Abstract: Various embodiments for a coiled containment guardrail system and terminal are described. A guardrail system can include a terminal head configured for placement at a distal end of a guardrail beam, where the terminal head includes a canister having a hollow interior and an impact surface. A chute can be coupled to the terminal head, where the chute is configured to guide a guardrail beam into the terminal head in response to an impact being experienced at the impact surface. The terminal head may further include a flattening device coupled to the chute configured to flatten the guardrail beam in response to the impact being experienced at the terminal head. The canister can be configured to coil and store the guardrail beam as flattened by the flattening device in the hollow interior of the canister.

Abstract: A self-restoring crash cushion including multiple diaphragms spaced along a length direction of the cushion, an elongated track adapted to be anchored to the ground that extends along the length direction under the cushion, the diaphragms being mounted to the track in a manner in which they can slide along the track when impacted by a moving vehicle or when the cushion is being restored, and means for dissipating energy of the moving vehicle.
