The ETI Roller Barrier System Takes On Massive Vehicle Collisions Making The Roads Safer
Показать описание
This is the innovative ETI Roller Barrier System, in which guardrails are equipped with rollers that cushion the impact of collisions. Developed by the South Korean Firm, ETI, Or evolution in traffic innovation, these guardrails convert collision energy into rotational energy to prevent cars and other vehicles from diverting off the road and causing a secondary crash.
This pioneering system reduces the overall forces experienced by the occupants of the crashing vehicle. This concept brings us back to the basics of physics where "a vehicle crashing into an immovable barrier is subject to the same force as if it was hitting an equal size vehicle travelling the same speed in the opposite direction. In other words, these forces are immense, and converting them into a glancing blow would greatly reduce the risk of injury to passengers. It has also been pointed out that the design of the ETI Roller Barrier System allows the out of control vehicle to bounce back into its lane with considerably less momentum, and therefore energy, than it had when it hit the railing. The guardrails have super bright reflectors that improve drivers' visibility. The shock absorbing rollers, or rolling drums, are made up of ethyl vinyl acetate material, which has superb flexibility and elasticity compared to other polyethylene based resins. It is comparable to rubber, but lighter. The material is also durable, long lasting, and chemically resistant, and it doesn't degrade over time due to UV exposure. The design of the tightly spaced struts form heavy duty support to prevent the crashed vehicle from overturning the guardrail into a possibly hazardous area.
