Description

The present invention relates to a road structure capable of guiding a reverse-way vehicle on a highway, a one-way road, or the like. It is about the road structure to prevent it.

Conventionally, on expressways and one-way roads, the entrance and exit are misunderstood, or a U-turn is made because the vehicle has passed the desired exit. You can often see cars running. The existence of such a reverse-way vehicle has a risk of causing a collision accident with a vehicle traveling in the correct traveling lane, and many such accidents actually occur. As a countermeasure against such a reverse-way vehicle, a warning means to make the reverse-way vehicle recognize the reverse-way driving state at an early stage, and a driver who is regularly driving the existence of the reverse-way vehicle are surely recognized. It is necessary to take measures to prevent collision accidents by notifying them. In addition, there is a demand for a road structure that not only recognizes the vehicle but also physically stops the vehicle from traveling.

As a warning means to recognize the reverse-way driving condition, for example, a sensor detects a car running in reverse at the exit of a highway, a communication device is used to notify the police, a door-type bar is opened and closed, and a lamp on the car running in reverse is used. A "communication system that detects the reverse driving of an automobile at the exit of a highway and turns on a lamp" (Patent Document 1) has been proposed and is a known technique. Specifically, when a sensor that detects a car running in reverse at the exit of a highway, a communication device that reports to the police when the sensor detects a car running in reverse, and a sensor that detects a car running in reverse In addition, there is a door-type bar that opens and closes, and a lamp with a communication function that is installed on the vehicle of a reverse-way vehicle and lights up when the sensor detects that the vehicle is running in reverse. , Is a technical proposal formed with.

However, according to the proposal of "a communication system that detects the reverse driving of a car at the exit of a highway and turns on a lamp", the road on which the reverse driving vehicle and the regular driving vehicle travel is the same road. If the door-type bar is activated by a sensor that detects a reverse-way vehicle, the door-type bar will also stop the regular vehicle from running, which may cause confusion at the entrance and exit, and the warning lamp lights up to reverse the situation. A means to visually warn a driving driver is a technology that may not be noticed by a reverse-way driver, and can safely and surely guide a reverse-way vehicle to prevent a collision accident. It wasn't a suggestion.

In addition, a "reverse-way driving prevention system, a reverse-way driving system, and a reverse-way driving warning device" that can make a driver of a reverse-way driving vehicle who thinks that it is not a reverse-way driving aware of the fact that the driving is a reverse-way driving (Patent Document 2). Has been proposed and has become a known technique. Specifically, a reverse-way vehicle detection device installed in the exit passage of a high-standard highway and / or an urban expressway, and a predetermined length along the exit passage when the reverse-way vehicle detection device detects a reverse-way vehicle. It is a technical proposal made up of powerful lights that are arranged so that the driver of a reverse-way vehicle can continue to see.

However, according to the proposal of such "reverse driving prevention system, reverse driving prevention system and reverse driving warning device", the driver of the reverse driving vehicle who thinks that it is not reverse driving is driven in reverse by visual lighting means. Since we are trying to make people aware that they are driving, there is a possibility that the driver of the reverse-way vehicle may overlook it without recognizing that it is a reverse-way driving, and guide the reverse-way vehicle safely and surely to prevent a collision accident. It was not a technical proposal that could be prevented.

Further, a "reverse-way driving prevention device" (Patent Document 3) has been proposed, which enables each vehicle to safely drive by making the driver of the vehicle notice the reverse-way driving in advance, and is a known technique. Specifically, for vehicles exiting from the parking lot to a one-way street, a sign indicating the exit direction is installed along the exit direction, and the sign is given an arrow pointing in the exit direction. It is a technical proposal provided with a light emitting unit that emits light continuously or intermittently.

However, according to the proposal of such "reverse driving prevention device", it is trying to make the driver of the reverse driving vehicle who thinks that it is not reverse driving to recognize that he is driving in reverse by visual marking means. Therefore, there is a possibility that the driver of the reverse-way vehicle may overlook it without recognizing that it is a reverse-way drive, and it was not a technical proposal that can guide the reverse-way vehicle safely and surely and prevent a collision accident. ..

