Road
traffic intensity is constantly increasing and increase in speed limits is
leading to an increase in the number of accidents. This leads to improved road
infrastructure system. Road barriers are one of the ways used to prevent
vehicles colliding with each other and to reduce the severity of the accidents.
By which the number of accidents occurring will also be reduced. Road barriers
also help in isolating traffic, preventing other roadside objects, prevent
animals from disturbing the traffic etc.
These
barriers are completely based on the technical requirements. The primary goal
of the barrier is to restrain vehicles from a collision and slowly dissipate
kinetic energy as much as possible to the barrier surface. This would control
the speed the vehicle colliding and thus reduce the damages of the accident. In
the same time, it also saves the lives of the public who are not responsible
for the accident.
In
case of collision, the barriers should not be loose from the supports and be
thrown upon the roadway where it may again collide with another vehicle. So
depending on the hazard level of the road, barriers should have different
prevention levels.
Containment
levels:
Barrier
prevention level is also known said as barrier containment level. It can range
from low to very high. The barrier containment levels are decided by the
factors like driving speed, traffic intensity, terrain, and other criteria. If
barriers are required for temporary safety, the containment levels of the barriers
can be reduced as required, for example, low containment level barriers are
required for sites for roadside works. Concrete barrier’s composition can be
done making it resistant to impacts and absorbing part of vehicle energy.
Barriers’ safety criteria were developed primarily for cars and heavier
vehicles where two-wheelers were not into consideration.
Report:
But
later surveys revealed a report that a motorcyclist is 15 times more likely to
be killed than people in a car. During collisions there are number more of
fatalities. sSo it is important for the structure of the road barriers to
absorb energy as much as possible.
A
road barriers’ quality can save the lives of thousands of people by reducing
the number of accidents and the severity of the accidents. Thus opting for
high-quality road barriers is more important task here. One of the high-quality
road barrier manufacturers is the PolyconBahrain. They are the manufacturers of
a wide range of road barriers. Check out the link for further information:
