Disclosed is an end treatment array for crash attenuation of vehicle impacts on traffic protection barriers. The array includes a transition barrier module comprising first and second side walls, first and second end walls, a top wall, and a bottom wall. The module walls together define a substantially enclosed interior space, the transition barrier module having a predetermined width and length; and a containment impact sled comprising an axially extending frame. The frame has a width sufficient to contain the transition barrier module within said frame when in an assembled configuration, and having an axial length which is at least one half the length of said transition barrier module, the frame having an open end and an end cap or upright wall closing the other end thereof and defining an interior volume adapted to capture debris during a vehicular impact. The end cap or upright wall of the containment impact sled is attached to one end of the transition barrier module in said assembled configuration, so that the transition barrier module is disposed in said interior volume. The transition barrier module is fabricated of plastic and the interior space is hollow and unfilled with any ballasting material. The containment impact sled further comprises a floor. |
