Abstract

To provide a head-on collision accident prevention device having both effects of preventing vehicles from entering an intersection without stopping properly, and of preventing a reversely running vehicle from entering, so as to solve the problem in which precious lives have been lost in the past due to occurrence of a tragic head-on collision accident by a driver entering the intersection without confirming a vehicle running in a crossing manner by careless driving or the like caused by an oversight of a temporary stop sign.SOLUTION: It is so constituted that a running limitation pole 11 responds to a vehicle stop board 13 in a movable manner via an arm 21, a link 22, and an operation bar 23. The running limitation pole 11 is stored on a road surface by temporarily stopping a vehicle 10 on a vehicle stop board 13, and thus passage of the vehicle 10 becomes possible, and the passage to an intersection becomes possible.SELECTED DRAWING: Figure 2

Description

[Technical field]

[0001] The present invention relates to a device for preventing head-on collisions caused by vehicles not stopping temporarily. [Background technology]

[0002] In the past, there have been many cases where tragic head-on collisions have occurred and precious lives have been lost due to drivers missing stop signs or driving carelessly and entering intersections without checking for vehicles crossing the intersection. However, these responses, such as making sure to stop at the correct time, always checking road signs, and not being overconfident even on priority roads, do not serve as a concrete deterrent in that they only encourage individual drivers to be careful. In reality, the measures are limited to measures to reinforce awareness, such as by increasing the visibility of road signs.

[0003] The main ones disclosed include detecting the approach of a vehicle to an intersection and encouraging the vehicle to stop temporarily by lighting up an illuminator installed at the stopping position (Patent Document 1), detecting vehicles and bicycles on the priority road with a sensor and transmitting that information via communication to drivers of vehicles on non-priority roads to warn them (Patent Document 2), warning drivers of bicycles and vehicles on the intersecting road by lighting up an illuminator when a sensor detects a bicycle approaching an intersection (Patent Document 3), and sending a vehicle control signal according to the status of the traffic light to an on-board sensor chip via a sensor chip buried in the road surface, controlling the starting and stopping of the vehicle (Patent Document 4).

[0005] However, in Patent Documents 1, 2, and 3, while they may be effective at night, during the day when the surroundings are bright and busy, the light and audio warnings are only intended to alert drivers who are driving conscious- ly, and their effect in preventing drivers from overlooking signs or getting into head-on collisions is limited. In addition, Patent Document 4 employs compulsory vehicle control based on external information, and is more effective at preventing head-on collisions than other methods, but requires infrastructure development and installation of the system in vehicles, and the scope of the deterrent effect is limited. The present invention is different in that it is a compulsory device that prevents vehicles from entering an intersection without stopping temporarily, which has the effect of deterring drivers from overlooking signs or carelessly passing through, and because it is only applied to the road side, it is expected to have an effect of deterring head-on accidents for all vehicles passing through the intersection. As a result, compared to Patent Documents 1, 2, and 3, this has the effect of preventing drivers from overlooking signs and causing head-on accidents. As a result, compared to Patent Document 4, it is expected that the effect of preventing head-on collisions can be achieved for all vehicles passing through the intersection.

[0006] The problem that this invention aims to solve is to provide a device that prevents drivers from missing signs and inadvertently causing head-on collisions by forcibly stopping all vehicles passing through an intersection without equipping the vehicles with a system or other device. In addition, since this device allows vehicles traveling in the correct direction to pass through the road by stopping, it also has the effect of preventing vehicles traveling in the wrong direction from passing through. [Means for solving the problem]

[0007] The head-on collision prevention device of the present invention according to claim 1 is disposed just before an intersection of intersecting roads, Failure to stop due to overlooking a stop sign or careless driving The intersection The above-mentioned method can protect the occupants and drivers of vehicles traveling on priority roads by forcibly preventing the vehicles traveling on non-priority roads from entering the road. road Traffic control poles installed in And the above Travel restriction pole is moved in response to the stop plate, and the Driving on non-priority roads When the vehicle stops, the weight of the vehicle increases. Travel restriction pole is stored on the road surface, Driving on non-priority roads The vehicle is Travel restriction pole The structure allows traffic to cross the intersection and reach the intersection.

