In the present times, road transport and traveling is the main and most pursued option for commuting. This certainly has its own benefits of flexible and well-controlled travel. However, roads can be rather dangerous when it comes to certain speedy curves and difficult terrains like mountains, hills or lakesides, etc.
As these places tend to be a host of various accidents, crash barriers have become a necessity. They are placed for the prime motive of preventing the accidents from happening or getting any worse in such areas. Here are some of the different types of barriers to prevent a crash.
Flexible Barriers : These barriers are placed as a primary line or attempt of defense against the accidents. Flexible style barriers basically include Metal Beams and corrugated rail systems guided with weak posts. They are designed in a way to deflect all the objects coming towards them. They have the potency to manage the impact intensity with the tension that exists between two attachment points between the barrier pillars.
Semi-rigid : As the name suggests, these barriers have more deflective energy than flexible ones. They prominently include guide rails with box beams, corrugated rail guides, etc. These barriers manage the impact energy with the deformations suffered by the metal at the point of contact. However, being less flexible and more rigid, they do not deflect the vehicle back to the tracks.
Rigid Barriers : These barriers are constructed with reinforced concrete. Such a structure will only deflect a small part of the impact energy back while the rest will ensure that it becomes parallel to the track on which it was moving. These are very protective of hazards and are predominantly used in high mountainous regions alongside steep valleys.