Furthermore, "Wrong-way driving prevention road structure and reverse-way driving prevention road device" that can give a warning to a vehicle running in reverse without installing a dedicated device to warn the vehicle of reverse-way driving (reverse driving prevention road structure and reverse-way driving prevention road device) Patent Document 4) has been proposed and is a known technique. Specifically, it is a slope-shaped reverse-running prevention road structure provided in the lane portion of a one-way road, and has a step portion vertically protruding from the road surface along the width direction of the one-way road and a step portion. In the technical proposal, the road is extended in the reverse direction of the one-way road, and the height dimension from the road surface gradually decreases toward the reverse direction to reach the road surface. be.

However, according to the proposal of "Wrong-way driving prevention road structure and reverse-way driving prevention road device", the impact of the step on the reverse driving caused by the driver's distraction (sleeping, carelessness, vagueness, crazy about conversation, etc.) It makes you recognize that you are running in reverse, and due to the stepped portion that protrudes vertically, it will give a considerable impact to a regular running vehicle as well as a reverse running vehicle. It is difficult to distinguish whether or not the impact is a reverse drive, and as a result, it may not be recognized as a reverse drive, so in a technical proposal that can guide a reverse drive safely and surely and prevent a collision accident. There wasn't.

The applicant pays attention to the road structure and devices for preventing reverse-way driving on expressways and one-way roads as described above, and guides the reverse-way driving vehicle to deviate from the regular driving lane. Based on the idea that it is possible to prevent a collision accident with a vehicle, we have developed a road structure that can safely and surely guide a reverse-way vehicle by using physical and sensory means. This leads to the proposal of "reverse vehicle guidance road structure".

In view of the above problems, the present invention guides a reverse-way vehicle safely and surely by using physical and sensory means on a highway, a one-way road, or the like to prevent a collision accident. The challenge is to provide a road structure.

In order to solve the above problems, the present invention is a reverse vehicle guidance road structure for safely guiding a reverse vehicle to prevent an accident, and is located on the right side of the traveling lane with respect to the traveling direction of the regular traveling vehicle. A guidance lane is formed in the vehicle, and the guidance lane branches from the traveling lane in the direction opposite to the traveling direction, has a predetermined mileage in which the vehicle can travel along the traveling lane, and ends at the end. Take the means formed in.

Further, the present invention adopts a means in which a lane road marking is attached on the boundary line between the traveling lane and the guidance lane, and a boundary pole or a guardrail is attached to a section at a predetermined distance from the end.

Furthermore, the present invention employs a means comprising a warning means for making the driver recognize that the driver is in a reverse driving state at an arbitrary position in the guidance lane.

Further, the present invention also employs a means in which a communication means capable of communicating with the outside such as an intercom is installed near the end of the guidance lane.

According to the reverse-traveling vehicle guidance road structure according to the present invention, the guidance lane having a predetermined mileage that the reverse-traveling vehicle can travel until the reverse-traveling vehicle notices the reverse-traveling is branched from the regular traveling lane and becomes the traveling lane. Since it is formed along the route, not only the entrance / exit lanes of interchanges, service areas, and parking areas, which are mentioned as places where reverse driving is likely to occur, but also lanes such as expressways and toll roads and medians are provided. It has an excellent effect that it can be adopted as a road structure on all roads such as general roads and one-way roads.

In Japan, where left-hand driving is adopted, a reverse-way vehicle tends to drive in the leftmost lane in the reverse-way direction. In that respect, according to the reverse traveling vehicle guidance road structure according to the present invention, the guiding lane is formed on the right side of the traveling lane with respect to the traveling direction of the regular traveling vehicle, so that the guiding lane is formed for the reverse traveling vehicle. It will be in the leftmost lane, so the reverse vehicle will be naturally guided to the guidance road, and it will be out of the regular lane to prevent collision accidents between the reverse vehicle and the regular vehicle. It has an excellent effect such as being able to do.