[0008] The head-on collision prevention device of the present invention according to claim 2 is configured to prevent a wrong-way vehicle from passing through the intersection. Travel restriction pole The present invention is characterized by having the following. Effect of the Invention

[0009] According to the head-on accident prevention device of the present invention as set forth in claim 1, head-on accidents can be prevented by preventing vehicles that do not stop due to overlooking a stop sign, careless driving, etc. from entering an intersection.

[0010] According to the head-on accident prevention device of the present invention as set forth in claim 2, since vehicles traveling in the wrong direction are prevented from entering a one-way road, it is expected that accidents caused by vehicles traveling in the wrong direction can be prevented.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS EXAMPLES

[0012] An embodiment of the head-on collision prevention device of the present invention will be described with reference to the drawings. As shown in Fig. 1, the travel restriction pole 11 is configured to move in response to the vehicle stop board 13 via an arm 21, a link 22, and an operating bar 23. In a normal state, since a vehicle 10 is not stopped on the vehicle stop board 13, the travel restriction pole 11 stands upright and vehicles cannot pass through. Vehicles from the opposite direction cannot pass through either. A reflector 12 is attached to the travel restriction pole 11 to improve visibility from the vehicle 10.

[0013] 2 shows a state in which the vehicle 10 is temporarily stopped on the vehicle stop board 13 and the travel restriction pole 11 is stored on the road surface. In anticipation of a case in which a foreign object is caught in the travel restriction pole 11 when it is stored on the road surface, a pinch prevention spring 24 is built into the operating bar 23 to protect the foreign object from being caught in the travel restriction pole 11. The load of the vehicle 10 applied to the vehicle stopping board 13 pushes the hydraulic cylinder 25, and the hydraulic pressure is transmitted to the hydraulic control unit 26. When the vehicle 10 subsequently moves off the vehicle stopping board 13 and the load of the vehicle 10 is removed, the hydraulic pressure is returned from the hydraulic control unit 26 to the hydraulic cylinder 25. The hydraulic control unit 26 can set the time arbitrarily depending on the direction of hydraulic pressure application, so that the travel limiting pole 11 is set to the road surface within a few seconds equivalent to the temporary stop time after the load of the vehicle 10 is applied to the vehicle stop board 13, and then the travel limiting pole 11 returns to the normal upright state more than ten seconds after the load is removed.

[0014] <<Modifications>> In the modified example shown in FIG. 3, the travel limiting pole 11 is inserted and removed perpendicularly to the road surface, so there is no need for the anti-pinch spring 24 since there is no risk of foreign objects getting caught in it. The structure also does not require the link 22 or the operating bar 23, making the structure relatively simple.

[0015] <<Variation 2>> Variation 2 shown in Fig. 4 is intended for application to intersections where the volume of bicycle and pedestrian traffic is low and where it is necessary to make two temporary stops, such as in alleys with poor visibility. The travel limiting pole 11 in Fig. 1 is replaced with a travel limiting gate 14, and since there is no concern about foreign objects getting caught, the anti-pinch spring 24 and link 22 are not required, as with the variation in Fig. 3, making the structure relatively simple.

[0016] 5 shows the operating state of the modified example 2. The state is shown in which the vehicle 10 is temporarily stopped on the vehicle stop board 13 and the travel limit gate 14 is stored on the road surface. FIG. 6 shows the operating state of the second modified example, in which the vehicle 10 is temporarily stopped for the second time on the travel restriction gate 14.

[0017] <<Variation 3>> 7, the vehicle sensor 15 is laid on the road surface to detect the presence or absence of a vehicle, and once the vehicle 10 has reliably moved away from this location, hydraulic pressure is returned from the hydraulic control unit 26 to the hydraulic cylinder 25, and the travel limiting pole 11 returns to the upright state. This modification 3 is a configuration for the case in which it is assumed that the vehicle 10 will not move from this location after stopping temporarily, but will remain there for some reason.
