A security barrier system for use with a trafficable surface and a site requiring protection from advancing vehicles includes a visual indicator element having an appearance that is distinctive from the trafficable surface and disposed adjacent to the trafficable surface. A composite bed system includes a first structure beneath a second structure, where the first structure includes a deformable material that collapses under vehicle loads, and the second structure includes a pedestrian cover surface of a different material over the deformable material that conceals the deformable material and supports pedestrian traffic over the deformable material without permanently collapsing the deformable material. A pedestrian sidewalk is located between the bed and the visual indicator element, and a containment structure contains the bed system and resists the impact of a vehicle that has traversed the bed system.
