Description

Technical Field

[0005]

[0001] The present invention relates to a novel reverse vehicle guiding road structure and a fence used therefor. Specifically, the present invention relates to a reverse vehicle guiding road structure and a fence used therefor, which enable a reverse vehicle to smoothly and safely return to the normal lane, reduce traffic jams, driving delays of vehicles traveling on the normal lane and the reverse lane, and the occurrence of traffic accidents caused thereby, and maintain a high traffic flow rate.

Background Art

[0002] So-called reverse driving accidents, which occur due to vehicles driving in the opposite direction to the vehicle driving direction indicated by road signs or road surface markings (reverse driving), occur not only on ordinary roads but also on highways. In particular, on highways, 2,430 accidents occurred during the 12-year period from 2011 to 2022, and the number is increasing year by year.

[0003] In addition, in terms of the number of reverse driving cases, the proportion of property damage or personal accidents (reverse driving accidents) accounts for about 20% (492 out of 2,430 reverse driving cases from 2011 to 2022). Here, 10% of the property damage and personal accidents are fatal accidents. In addition, the proportion of fatal accidents in reverse driving accidents on highways is about 39 times that in reverse driving accidents on ordinary roads, so it can be said that the danger is extremely high.

[0004] In view of the seriousness of such reverse driving accidents, various reverse driving prevention methods have been proposed. For example, at a branch point where the main line merges or diverges, a method of installing a no-entry sign or a one-way sign, or providing a no-entry marking or a one-way marking on the road surface to call the driver's attention can be mentioned.

[0005] However, these reverse driving accident prevention methods are only for preventing a driver from entering the reverse lane. That is, assuming a case where a vehicle has entered the reverse lane, it does not consider until the reverse vehicle safely and smoothly returns to the normal lane (regular lane).

[0006] On the other hand, as a method for returning a vehicle traveling in the wrong direction to the correct direction, for example, Patent Document 1 discloses a road structure for guiding vehicles traveling in the wrong direction to safely guide them and prevent accidents.

[0007] Specifically, the road structure for guiding vehicles traveling in the wrong direction is described as "a road structure for guiding vehicles traveling in the wrong direction to safely prevent accidents, wherein a guidance lane is formed to the right of the driving lane relative to the direction of travel of vehicles traveling in the correct direction, the guidance lane branches off from the driving lane in the opposite direction of travel, has a predetermined distance along the driving lane that vehicles can enter and travel on, and has a dead end at its end, with lane markings placed on the boundary line between the driving lane and the guidance lane, and boundary poles or guardrails installed in a predetermined distance from the end of the guidance lane."

[0008] [Prior art documents] [Patent Documents]

[0009] [Patent Document 1] Patent No. 6844884 [Overview of the project] [Problems that the invention aims to solve]

[0010] However, the road structure for guiding vehicles traveling in the wrong direction disclosed in Patent Document 1 is a guide road that extends from the road closest to the median strip (the road traveling in the wrong direction) among multiple roads. A system is in place. Although vehicles traveling in the wrong direction can be avoided by entering the taxiway from the wrong-way lane, when entering the right-way lane from the taxiway, it is necessary to give due consideration to oncoming oncoming vehicles. As a result, it is not easy to enter the right-way lane smoothly, and furthermore, vehicles remaining on the taxiway make it difficult for vehicles traveling in the wrong direction to enter the taxiway from the wrong-way lane, which raises concerns about congestion and delays for vehicles traveling on both the right-way and wrong-way lanes.

[0011] In order to solve the above-mentioned problems of the prior art, the inventors have conducted diligent studies and have found a fence that guides vehicles traveling in the wrong direction on a road in the wrong direction, guiding the vehicle traveling in the wrong direction to a central bypass road provided in the median strip, and enabling the vehicle to smoothly transition to the road in the right direction (without remaining on the central bypass road for a long period of time) while avoiding collisions with vehicles traveling in the right direction behind it when it enters the road in the right direction from the central bypass road.

[0012] In other words, the present invention aims to provide a road structure that guides vehicles traveling in the wrong direction, which allows a vehicle that should be entering the correct direction road to enter the wrong direction road in a smooth and safe manner, and reduces congestion, delays, and resulting traffic accidents for vehicles traveling on both the correct and wrong directions, thereby maintaining a high traffic flow rate. [Means for solving the problem]

[0013] The road structure for guiding vehicles traveling in the wrong direction according to the present invention comprises at least a first multi-lane road (10) for vehicles to travel on, having a first lane (10a), an overtaking lane (10b), and a center line (10c) provided between them. A second multi-lane road (20) is a multi-lane road for vehicles to travel in the opposite direction to the direction of travel of vehicles on the first multi-lane road (10), and is a multi-lane road having at least a first lane (20a), an overtaking lane (20b), and a center line (20c) provided between them, A median strip (30) is installed between the first double-lane road (10) and the second double-lane road (20), The aforementioned median strip (30) is a road structure for guiding vehicles traveling in the wrong direction, including a central bypass road (40) that allows vehicles to travel from the second double-lane road (20) to the first double-lane road (10), A vehicle guidance fence (50) and / or a vehicle guidance fence (50) extending from the passing lane (20b) to the central bypass road (40) to guide vehicles traveling in the wrong direction in the passing lane (20b) to the central bypass road (40), It is characterized by having a forward-moving vehicle guiding fence (60) that extends from the overtaking lane (10b) to the first lane (10a) and guides vehicles moving forward in the overtaking lane (10b) to the first lane (10a).

