36. The fourth traffic light 74 is used to indicate the driving status of vehicles traveling in the right-turn up lane 37. The fifth traffic light 75 is used to indicate the passage of pedestrians and non-motor vehicles. In this way, each traffic light is used to indicate the driving status of the corresponding lane, thereby ensuring the orderly operation of the plane traffic system.

[0061] Specifically, when the red light of the first traffic light 71 is on, vehicles in the sub-adjustment area cannot drive, and can only drive when the green light is on. When the red light of the second traffic light 72 is on, vehicles in the up lane 32 and the straight down lane 33 cannot drive, and can only drive when the green light is on. When the red light of the third traffic light 73 is on, vehicles on the third left-turn up lane 36 cannot drive, and can only drive when the green light is on. When the red light of the fourth traffic light 74 is on, vehicles on the right-turn up lane 37 cannot drive, and can only drive when the green light is on. When the red light of the fifth traffic light 75 is on, the auxiliary channel is not passable, and can only drive when the green light is on. In this way, through the above settings, it is possible to prompt and remind driving vehicles, pedestrians and non-motorized vehicles, realize red light stop and green light go, and ensure the orderliness and fluency of the plane traffic system. Among them, the color displayed by each traffic light is switched according to the corresponding lane to ensure the fluency of each lane.

[0062] In this embodiment, the first traffic light 71 includes a first straight signal light, a first left turn signal light and a first reverse left turn signal light, the second traffic light 72 includes a second straight signal light, the third traffic light 73 includes a second left turn signal light, and the fourth traffic light 74 includes a right turn signal light. The fifth traffic light 75 includes a first pedestrian and non-motor vehicle signal light and a second pedestrian and non-motor vehicle signal light, wherein the first pedestrian and non-motor vehicle signal light is arranged in a direction parallel to the straight lane, and the second pedestrian and non-motor vehicle signal light is arranged in a direction perpendicular to the third left turn up lane 36.

[0063] In this embodiment, the first straight signal light and the first left turn signal light are turned on synchronously to indicate green light, and the first left turn signal light is turned on red light to indicate a first preset time ahead of the first straight signal light. In this way, the first straight signal light and the first left turn signal light are turned on synchronously to enable the vehicle to change lanes from the first left turn up lane 31 to the sub-adjustment area. When the red light of the first straight signal light is on, the road perpendicular to the road is in a traffic state, and the vehicle cannot turn left. Therefore, it is necessary to turn the red light of the first left turn signal light on before the red light of the first straight signal light is on, and the vehicle cannot turn left, thereby preventing the left-turning vehicle from affecting the driving of the straight-moving vehicle.

[0064] In this embodiment, the second straight-through signal light turns on the green light indication after a second preset time than the first straight-through signal light, and the second straight-through signal light turns on the red light indication after a third preset time than the first straight-through signal light. In this way, the above time setting can not only prevent the vehicles on the perpendicular roads from interfering with each other's routes, but also prevent the left-turning vehicles from interfering with the straight-through vehicles, thereby improving the smoothness and safety of the plane traffic system.

[0065] In this embodiment, the second left turn signal light turns on the green light indication after the fourth preset time than the first left turn signal light, and the second left turn signal light turns on the red light indication after the fifth preset time than the first left turn signal light. In this way, the above time setting ensures that the vehicle entering the third left turn up lane 36 can realize the left turn.

[0066] In this embodiment, when the first reverse left turn signal light turns on green, the first straight line signal light turns on red; when the first reverse left turn signal light turns on red, the first straight line signal light turns on green.

[0067] In this embodiment, each group of roads further includes a deceleration sign, wherein the deceleration sign is disposed on one side of the adjustment area 40, and the deceleration sign is used to instruct vehicles traveling in the adjustment area 40 to travel at the recommended speed.

[0068] In this embodiment, each group of roads further includes a first fence and a second fence. The first fence is arranged on both sides of the second left-turn up lane 34, and is used to isolate vehicles traveling on the second left-turn up lane 34 from the curb of the road. The second fence is arranged on both sides of the third left-turn up lane 36, and is used to isolate vehicles traveling on the third left-turn up lane 36 from the curb of the road. In this way, the first fence can prevent vehicles between the second left-turn up lane 34 and the straight down lane 33 from driving into the wrong lane. The second fence can prevent vehicles between the third left-turn up lane 36 and the right-turn up lane 37 from driving into the wrong lane, thereby improving the orderliness of the plane traffic system.
