Abstract

The Midwest Guardrail System (MGS) has been shown to provide exceptional redirective capability in standard and special applications. However, the roadway width required to install a guardrail system with a blockout is not always available. In response, a nonproprietary nonblocked MGS was developed and successfully crash tested according to the testing standards established in the Manual for Assessing Safety Hardware. This study compared results from 1100C small car and 2270P pickup truck tests for the standard (blockout) and nonblocked versions of the MGS and concluded that the standard MGS performed better than the nonblocked MGS. As a result, it is recommended that the nonblocked MGS be used only in places where roadway width is a limiting parameter. If width is not restricted, use of a blockout as designated in the design drawings of the standard MGS is still recommended.