[0014] Moreover, in the oncoming vehicle guiding road structure according to the present invention, it is preferable to have the oncoming vehicle guiding fence (50) and the forward-moving vehicle guiding fence (60).

Effects of the Invention

[0015] According to the oncoming vehicle guiding road structure of the present invention, even when a vehicle that should enter the forward lane enters the oncoming lane, the vehicle (oncoming vehicle) can smoothly and safely return to the forward lane, and it can reduce traffic congestion, travel delays of vehicles traveling on the forward lane and the oncoming lane, and the occurrence of traffic accidents caused thereby, and maintain a high traffic flow rate.

DETAILED DESCRIPTION OF THE INVENTION

[0022] Hereinafter, the reverse-travel vehicle guiding road structure according to the present invention and the fences used therefor will be described in detail with reference to the drawings as appropriate.

[0023] The reverse-travel vehicle guiding road structure according to the present invention is used on a road on which vehicles such as passenger cars, buses, trucks, and motorcycles travel. Here, the road includes not only general roads but also expressways. More specifically, as shown in FIGS. 1 to 4, it is a road that is defined to travel in opposite directions and has two multi-lane roads on one side with a median strip 30 interposed therebetween. Here, the first multi-lane road 10 is composed of a first lane 10a, an overtaking lane 10b, and a center line 10c provided therebetween.

[0024] On the other hand, the second multi-lane road 20 is a multi-lane road for vehicles to travel in the opposite direction to the travel direction of the vehicles on the first multi-lane road 10. The second multi-lane road 20 is a roadway having a first lane 20a, an overtaking lane 20b, and a center line 20c provided therebetween. In FIGS. 1 to 4, these multi-lane roads are exemplified as being composed of a two-lane road (the first lane and the overtaking lane), but for example, it may be a three-lane road or more, such as having a second lane between the first lane and the overtaking lane. Furthermore, from the perspective of avoiding congestion near the central bypass, it is preferable to have multiple lanes between the overtaking lane 20b and the first lane 20a near the central bypass.

[0025] In addition, the "passing lane" is the lane closest to the median strip on a multi-lane road with two or more lanes, while the "first lane" is the lane furthest from the median strip.

[0026] Note that the numbering Y1-3 and Z2-3 in Figure 2 indicate vehicles traveling in the correct direction on the first double-lane road (forward-moving vehicles) and vehicles traveling in the correct direction on the second double-lane road (forward-moving vehicles), respectively. Here, "forward-moving vehicles" are vehicles that travel in the direction specified by road markings such as those shown in the numbering X1 and X2, or by road signs erected near the road (not shown in the illustration), on the lane they are traveling in.

[0027] On the other hand, a "vehicle traveling in the wrong direction," as indicated by the number Z1 in Figure 2, refers to a vehicle traveling in the opposite direction to the direction specified by road markings, etc.

[0028] As shown in Figures 1-4, in the road structure for guiding vehicles traveling in the wrong direction according to the present invention, the median strip 30 is provided with a central bypass road that enables vehicles (vehicles traveling in the wrong direction) to travel from the second multi-lane road 20 to the first multi-lane road 10. Here, "enabling vehicles (vehicles traveling in the wrong direction) to travel from the second multi-lane road 20 to the first multi-lane road 10" means that a vehicle traveling in the wrong direction Z1 can enter the central bypass road 40 from the overtaking lane 20b of the second multi-lane road 20 in which it is traveling in the wrong direction, and can then enter the overtaking lane 10a of the first multi-lane road 10 from the central bypass road 40 and return to the first multi-lane road 10, which is the road in the correct direction. In other words, a vehicle can travel from the second multi-lane road 20 to the first multi-lane road 10 via the central bypass road 40, and even if there are some bumps or uneven surfaces, the road is in a condition where normal vehicles can travel.

[0029] Furthermore, the road structure for guiding vehicles traveling in the wrong direction according to the present invention includes a vehicle guidance fence for vehicles traveling in the wrong direction, as shown by the number 50 in Figures 1 to 4, which extends from the overtaking lane 20b to the central bypass road 40. Here, the vehicle guidance fence 50 for vehicles traveling in the wrong direction in the overtaking lane 20b (vehicle traveling in the wrong direction Z1) is used to guide the vehicle traveling in the wrong direction to the central bypass road 40.

[0030] Furthermore, the road structure for guiding vehicles traveling in the wrong direction according to the present invention includes a fence for guiding vehicles traveling in the correct direction, which extends from the overtaking lane 10b to the first lane 10a, as shown by the number 60 in Figures 1 to 4. Here, the fence for guiding vehicles traveling in the correct direction in the overtaking lane 10b (vehicles traveling in the correct direction) is used to guide them to the first lane 10a.

