Non-Gating Guardrail Terminal

Gating allows guardrails to form a plastic hinge, and a portion of that guardrail will swing open, like a gate, and allow the vehicle to pass behind. Before now, gating was a feature of all guardrail terminals.

The TRB Highway Innovations Deserving Exploratory Analysis (IDEA) Program's Non-Gating Guardrail Terminal is the final report for the National Cooperative Highway Research Program's IDEA Project 212, which has proven that a non-gating guardrail terminal is possible. A prototype was developed as part of the project that has been successfully crash tested using common vehicle types.
