Highway construction work is inevitable, along with safety concerns and well-being of workers, pedestrians, and possible vehicle accidents. Traffic barriers are essential tools to ensure safety by controlling traffic flow in road construction zones and in many other situations where protection involves ingress and egress of vehicles and people. Here is a review of how different types of traffic barriers functions.
Temporary Barriers (Portable)
These safeguard traffic against hazards in construction zones. As the conditions in the roadworks changes, these barriers can be moved since they are portable. Two common types of barricades that fall in this category are temporary concreate and water-filled barriers. Concrete barricades have several advantages. They are affordable, freestanding, and bolted, and they provide a high level of containment. On the other hand, steel or water temporary barriers are mostly used on short-term projects for ease of use and relocation. However, they do not provide the level of protection as the concrete barriers.
Impact Deflection Barriers
This type of barrier is used to deflect moving vehicles, so they keep moving in their original line of travel. An excellent example of an impact deflection barrier is the guard rails. It is meant to form a safety barrier to protect motorists who may have drifted off the road. If a vehicle is slipping off the way, the best option is for the car to come to rest unimpeded. In a few cases, the impact causes the car to lose control, penetrate the barrier, or cross over the wall. The application of this barrier varies depending on the application, such as on a bridge. A good example of this type of barrier is guard rails.
Impact Absorbing Barriers
Prevention is always the best cure! It may be hard to prevent motorists from having accidents, but preventing them from causing more damage is much simpler. Impact-absorbing barriers are meant to do two things. First, they absorb the shock and, secondly, stabilize the vehicle upon impact. They automatically reduce the vehicle's speed and minimize the chances of it spinning out of control, causing a pile-up. Simple types of impact-absorbing barriers range from post or cable, concrete walls, to live plants.
Impact Resistant Barriers
These barriers can significantly reduce or stop the forces of a vehicle's impact. They typically used to prevent a fixed structure or pedestrians from vehicular damages. A common barrier type that falls in this category is a bollard. It is a sturdy, short vertical post, installed to control road traffic to prevent ram-raiding and vehicle ramming attacks.
The purpose of any traffic barrier is to create a safe environment that eliminates the likelihood of accidents and injuries. So, the correct installation of these barriers is essential, as well as the right choice of the barricade that fits your specific needs. This is only possible if you work with a trusted supplier of road safety products to ensure that the safest viable option is selected.
