ABSTRACT:
A narrow stationary impact attenuation system (10) for reducing the severity of vehicular collisions occasioned by an errant vehicle striking an immovable object at narrow hazard sites. The subject narrow stationary impact attenuation system (10) includes crash cushion means (12), lateral stability means (14), backup means (16), support means (18), lateral deflection means (20), vehicle anti-vaulting means (22), redirection means (24), and base means (26). The lateral stability means (14) extends the length of the crash cushion means (12) on either side thereof. The backup means (16) is positioned in juxtaposed relation to the crash cushion means (12) at the rear thereof. The support means (18) is positioned in juxtaposed relation to the crash cushion means (12) at the front thereof. The lateral deflection means (20), the vehicle anti-vaulting means (22) and the redirection means (24) are each mounted in supported relation at selected positions relative to the crash cushion means (12). The base means (26) provides the pavement support for all of the components that collectively comprise the subject narrow stationary impact attenuation system.
