Crash Attenuation

Crash attenuation is an integral component of road safety, aiming to minimize the severity of collisions and safeguard both motorists and infrastructure. In Canada, crash attenuation is stringently regulated to uphold the highest safety standards on our roads. In this article, we’ll explore the various types of crash attenuators, their testing levels, and the offerings of Barricades and Signs, a frontrunner in the industry.

Types of Crash Attenuators

Temporary Crash Cushions: Primarily used in construction zones or temporary traffic setups, these are designed for easy installation and removal.

Truck-Mounted Attenuators (TMA): Affixed to the rear of work vehicles, TMAs absorb the impact from errant vehicles, thereby protecting workers and equipment.

Permanent Crash Cushions: These are stationed at fixed locations, like the ends of guardrails or concrete barriers, and are built for durability and long-term protection.

Redirective Crash Cushions: These attenuators are crafted to safely steer an errant vehicle away from potential hazards rather than merely absorbing the impact.

Permanent Barriers

Permanent barriers are stationary structures installed to prevent vehicles from veering off the road or into oncoming traffic. Made from robust materials like concrete or steel, they are designed to withstand significant impacts and are commonly found on highways, bridges, and around hazardous zones.

Our Permanent Barriers

Temporary Steel Barriers

These barriers offer a flexible solution for areas undergoing construction or temporary traffic changes. Made of steel, they provide robust protection but can be relocated as required. Their modular design allows for easy assembly and disassembly.

Impact Attenuators

Also known as crash cushions, impact attenuators are devices placed in front of potential road hazards. They absorb the energy from a vehicle collision, reducing the severity of the impact and preventing more significant damage or injury.

Guardrails

Guardrails are a fundamental element in the road safety infrastructure, designed to prevent vehicles from veering off the road, especially in dangerous or high-speed areas. They act as a physical barrier, absorbing and redirecting the impact energy during a collision, thereby minimizing the potential for severe injuries and fatalities.

Guard Rail End Treatments

Guardrail end treatments are crucial for safety, as they prevent vehicles from being impaled or redirected in the wrong direction if they hit the end of a guardrail. These treatments can be absorbent, like crash cushions, or redirective, guiding the vehicle safely away.

Truck-mounted attenuators (TMA)

Truck-mounted attenuators (TMAs) are devices mounted on work vehicles’ rear, designed to absorb and dissipate energy from impacting vehicles, minimizing damage to the errant vehicle and the work truck. Typically deployed in mobile or stationary work zones, they protect workers, equipment, and the driving public in high-risk rear-end collision areas. TMAs undergo rigorous testing to meet stringent safety standards, evaluated based on their ability to mitigate impact forces and reduce potential injuries to occupants.

Truck Trailer Mounted Attenuators (TTMAs)

Truck Trailer Mounted Attenuators (TTMAs) are akin to TMAs but are mounted on a trailer hitched to a work truck, providing a larger crumple zone beneficial in higher-speed scenarios. Utilized in both mobile and stationary work zones, TTMAs are often preferred for projects on high-speed roadways due to their enhanced impact absorption capacity. To ascertain their efficacy, TTMAs are subjected to stringent testing against safety standards, with their performance meticulously evaluated across various crash scenarios to ensure maximum safety.
