Abstract

A method for preventing traffic accident is provided to reduce traffic accident in bad weather condition by forming warning words on a road. Weather information is confirmed by confirming a bad weather condition like a dark mist on a road. A laser beam is irradiated on the road in order to inform warning words of the bad weather condition if the bad weather condition is confirmed. The warning words of the bad weather condition are formed by irradiating the laser beam on the road, are formed in a location corresponding to an eye level of a driver.

Description

{Method for Cars from making accidents in bad weather condition}

The present invention relates to a traffic accident prevention method in a bad weather situation, and more particularly, a traffic accident in a bad weather situation to prevent the accident in advance to warn the driver of the bad weather to slow down in bad weather conditions such as farming (dense fog). It is about prevention method.

At present, the roads of Korea are experiencing bad weather such as dense fog with a visible distance of less than 10 meters, and many traffic accidents occur under such weather conditions.

The representative accident was a 29-day collision on the West Sea Bridge on the West Coast Highway on October 3, 2006. In the traffic accident of the West Sea Bridge, 12 people were killed and 50 people were injured, resulting in property damage that nearly destroyed 29 vehicles. In addition, considering the property damage, such as the inability to use social overhead capital caused by full control of the road due to the accident, the amount will increase to an astronomical amount.

Currently in Korea, warning signs such as fog or deceleration are displayed by using billboards installed in various places of the road, but in the case of heavy fog or heavy rain with a short range of sight, warning signs are not appealed to drivers. It is difficult to expect accident prevention by electric signboard.

The present invention has been made to solve the above problems, and an object thereof is to provide a traffic accident prevention method in a bad weather situation that can give drivers a stronger awareness of accident prevention.

In order to achieve the above object, the present invention,

Confirming the presence or absence of bad weather such as heavy fog on the road; And,

A bad weather warning step of warning bad weather to a driver on the road by injecting a warning phrase using a laser beam on a road where the bad weather is identified when bad weather such as dark fog is identified on a specific road in the weather information checking step; It provides a traffic accident prevention method in a bad weather situation comprising a.

The bad weather warning phase

It is preferable to form a warning sentence at a position corresponding to the eye level of the driver.

More preferably, the warning phrase is scanned to move in the direction toward the driver.

The laser beam is preferably a wavelength of red light of 610 ~ 700nm.

More preferably, the laser beam is scanned using helium-neon.

The weather information checking step,

It is preferably made by a fog sensor installed on the road.

Hereinafter, an embodiment of the present invention will be described.

The traffic accident prevention method in a bad weather situation according to the present embodiment consists of a weather information check step and a bad weather warning step. The most common cause of a large traffic accident is the most dense fog situation with a very short distance, so the following describes how to prevent a traffic accident in a dense fog situation.

The weather information checking step is to check whether a heavy fog occurs on the road.

The weather information confirmation is made by a fog sensor installed in the habitual fog section on the road.

The fog sensor is commercially available, and there are also patented products, so it can be appropriately selected and used.

If it is confirmed by the fog sensor that there is a fog on a particular road will be a bad weather warning.

The bad weather warning is a warning phrase such as "fog attention" or "deceleration" "speed limit 50Km / h" in the direction toward the driver at the position corresponding to the driver's eye level using the laser beam on the road where the heavy fog is identified By injecting a laser beam to move, the driver's speed is reduced by warning the driver of bad weather.

The laser beam allows the driver to use red light, the color of which the driver can feel the strongest sense of alertness, and the wavelength of the red light laser beam is 610 to 710 nm. Since the laser beam using helium-neon is most common when generating the red light, it is most preferable to use helium-neon.

The laser beam is visible to the human eye by light scattering. In the case of a dense fog or the like, there are a lot of water vapor particles in the air, and the light is scattered by the water vapor particles to be visible to the human eye.

Since the laser beam is visible to the driver's eyes by forming an image on water vapor regardless of the visible distance, the laser beam is easily visible to the driver's eyes regardless of the visible distance caused by the fog. In the case of using a signboard as in the related art, when the visible distance is short, the discernible section is also short, and at high speed, the visible time of the driver is very short, so that the identification is almost impossible. In addition to being able to identify at very long distances, the laser beam is virtually invisible even when scanning at the driver's eye level, and only light is scattered by water vapor in the air, so even if the vehicle passes the warning letter. There is no damage to the vehicle. On the other hand, in the case of using the signboard, in order to prevent the collision between the signboard and the vehicle is installed in a higher position than the vehicle with the highest height of the vehicle running on the road, the identification is less distinguished, in the case of the present invention, the warning statement is at the eye level of the vehicle driver By scanning on, it should be seen that the discriminating power is superior to the conventional electronic display board.

In addition, when warning signs are injected in the direction of approaching the driver in the air, the alert feeling felt by the driver becomes incomparable with warning signs such as "fog warning" that appears on the electronic signboard. You can expect the effect.

Even if the warning text continues to be injected into the air, the vehicle proceeds, so the warning text feels as if it is moving toward the driver, which makes the driver feel a great sense of alertness. You can expect it to get bigger.

In the above, an embodiment of the case where a heavy fog occurs on the road has been described, but even when the visible distance is limited due to a fog situation or heavy rain, which has a relatively long viewing distance, the warning message may be scanned using a laser beam. Even in this case, the present invention can achieve the desired object.

Although the preferred embodiment of the present invention has been described above, the technical idea of the present invention is not limited to the described embodiment, and traffic accidents of various types of bad weather conditions within a range that does not violate the technical idea of the present invention. Can be embodied as a preventive measure.

As described above, the present invention has an object to provide a traffic accident prevention method in a bad weather situation that can give drivers a stronger awareness of accident prevention.
