[0002] Anti-collision guardrails are important facilities that are essential to ensure safe, comfortable and fast operation of highways. As the proportion of large trucks increases, traffic accidents in which vehicles collide with guardrails and run off the road or bridge, causing casualties, also occur from time to time. At the same time, traffic accidents occur on high-risk sections such as highways crossing railways, bridges, near reservoirs, and oil depots. Once a vehicle runs out of the guardrail, it is easy to cause a secondary accident, and it may even directly collide with the main structure of the building facilities outside the guardrail, causing huge losses, which has a major impact on normal traffic operations and the safety of people's production and life.