Further, according to the reverse traveling vehicle guidance road structure according to the present invention, a lane marking is attached on the boundary line between the traveling lane and the guiding lane, and a boundary pole or a guardrail is attached to a section at a predetermined distance from the end. As a result, it is possible to prevent the reverse-running vehicle from forcibly returning to the driving lane side, which is an excellent effect.

Furthermore, according to the reverse-way vehicle guidance road structure according to the present invention, the reverse-way vehicle travels in the guidance lane at high speed by providing an impact mitigation means at the end of the guidance lane in case of a collision. Even in such a case, it has an excellent effect that the collision accident due to the wall of the dead end can be minimized.

Furthermore, according to the reverse-way vehicle guidance road structure according to the present invention, deceleration of a slope having an arbitrary uphill slope, a continuous uneven road surface, a gravel road, a sharp curve, etc. in a section of a predetermined distance from the end of the guidance lane.

The reverse-way vehicle guidance road structure 10 according to the present invention changes the reverse-way vehicle 21 into a guidance lane 23 different from the regular driving lane 22 on a highway, a one-way road, or the like by using physical and sensory means. The biggest feature is that it adopts a means to prevent a collision accident with a regular traveling vehicle 20 by guiding it safely and surely.
Hereinafter, an embodiment of the reverse-way vehicle guided road structure 10 according to the present invention will be described with reference to the drawings.

The reverse-way vehicle guided road structure 10 according to the present invention is not limited to the examples described below, and is within the scope of the technical idea of the present invention, that is, a structure or a component capable of exhibiting the same action and effect. It can be changed as appropriate within the range of the above.

1 to 5 are explanatory views showing an embodiment of the reverse-way vehicle guided road structure 10 according to the present invention, and FIG. 1 (a) shows examples in the service area SA and the parking area PA. FIG. 1B shows an embodiment on a driving road 11 provided with a median strip 25.
The reverse-way vehicle guidance road structure 10 according to the present invention is basically configured by providing a guidance lane 23 on the right side of the traveling lane 22 with respect to the traveling direction of the regular traveling vehicle 20.

The guidance lane 23 is formed at a portion on the right side of the traveling lane 22 in a direction opposite to the traveling direction and has a predetermined mileage in which the vehicle can travel along the traveling lane 22. The end of the guidance lane 23 is formed at the end 24 so that the reverse-way vehicle 21 traveling in the guidance lane 23 is stopped by the end 24 and cannot proceed further. The structure of the guidance lane 23 is a main component of the present invention, and in Japan where left-hand driving is adopted, the driver who drives the reverse-way vehicle 21 instinctively leaves the leftmost side in the reverse-way driving direction. In view of the tendency to drive in the lane, in other words, the habit of traveling to the right of the traveling lane 22 with respect to the regular traveling direction, the above structural features are adopted.

The end 24 is formed in a dead end shape at the end and the innermost part of the guidance lane 23 so that the reverse driving vehicle 21 cannot proceed in a reverse driving state any more, and is formed in a dead end shape capable of making a U-turn. You can also do it. Regarding the structure at the end of the guidance lane 23, it is conceivable to include an impact mitigation means 27 and a communication means 32, but the impact mitigation means 27 and the communication means 32 will be described later.

The guidance lane 23 is formed by utilizing the space existing on the right side of the traveling lane 22. For example, when it is formed on the approach road of the service area SA and the parking area PA as shown in FIG. 1A, it exists between the driving road 11 and the approach road branched from the driving road 11. Since it is formed by utilizing the space and the speed of the reverse-way vehicle 21 is not so high, it is sufficient that the total length of the guide lane 23 is formed to be about 50 to 200 m. Further, when the guide lane 23 is formed on the driving road 11 as shown in FIG. 1B, it is formed in the space where the median strip 25 or the like between the traveling lane 22 and the opposite lane 22A exists. Therefore, a space in which at least one vehicle can travel is required between the traveling lane 22 and the opposite lane. At this time, since it is assumed that the speed of the reverse-way vehicle 21 is high, it is preferable that the total length of the guide lane 23 is formed to be about 200 to 500 m.

