Helpful Metal Barriers for Prevention of Road Mishaps and Collisions

We can prevent many road accidents from the use of traffic barriers. Usually, these accidents are caused by the run of the road vehicles colliding with each other or with obstacles by the roadside. At times, these vehicles veer off the road and roll down steep slopes. While negotiating steep curves, they lose their traction on the road and slip laterally into ditches and suffer irreparable damage.

How does a barrier help?

A right choice of barrier can reduce the risk of damage. It can reduce the severity of the damage to a great extent. There are a number of barriers that come into play such as metal section highway crash barrier, W beam highway crash barrier, Double W beam metal crash barrier, single face double metal crash barrier, and so on. You can get the choice of your barrier from the Metal Beam Crsh Barrier Exporters in Kolkata. These are made according to the Ministry of Transport & Communication specificatio
IRC: 119 and NCHRP: 350.

The first use of barriers in on hilly terrain where there is an increased risk of running off the road. It is also used in high-speed highways where there are chances of drivers losing control of their vehicles at high speed. We can see it in U-tu
s especially in elevated zones and on roads along elevated embankments where there is a good chance or rolling down the steep slope.

Testing is done first

The usual work done by barriers is to minimize the damage and reduce injury to its occupants; it may also have another functional aspect. We should only install a barrier when the damage due to collision with another vehicle is greater than that of the collision of the vehicle with the barrier itself. For this reason, the barriers undergo extensive crash testing before being deployed.

Other likely places where they deploy this safety feature include school yards, residential areas, and pedestrian zones. You also find them at bridge ends, near signs by the roadside, at drainage crossings and culverts, and on steep slopes. The type and size of the barrier are calculated according to the intensity, type, and size of the traffic on the road. Also, a clear zone is calculated to see whether it will stop the vehicle from straying off the road. This is a lateral distance from the road’s edge to the barrier and the distance back after impact back to the road. You get more details of this from the Metal Beam Crash Barriers Suppliers If the clear zone is sufficient, then the vehicle manages to come back to the road.

Common places of use

The most common barrier is the median barrier that we find in the middle of a double carriageway road. We have traffic coming from both sides of this road and so these barriers are designed to withstand shock from both sides. The work done by this is to prevent the vehicle from coming down the opposite stretch to jump the median and collide with the oncoming traffic.

We also have a classification of barriers according to their stiffness. One is the flexible barrier that is usually a weak post corrugated guide rail system or a chain link. Semi-rigid barriers include box beam guide rail and rigid barriers are W metal crash beams.
