Crash Cushion Barriers – What Are its Uses?

Have you ever noticed those cushion-like barriers along the roads? They are known as the Crash Cushion barriers!

They might not get much attention, but they play a huge role in keeping us safe. 

Crash cushion barriers are like silent safety equipment, quietly standing guard to reduce the impact of accidents.

Let’s take a closer look at why these barriers are so important for keeping drivers safe on the roads

What are Crash Cushion Barriers?

Crash cushion barriers are also known as impact attenuators or crash attenuators. They are safety devices installed on roads and highways to reduce the severity of vehicle collisions.

These barriers are designed to absorb kinetic energy from a vehicle that collide with them during the accident. This thereby decreases the impact forces on the vehicle occupants and minimizes the damage to the vehicle itself.

The idea is to create a structure that crumples or deforms in a controlled manner when a vehicle crashes into it, dissipating the vehicle’s kinetic energy and reducing the force exerted on the vehicle and its occupants.

What are Crash Cushion Barriers Made of?

These barriers come in various forms and designs but generally consist of materials that compress or deform upon impact. Some crash cushions use a series of barrels filled with sand or water, while others employ specially designed metal structures or composite materials.

Crash cushion barriers are strategically placed in areas with a higher risk of collisions, such as the ends of concrete barriers, bridge supports, toll booths, and other locations along highways and roads. They improve overall road safety by mitigating the severity of crashes and protecting drivers and passengers from more serious injuries.

Uses of Crash Cushion Barriers: 

Now let’s move to talk about the uses of Crash cushion barriers. Crash cushion barriers serve several crucial purposes in ensuring road safety:

Collision Energy Absorption:

They are designed to absorb and dissipate the kinetic energy of a vehicle during a collision. By doing so, they reduce the severity of the impact, minimizing injuries to vehicle occupants and damage to the vehicle itself.

Protecting Fixed Objects:

Crash cushion barriers are often placed near fixed objects like bridge supports, toll booths, and concrete barriers. They act as a protective barrier, reducing the chances of a vehicle hitting these immovable structures directly.

Preventing Secondary Collisions:

When a vehicle collides with a crash cushion barrier, secondary collisions can be prevented by redirecting or slowing down the vehicle in a controlled manner. This reduces the risk of additional accidents involving other vehicles.

Improving Road Safety:

Crash cushions improve road safety. By mitigating the impact forces during a crash, these barriers contribute significantly to overall road safety. They are strategically placed in high-risk areas to minimize the severity of accidents and protect drivers and passengers.

Reducing Property Damage:

In addition to safeguarding human lives, crash cushion barriers also help minimize property damage. It imposes impact forces and prevents vehicles from hitting nearby structures or obstacles.

Overall, the primary uses of crash cushion barriers revolve around mitigating the impact of collisions, safeguarding lives, reducing injuries, and enhancing the overall safety of roads and highways.

Know the Benefits Of Crash Cushions:

Crash barriers offer several crucial benefits as safety measures for motorists and pedestrians, serving beyond simple roadside fences. Engineered meticulously, they provide six major advantages:

Enhanced Road Safety:

These barriers safeguard traffic from potential hazards like steep slopes and sharp bends, effectively preventing rollover crashes. By keeping vehicles from entering opposing lanes, they significantly reduce the risk of severe accidents.

Collision Impact Reduction:

During highway collisions, vehicles often veer sideways. Crash barriers intercept and redirect vehicles, minimizing damage by allowing the vehicle to regain its trajectory onto the road.

Low Maintenance Requirements:

Compared to other road safety barriers, crash barriers demand minimal maintenance. Their robust engineering enables them to endure high impacts without frequent upkeep.

High Visibility:

Constructed from highly visible materials like metal, crash barriers ensure visibility even in low-light conditions, such as during nighttime. This visibility plays a critical role in accident prevention and keeping vehicles on the road.

Strength and Longevity:

Crafted for toughness, crash barriers withstand harsh weather conditions and can endure for over 30 years, exemplifying durability and long-term reliability.

Design Versatility:

Crash cushions come in various designs, making them adaptable to different road configurations and traffic conditions. They can be tailored to suit specific needs and installed in a range of locations to enhance safety.

Types of Cushion Barriers: 

There are two primary types of crash barriers used on highways, categorized by their shape, size, and components: the W-beam and Thrie-beam Crash Barriers. These are further classified into:

  • Single-sided crash barriers
  • Single-sided double-beam crash barriers
  • Thrie-beam single-sided crash barriers
  • Double-sided single W-beam barriers
  • Single-sided Thrie-beam crash barriers with end sections
  • Single-sided crash barriers with end sections

How to select the Best Crash Barriers?

Consider the following factors when choosing the most suitable crash barrier:

  • Installation needs
  • Barrier flexibility
  • Terminal treatment of the barrier
  • Necessary length
  • The transition between different barrier types

Furthermore, it’s crucial to ensure that the chosen barriers adhere to international specifications and are crafted from high-grade raw materials to ensure superior strength and stability.

Eastern Highway – Your Choice To Get the Best Cushion Barriers: 

Wrapping up this exploration of crash cushion barriers, it’s evident that these safety measures play a pivotal role in road safety, protecting lives and minimizing damages in the event of collisions.

Choosing the right barrier not only ensures immediate safety but also reduces maintenance needs and enhances overall road safety for years to come.

Frequently Asked Questions:

What is the traffic barrier crash cushion?

A traffic barrier crash cushion is a safety device designed to absorb the impact energy of a vehicle during a collision, minimizing damage to both the vehicle and the barrier.


What is the purpose of a crash cushion?

The purpose of a crash cushion is to protect drivers by reducing the force of impact in a crash, helping to prevent serious injuries and vehicle damage.


What is the role of the cushion barrier?

The role of the cushion barrier is to act as a buffer between vehicles and fixed objects or hazards, redirecting or absorbing crash energy to reduce the severity of an accident.


What are the two types of crash cushions?

The two types of crash cushions are redirective and non-redirective cushions. Redirective cushions deflect vehicles back into their lanes, while non-redirective cushions stop vehicles upon impact.