A lane road marking 26 is attached on the boundary line between the traveling lane 22 and the guidance lane 23. The lane road marking 26 is an instruction marking for indicating the boundary between the traveling lane 22 and the guidance lane 23, and is composed of a solid line road marking 26a and a broken line road marking 26b. The marking mode is not particularly limited, such as a solid yellow line, and various solid road markings 26a may be appropriately adopted.

Regarding the road marking 26 for lanes, it is desirable to mark a certain section of the branch point between the traveling lane 22 and the guidance lane 23 with a white broken line as seen at a normal confluence or branch point, and the broken line road. Marking 26b is adopted. By changing the lane road marking 26 at the branch point to the broken road marking 26b, the reverse vehicle 21 is prompted by the branch marking by the broken road marking 26b and is naturally guided from the traveling lane 22 to the guidance lane 23. It will be.

By the way, at the branch point between the traveling lane 22 and the guiding lane 23, in order to guide the reverse driving vehicle 21 from the traveling lane 22 to the guiding lane 23, as shown in FIG. The embodiment attached to is preferable. Since the guide sign 26c is for guiding the reverse-way vehicle 21, the arrow is attached in the direction opposite to the normal traveling direction. At this time, it is preferable that the tip portion of the arrow is marked so as to be located on the guide lane 23 side so that the regular traveling vehicle 20 does not misunderstand the traveling direction or the like when looking at the arrow.

In addition to the solid road marking 26a in the lane road marking 26, it is preferable to attach a boundary pole 30 or a guardrail 31 to a section at a predetermined distance from the end of the guidance lane 23. FIG. 2A shows a case where the boundary pole 30 is attached together with the solid road marking 26a, and FIG. 2B shows a case where the guardrail 31 is attached together with the solid road marking 26a. Is shown. When the boundary line between the traveling lane 22 and the guiding lane 23 is only the solid road marking 26a, it is physically impossible to keep the reverse traveling vehicle 21 in the guiding lane 23, and it is impossible to make a U-turn or change lanes. It is also assumed that the vehicle will jump out to the driving lane 22 side due to such factors, and there is a risk of causing a collision accident with the regular traveling vehicle 20 at that time. Therefore, by attaching a boundary pole 30 and a guardrail 31 together with the solid road marking 26a to the boundary line between the traveling lane 22 and the guidance lane 23, the reverse driving vehicle 21 is surely prevented from jumping out to the traveling lane 22 side. However, it is possible to prevent a collision accident with the regular traveling vehicle 20.

As for the specific structure of the boundary pole 30 and the guardrail 31, the existing boundary pole 30 and the guardrail 31 that function as "guard fences for vehicles" are sufficient. That is, both the boundary pole 30 and the guardrail 31 are a kind of "vehicle protection fence" that prevents damage from a traffic accident caused by a vehicle having a wrong traveling direction deviating from an oncoming lane or a sidewalk outside the road. In the boundary pole 30 formed of a pile-shaped fence, the boundary between the guide lane 23 and the regular traveling lane 22 can be discriminated, and the reverse traveling vehicle 21 is prevented from easily jumping out of the guidance lane 23. Alternatively, a guardrail 31 formed of a long rail plate with a reinforcing rim processing is attached.

As the reverse-way vehicle guidance road structure 10 according to the present invention, an embodiment in which the impact mitigation means 27 is provided at the end of the guidance lane 23 will be described. FIG. 3 shows a configuration of the impact mitigation means 27, and FIG. 3A shows a case where a metal spring damper device 27a is adopted as the impact mitigation means 27. The metal spring damper device 27a is a device having high impact absorption, low cost, and low maintenance cost. By adopting the metal spring damper device 27a as the impact mitigation means 27, the reverse traveling vehicle 21 travels at high speed. Even in the case of a collision with the end of the guide lane 23, the impact is absorbed by the metal spring damper device 27a, and the accident damage due to the collision can be minimized.

Further, FIG. 3B shows a case where the bank wall 27b is adopted as the impact mitigation means 27. The embankment wall 27b has an embankment structure, so that the installation cost is low, such as embankment using on-site soil, and it is possible to install it without discomfort and with cushioning according to the local environmental conditions. By adopting the embankment wall 27b as the impact mitigation means 27, even if the reverse vehicle 21 travels at high speed and collides with the end of the guide lane 23, the natural cushioning property of the embankment wall 27b allows it. The impact is absorbed and the damage caused by the collision can be minimized.

