摘　　要：通过简介国外道路安全评价工作,阐述开展道路安全评价的必要性。公路线形条件与公路交通安全有着密切的联系,顺畅的线形是行驶安全的基本保障。从提高道路安全角度出发,对公路线形设计中潜在的不利安全因素进行鉴别以便消除或减弱道路危险因素,就显得尤为重要。通过对运行速度的计算,并分析了公路运行速度与道路组成部分的联系,提出相应的安全评价指标和建议。最后结合实际工程,找出了设计中潜在的安全隐患并为以后设计提供相应的建议。With a review of the advance of highway safety audit researches in the abroad, it proves that highway safety audit is of great importance. The condition of road alignment is closely related with road safety, comfortable road alignment is the basic guarantee to the vehicle safety. In the aspect of elevating the road safety, it is important to find and reduce or removing these potential danger factors. Some indexes and suggests for road safety audit are proposed according to the calculation of operating speed and the analysis of the relationship between the operating speed and road components. In combination with a real project, the potential danger factors were found and the advices for future design were proposed as well.
