A crash barrier street, also known as a crash barrier or guardrail street, refers to roadways equipped with crash barriers designed to enhance safety by preventing vehicles from veering off the road or colliding with hazardous objects. These barriers, typically made of metal, concrete, or other durable materials, are strategically placed along the edges of roads, bridges, and in areas with high accident risk. They absorb and dissipate the energy of a collision, reducing the severity of accidents and protecting both vehicle occupants and pedestrians. Crash barriers are crucial for minimizing the impact of accidents and improving overall road safety, particularly in areas with sharp curves, elevated sections, or near obstacles
