![]() If a vehicle collides with an unforgiving object like a wall or tree that doesn’t absorb part of the impact energy, the full force of impact is taken by the vehicle. This helps to reduce the force of impact on the vehicle and its occupants. Some of the impact energy is transferred from the vehicle and its occupants to the barrier. The impact energy is disbursed along the length of the barrier, thereby giving it the necessary crash impact absorption capacity. The entire system works together to absorb the kinetic impact energy of a vehicle collision with the guardrail. Improve driver confidence at night as they provide a visible edge on the side, giving the driver the confidence to stay closer to the yellow or edge line as opposed to the median line, thereby helping to reduce a head-on collision risk.Redirect straying vehicles back to their original drive path upon side impact.Create a strong barrier between hazards and the road.Increase visibility of the road edge and safe travel path.What are the top functions of guardrails?Īs road safety barriers, these act to improve road safety conditions. On the edge of an urban road – to provide an effective barrier between the road demarcated for vehicle traffic and the pavement area demarcated for cycling and foot traffic.On the edge of any section of road where there is a considerable risk of a vehicle colliding with a hazardous object, such as a streetlight, billboard, tree, or a brick-and-mortar structure.Tollbooth off- and onramps – to prevent motorists from driving around tollbooths to avoid having to pay gantry fees.On- and offramp slopes – to prevent straying vehicles from going down the slopes.On the median island between two highways – to prevent motorists from attempting dangerous U-turn actions into the fast lane of the opposite flowing highway.Median of two opposite flowing highways – to prevent accidents from one highway spilling over to the opposite direction fast lane of another highway.Bridge – to prevent vehicles from going over the edge of the bridge into a water source or onto traffic from a road below.Sharp turn in a road – to prevent vehicles from leaving the safety of the road.Mountain pass – to prevent vehicles from going over the edge of a cliff.These safety or traffic barriers are installed at the edge of rural and urban roads, in the medians of two opposite flowing highways, at the on and off-ramps on highways leading towards or away from tollbooths, and on bridges. It provides a safety edge to the end section of the barrier to prevent the sharp edge of the panel from penetrating the body of a vehicle that collides with the end of the barrier. The end of the barrier is buried or fitted with an end terminal, which is a solid plate. If placed in the median of two highways, then the panels are on both sides of the wooden or steel posts. It consists of several components like the W-beam shaped steel panels attached to wooden or steel posts, which are buried into the soil or attached to a hard surface by means of bolts. It’s a type of traffic barrier, specifically designed to protect motorists from direct impact with hazardous objects on the side of the road and beyond the barrier, and to prevent vehicles from leaving the safe travel path. See more information about the Armco barrier here. Read on for more information about this traffic barrier type, including: A guardrail is a type of road safety device, often referred to as a traffic barrier, which is installed at dangerous sections of roads, whether on urban, rural or highway sections.