[0031] Furthermore, as shown in Figures 2-3, the vehicle traveling in the wrong direction, Z1, is encouraged to proceed along the wrong-way vehicle guidance fence 50 (preferably with road markings such as those shown in X3 along with the wrong-way vehicle guidance fence 50) onto the central bypass road 40. Moreover, as shown in Figure 4, the wrong-way vehicle Z1 can enter the overtaking lane 10b from the central bypass road 40, and as a result, can return to the first double-lane road which is the normal-direction road.

[0032] Furthermore, as shown in Figure 2, in the overtaking lane 20b, the vehicle traveling in the correct direction Z3 travels in the opposite direction to the vehicle traveling in the wrong direction Z1. The vehicle traveling in the correct direction Z3 is guided from the overtaking lane 20b to the first lane 20a by the wrong-way vehicle guidance fence 50. As a result, while avoiding accidents such as a head-on collision between the wrong-way vehicle Z1 and the vehicle traveling in the correct direction Z3, the wrong-way vehicle Z1 can enter the central detour road 40 and leave the overtaking lane 20b, which is the wrong-way road, as shown in Figure 3.

[0033] Next, as shown in Figures 3-4, the vehicle Z1 traveling in the wrong direction enters the overtaking lane 10b of the first double-lane road 10, which is the normal direction of travel, from the central bypass road 40, and returns to the normal direction of travel. In this case, the vehicle traveling in the wrong direction, Z1, and the vehicle traveling in the correct direction, Y1, which is traveling behind the vehicle traveling in the wrong direction as indicated by the number Y1, will be guided from the passing lane 10b to the first lane 10a due to the presence of the vehicle guidance fence 60, and will travel in the first lane 10a. In other words, there is no concern that the vehicle traveling in the wrong direction will collide with the vehicle traveling in the correct direction Y1 behind it. Furthermore, since there is no concern of collision between the vehicle traveling in the wrong direction Z1 and the vehicle traveling in the correct direction Y1 behind it, it can enter the first lane 10a smoothly with less stopping time on the central bypass road 40 or without significantly reducing its speed. As a result, on the first multi-lane road 10 (especially the overtaking lane 10b), which is the correct direction road, it is possible to reduce the speed reduction of vehicles traveling in the correct direction behind the vehicle traveling in the wrong direction Z1, and to reduce the occurrence of problems such as congestion.

[0034] In other words, the road structure for guiding vehicles traveling in the wrong direction according to the present invention preferably includes a fence 50 for guiding vehicles traveling in the wrong direction and a fence 60 for guiding vehicles traveling in the right direction, as shown in Figures 1 to 4. In such an embodiment, vehicles traveling in the wrong direction can return to the right direction road smoothly and safely, and congestion, delays, and resulting traffic accidents for vehicles traveling on both the right and wrong direction roads can be reduced, thereby maintaining a high traffic flow rate (traffic volume measured on an hourly basis).

[0035] Furthermore, as shown in Figure 5, the system may have a reverse-direction vehicle guidance fence 50 but no forward-direction vehicle guidance fence 60, or as shown in Figure 6, the system may have a forward-direction vehicle guidance fence 60 but no reverse-direction vehicle guidance fence 50.

[0036] Furthermore, the wrong-way vehicle guidance fence 50 and the right-way vehicle guidance fence 60 may be permanently installed, or they may be housed in the median strip or central bypass when no wrong-way vehicles are detected, but may be automatically or manually installed when a wrong-way vehicle is detected. In addition, the material of the wrong-way vehicle guidance fence 50 and the right-way vehicle guidance fence 60 is not particularly limited and may be plastic, stainless steel (registered trademark) or other metal, and buffer material may be installed on the fence surface as needed. Furthermore, the reverse-direction vehicle guidance fence 50 and the forward-direction vehicle guidance fence 60 may be general fences (physical fences) as described above, but if the reverse-direction vehicle or the forward-direction vehicle is equipped with autonomous driving technology such as white line detection technology using electromagnetic methods (for example, sensor technology), then a physical fence may not be necessary. In this case, the white lines would function as a virtual fence. For example, the reverse-direction vehicle guidance fence 50 and the forward-direction vehicle guidance fence 60 could be composed of white lines (virtual fences), and the reverse-direction vehicle and the forward-direction vehicle could be guided along these white lines. Furthermore, as mentioned above, even in embodiments equipped with autonomous driving technologies such as white line detection technology, physical fences may be provided as appropriate.

[0037] To alert drivers to the presence of wrong-way vehicle guidance fences and right-way vehicle guidance fences, guidance lamps or signs (flat signs, laser image signs, three-dimensional signs, etc.) may be provided on or near the wrong-way vehicle guidance fence 50 and the right-way vehicle guidance fence 60. [Industrial applicability]

[0038] According to the present invention, it is possible to provide a road structure that guides vehicles traveling in the wrong direction, enabling them to return to the correct direction road smoothly and safely, while reducing congestion, delays, and resulting traffic accidents for vehicles traveling on both the correct and wrong-direction roads, and maintaining a high traffic flow rate.
