CRASH BARRIER Meaning and
Definition
-
A crash barrier, also known as a guardrail or safety barrier, is a device designed to provide protection and enhance safety on roads and highways. It is a physical barrier made of a variety of materials, such as steel, concrete, or wood, and is strategically installed along the side of a roadway or in the median to prevent vehicles from leaving the roadway and colliding with obstacles, such as ditches, trees, or other vehicles.
The primary purpose of a crash barrier is to absorb the impact energy of a vehicle during a collision, thereby reducing the severity of injuries to occupants and minimizing damage to the vehicle. Crash barriers are typically composed of a series of posts or supports, connected by strong horizontal beams, which are designed to flex and deform upon impact. This deformation absorbs and dissipates the kinetic energy, effectively redirecting and containing the vehicle within the roadway.
Depending on the specific requirements and traffic conditions, different types of crash barriers can be deployed. These include guardrails, which are commonly used on highways and consist of steel barriers that are often corrugated or finned to enhance their energy-absorbing properties. Cable barriers, composed of steel cables, are also employed to deflect and restrain vehicles. Additionally, concrete barriers are utilized for higher impact resistance and protection against large vehicles.
Crash barriers play a crucial role in preventing accidents, reducing the severity of injuries, and saving lives. They are an essential feature of road infrastructure, providing a physical barrier between vehicles and potential hazards, and helping to maintain safe and efficient travel conditions for all road users.

Etymology of CRASH BARRIER
The word "crash barrier" is composed of two elements: "crash" and "barrier".
The term "crash" originated from the Middle English word "craschen" meaning to shatter or break into pieces. It ultimately derived from Old French "craissir", meaning to break or shatter, which came from Latin "crassus", meaning thick or solid. Over time, "crash" came to refer to a sudden, violent collision or impact.
The word "barrier" traces back to the Middle English term "barere" or "barriere", which originally referred to an obstacle made of bars, such as a gate or a fence. "Barere" came from the Old French word "bariere" with the same meaning. It is believed to have further derived from the Frankish word "baro" or "bara", meaning beam or bar.
