According to incomplete statistics, more than 50% of accidents on highways are caused by vehicles hitting guardrails. Traffic accidents are often unavoidable, but the damage of the accident can be minimized. A Korean company called ETI has designed a rotating anti-collision guardrail that claims to be able to save many lives in many traffic accidents.
There is nothing special about it just from looking at the photos. There are just yellow cylinders installed on the guardrail. These cylinders can be rolled. When a car hits a car, the effect is as shown below:
When the car hits the guardrail, the cylinder will roll, effectively converting the impact force into forward momentum. , the harm to the driver can also be minimized. Even large-tonnage trains are no problem, and the buffering effect is not weak at all.
You can look at the effect from God’s perspective:
The roller uses EVAMade of polyurethane composite material, this material has the characteristics of elasticity, anti-collision and wear resistance, good recovery effect, anti-corrosion, anti-UV aging, weather resistance, luminous and other advantages, and its service life can be up to 10 years. . It can effectively protect the people in the car when an accident occurs.
At present, this material has applied for 22 invention patents and is already being used in the United States, Japan, South Korea and other countries. It is said that some places in China have also begun to test and use it. However, the cost of materials is not low. Some relevant people have pointed out that when the car hits the guardrail, it will bounce back to the center of the road, affecting other vehicles. It is still unclear whether it can be popularized in the future.