Regarding the specific structure of the impact mitigation means 27, in addition to the metal spring damper device 27a and the bank wall 27b described above, for example, mechanical devices such as a hydraulic damper device and an air bag device, synthetic resin members, and natural rubber. , Mizugo, non-mechanical ones such as a slow-moving road structure that gradually narrows with respect to the traveling direction, and the like can be adopted, and are not particularly limited.

Further, as the reverse-way vehicle guidance road structure 10 according to the present invention, an embodiment in which the deceleration means 28 is formed in the guidance lane 23 can be adopted.

FIG. 4 shows an embodiment of the deceleration means 28.

FIG. 4A shows a case where the guidance lane 23 is formed as an uphill slope 28a as the deceleration means 28. In this way, by making the guidance lane 23 a slope-like 28a, a deceleration force due to gravity is generated by using an arbitrary uphill slope, the reverse-way vehicle 21 naturally decelerates, and the reverse-way vehicle runs backward to the driver. It is possible to safely and surely recognize that the condition is present.

FIG. 4B shows a case where the road surface of the guide lane 23 is formed into an uneven road surface 28b as the deceleration means 28. In this way, by forming the guide lane 23 into an uneven road surface 28b, it is possible to give a continuous running impact to the reverse-way vehicle 21 to suppress the running speed, and at the same time, the driver is in a reverse-way state. It can be recognized safely and surely.

FIG. 4C shows a case where the road surface of the guide lane 23 is formed into a gravel road shape 28c as the deceleration means 28. In this way, by forming the guide lane 23 into a gravel road shape 28c, it is possible to give the reverse-way vehicle 21 a running vibration different from that of the asphalt surface to suppress the running speed, and the driver is in a reverse-way running state. It is possible to make people recognize this safely and surely.

FIG. 4D shows a case where the deceleration means 28 is formed in a collision protrusion 28d in which a flexible pylon is embedded in the road surface of the guidance lane 23. In this way, by forming the guide lane 23 into a collision protrusion 28d, it is possible to apply a gentle contact collision force by the pylon to the reverse-way vehicle 21 to suppress the traveling speed, and at the same time, the driver can be in the reverse-way state. It is possible to safely and surely recognize that there is something.

Further, as the reverse-way vehicle guidance road structure 10 according to the present invention, an embodiment in which the guidance lane 23 is provided with the warning means 29 can be adopted.

In this way, by providing the warning signboard 29a, characters such as "Stop!", "No entry!", And "Reverse road!", Which cannot be seen with the sign in the regular driving lane 20, are displayed on the warning signboard 29a. Then, it is possible to remind the driver of the reverse-way driving through the eyes and to safely and surely recognize the reverse-way driving state.

FIG. 5B shows an embodiment in which a plurality of blinking lights 29b are arranged at predetermined intervals in the guidance lane 23 as warning means 29. By deploying the blinking light 29b in this way, the blinking of the blinking light 29b makes it possible to visually remind the driver of the reverse driving and to safely and surely recognize the reverse driving state.

FIG. 5C shows an embodiment in which a gate-shaped traffic control sign 29c is installed in the guidance lane 23 as a warning means 29. By installing the gate-shaped traffic control sign 29c in this way, characters such as "reverse running!" And "danger!" Are displayed above the windshield of the reverse-way vehicle 21 when passing through the traffic control sign 29c. By displaying the display, the driver can be visually reminded of the reverse driving and can safely and surely recognize the reverse driving state.

Regarding the specific structure of the warning means 29, in addition to the above-mentioned warning sign 29a, blinking light 29b, and traffic regulation sign 29c, for example, visual means such as a warning light and auditory means such as a speaker / siren are also adopted. It is possible, and it is also possible to selectively and superimpose a plurality of different means.

Further, as the reverse-way vehicle guidance road structure 10 according to the present invention, an embodiment in which the communication means 32 is installed in the guidance lane 23 can be adopted.
