摘要

In Japan, the two-lane expressways without median strips have been widely introduced toextend the length of expressways in service with less construction costs. However, theexpressways have several problems such as no-overtaking chance, low posted speed,and high risk of fatal head-on collisions. The wire-rope guardrail systems, which can beseen as an alternative to median strips, involve the use of thin posts, have a bufferingfunction and require minimal with to installation. In this study, combinations of differentpost heights/hardness levels, shapes, numbers/heights of wire ropes, tension levels, postintervals and other values were examined to find the optimal specifications in order tosolve the challenge of reducing the extrusion of vehicles into the opposite lane based onwire rope deflection to absorb impact. The results of the performance test conducted inJanuary 2012 confirmed that the wire rope guardrail system developed satisfied the guardfence installation Am performance standard criteria for highway median strips. The systemwas introduced on a trial basis on sections of the Ban-etsu Expressway, the HokkaidoExpressway and Route 275 in 2012 and the Kisei Expressway in 2013.
