Full-scale tests were conducted to evaluate and compare the performance of three median barriers of different configuration and lateral stiffness: (a) the Metal Beam Guard Fence (MBGF) consisting of steel W-beam guardrails on weak breakaway steel posts, (b) the E-3 consisting of strong elliptical steel rail members mounted on steel posts and (3) the concrete median barrier (CMB) with sloping faces. Information is presented on the safety, economic, and aesthetic considerations for each of the three barriers investigated.
