Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a roadside accident prevention method in which a large number of line-of-sight guide signs are installed at intervals on a roadside protective fence.

(Prior art) Traffic signs and sight guide signs are installed on roads to inform drivers of the road structure and alignment in the direction they are traveling, thereby alleviating drivers' worries and anxiety. Reducing the degree of fatigue is an essential requirement for ensuring smooth traffic and increasing traffic safety.

By the way, the roadside visual guide currently in use is a reflective material such as glass or plastic called a delineator, which is attached to a metal fitting.
Directly along the road, a large number of line-of-sight guide marks are installed at certain intervals on protective fences such as guardrails and guide lobes, roadside green stones in tunnels, and railings on bridges or elevated bridges. The way they are installed is focused solely on visual guidance, similar to center lines and lane markings on roads.

However, there are many cases in which recently constructed highways have drainage channels with semicircular cross-sections, called roll gutters, located on the road side of the median barrier.

(Problem to be Solved by the Invention) In such a case, during the snowy season when the road surface is covered with snow, the road surface and drainage channels have a uniform planar shape due to the snow, and the lane marks are As the snow obscures the view and only the protruding protective fence is visible, many cars drive close to the protective fence, drop their wheels into the drainage canal, have their wheels slip on the shearbed snow, and are unable to exit the drainage canal onto the road. One of the major causes of traffic congestion is one that I often see.

(Means for Solving the Problems) In view of the above-mentioned current situation, the present invention provides a base for fixing line-of-sight guide marks made of elastic material at a required interval on a protective fence installed along the road side. is attached and fixed to each of the base parts, and the reflector part at the tip of the arm rod, which is fixed on the base side to each of the base parts and arranged in a horizontal arm tree shape with respect to the protective fence, reaches near the construction limit on the road. This is a method for preventing accidents on the road side, which is characterized in that the line guide sign made of elastic material can be used for line guidance and for indicating building limits.

(Function) According to the roadside accident prevention law according to the present invention,
The reflector part for guiding the line of sight in the line-of-sight guiding sign made of elastic material is fixed horizontally with arm rods to the protective fence installed along the road side. Because it has reached the vicinity of the construction limit between the drainage canals, etc. located along the
During normal times, except when it snows, it works like delineators installed on roadways to date, eliminating driver stress and anxiety, reducing fatigue, ensuring smooth traffic flow, and increasing traffic safety. The driver is informed of the structure and alignment of the road in the direction of travel, and when it snows, the reflector for guiding the line of sight is installed at approximately the same height as the protective fence, so it is easy to see from a place with good visibility. In place of lane markings, etc., the system not only informs the driver of the structure and alignment of the road in the direction of travel, but also clearly informs the driver of the approach limit position to a drainage ditch on the roadside that is no longer visible due to accumulated snow. It became possible to do so. In addition, because the main body of the line-of-sight guide is made of elastic material and can be bent, even if a car or other vehicle were to drop its wheels into a drainage ditch or the like and come into contact with the line-of-sight guide, it would not cause damage to the vehicle body. There is no risk of injury or personal injury.
