This article introduced the first national milestone in the development of highway construction and the subsequent safety problems at home and abroad for highway safety devices designed to analyze the status quo and against Jiang Feng to the actual Yanji highway projects, detailed application to run Highway speed theory of the need for safety measures designed.In this paper, based on highway construction design, engineering combined with the existing topography using a low-index vertical line of actual cases, the use of the theoretical speed of the entire project, and based on an analysis of the results targeted for safety measures Design, to achieve people-oriented, the purpose of safety first, the highway signs marking, guard rails, the standard profile, as well as the special Anti plate section of the hedge, such as lane use, as far as possible to achieve small radius, grew up on steep slopes Bending slope, and other disadvantaged sections of combination use of safety devices designed for drivers and passengers are reminded to warn and protect. And summed up a set of effective use of the speed theory to guide design of the highway safety measures.Finally, according to highway speed calculations, the safety design approach and recommended a specific design.
