Smart Cushion

Highway Safety Products

The Smart Cushion crash attenuator is a revolutionary, speed-dependent product that varies stopping resistance during an impact. The Smart Cushion crash attenuator allows lighter and slower-moving vehicles to have longer ridedown distances and lower ridedown G forces.

Unlike fixed-resistance attenuators, the Smart Cushion attenuator does not reach maximum stopping resistance unless a vehicle is traveling at the maximum design speed. This fully redirective, non-gating, bi-directional, impact attenuator was designed for maximum safety and reusability, as well as outstanding durability before, during and after an impact.

The Smart Cushion is the only attenuator with a reverse-tapered design to eliminate side panel stress during a collapse. It also has an extremely low angle of exit on side impacts (<1°) to keep vehicles from rebounding back into traffic and causing secondary accidents. This is the lowest angle of exit for any redirective attenuator on the market.

Safety Benefits

  • Variable force (speed-dependent), not fixed force, provides consistent deceleration during ridedown.
  • Longer ridedown distances and lower sustained G forces for lighter or slower-moving vehicles.
  • Low angle of exit on side impacts (
  • Quick and easy resetting for reduced worker exposure to traffic.
  • Reduced out-of-service time to maximize highway safety.

Cost Benefits

  • Minimal replacement parts requirement reduces spare parts inventory and parts costs.
  • Quick, easy resetting reduces labor and traffic control costs.
  • The new, reverse-tapered design eliminates side panel stress on frontal impacts to reduce damage and system fatigue from multiple impacts.
  • Low life cycle cost benefits increase dramatically as impacts occur
