As shown in FIG. 2 , the first blocking part 10 of the height limiting structure 100 of the present invention is installed at the farthest position from the access road of the facility 1 , and a hologram is incident on the road to be the same as the facility 1 . It creates the virtual facility 2 of the shape and plays a role of guiding so that the driver can voluntarily determine whether to enter the facility as the driver indirectly experiences the passage of the virtual facility.

On the other hand, the first blocking unit 10 may induce a virtual experience by injecting a hologram for all vehicles passing through the section, and the vehicle or height exceeding the allowable height while sharing information with the detection sensor 24 A hologram may be incident only on an ambiguous vehicle to induce a virtual experience. For example, the detection sensor 24 sequentially and quickly measures the height of the vehicle body entering the virtual facility 2 and the loading height of the cargo in the case of a cargo vehicle, and based on the measured information, the vehicle moves to the allowable height of the road. It is quickly determined whether or not has been exceeded, and the determined information is immediately transmitted to the first blocking unit (10).

The first blocking unit 10 immediately recognizes a vehicle exceeding the height with the vehicle information provided by the detection sensor 24, and operates a hologram to image the vehicle in accordance with the speed and location of the vehicle entering the virtual facility 2 to mutually Provides a scene in which the facility is gradually damaged by the collision. In addition, the speaker 13 also operates at the same time to provide a collision sound according to the image to awaken the driver's awareness of the collision with the facility 1 and guide the prohibition of further entry.

However, when a vehicle exceeding the height ignores the warning of the first blocking unit 10 and enters the facility 1 due to driver negligence such as drowsy driving, negligent driving, or vehicle defects such as brake failure, the second blocking unit 20 ) guides the vehicle to stop running once more.

The second blocking unit 20 measures the height of the vehicle entering the first blocking unit 10 through the detection sensor 24 and provides information to the first blocking unit and the indicator light 30, and limits the height By inducing a direct collision with the bar 23, it strongly appeals to stop driving.

In spite of this impact, when an over-height vehicle moves to the facility 1, the indicator light 30 operates a warning light, a siren, and an electric sign to provide visual and auditory traffic restriction guidance, and at the same time information about the vehicle's excess height The driver information registered in the vehicle and the information passed through the first blocking unit 10 and the second blocking unit 20 are transmitted to the road traffic management office to guide field personnel for on-site control and accident management. .

On the other hand, the indicator 30 is equipped with a terminal proximity sharing structure including Wifi or Bluetooth or NFC by itself to ignore the control of the first and second blocking units 10 and 20 and enter the vehicle navigation or the driver's terminal A more convenient road environment is established by guiding the circulation of road traffic.

The road guide device of the present invention configured as described above installs a height limiting structure in order to prevent a collision accident of a vehicle entering a road having a limited height from the ground, such as a road or a tunnel or an underground parking lot that limits the overloaded amount of cargo. The height limiting structure uses various detection sensors and holograms installed on each standing stand to induce the first blocking unit to implement a virtual facility on the road to detect the exterior information of the vehicle entering and to induce a virtual collision experience. By judging whether or not to allow entry prior to a collision, and only to the vehicles that are judged not to be allowed to enter, an entry prohibition guide is delivered, thereby preventing accidents in which the vehicle collides with the height limit bar in advance, creating a comfortable road environment as well as safety for the driver. can do.

In addition, even though the detection sensor delivered an entry impossibility guide, for vehicles that entered the vehicle ignoring it and collided with the height limit bar, a bell and a warning light with a warning sound installed on the height limit bar re-deliver an audible or visual warning of impossibility to enter the road. It is possible to prevent large-scale accidents in advance due to collisions between upper structures and vehicles.

In addition, before the vehicle exceeding the allowable height reaches the facility, on-site personnel are dispatched to deliver the final impassable notice to induce collision accident prevention once again, and in the event of an accident, the personnel who have been dispatched to the site in advance to solve the accident immediately As a result, it is possible to secure driver safety and quickly create a pleasant road environment.
