Korean guardrail safety barrier system on a roll to safety
A Korean company that specialises in guardrail systems and traffic cones has developed a new barrier system that incorporates rollers to absorb impact and steer vehicle back into the traffic.
Concrete barriers and conventional metal guardrail system are effective, but cause major damage to the impacting vehicle and the guardrail itself. ETI ltd (Evolution in Traffic Innovation) believe their softer guardrail system will protect drivers from the impact shock and save lives.
The rolling barrier system is designed to do more than absorb impact energy, it converts that energy into rotational energy which propels the vehicle back into its lane instead of through or into an immovable barrier.
The rollers are made from tough ethylene-vinyl acetate (EVA) which has excellent shock absorption power. EVA has superior flexibility and elasticity than other polyethylene vinyl materials.
The three-dimensional rotating barrels are covered in high intensity reflective sheeting which increase delineation and make the barrier highly visibility to help prevent accidents.
The rollers prevent second collision accidents and lane departure, guiding a vehicle in the traffic flow direction to prevent rear-end collisions with following cars.
Maintenance is simple as sections and individual rollers can be easily and quickly replaced.
