NCHRP Report 230, published in March 1981, contains recommended procedures for evaluating the safety performance of highway features. These recommendations were based on a synthesis of information found in the literature and a state-of-the-art survey, and on advice obtained from a selected group of acknowledged experts. Since 1981, the mix and characteristics of highway vehicles have changed substantially; safety features not considered in Report 230 have come into use, and research efforts using full-scale crash tests, bogie and pendulum tests, computer simulations, and traffic accident analyses have resulted in improved understanding of vehicle interactions with highway features, including roadside terrain. The object of this update is to promulgate recommended procedures for the safety performance evaluation of both temporary and permanent highway features in such a manner as to reflect advances in technology and to accommodate current and anticipated roadway and vehicle characteristics. This presentation discusses the status of the update, including the major changes being proposed.
