F-shape barrier

It is a modification of the widely used Jersey barrier design, and is generally considered safer.

[1] A parametric study, one that systematically varies the parameters, was done through computer simulations of barrier profiles labeled A through F. The result showed that the one labeled F performed better than even the shape of the Jersey barrier.

A series of full-scale crash tests later confirmed these computer-based results.

The Jersey-shape barrier was already in wide use, and it also met the crash-test criteria.

This lower slope break point reduces vehicle lift, improving the barrier's performance.
