Which term is a barrier commonly located outside the deck face?

Explanation:
Barriers along the edge of a bridge deck are there to keep traffic and pedestrians from leaving the deck and to define the exterior boundary. The parapet is the barrier that sits on the outside face of the deck—essentially a wall along the edge that often rises above the deck surface and can carry a railing if needed. This exterior boundary function is what sets parapet apart from other terms. A railing is a type of barrier that may be mounted on or atop the parapet and is more about the handhold and fall-prevention height, while the other terms refer to geometry or loading concepts rather than edge barriers.
