abstract="The need for national, uniform designs and applications of roadside delineation has long been recognized by traffic authorities. A comprehensive study was, therefore, undertaken to obtain a better understanding of present practices of roadside delineation and to further establish criteria for the selection of an optimum roadside delineation treatment at a given condition. In this study, an extensive literature review and a national survey of all state highway departments were conducted to form a state-of-the-art summary of roadside delineation concepts. Attempts to formulate a uniform selection process for roadside delineation treatments involved discussions of evaluation criteria and presentation of a suggested selection program. The results of this study provide updated and thorough knowledge of existing and proposed roadside delineation techniques.<p /><p>Language: en</p>",
