摘　　要：行车安全是高速公路设计的重要因素,道路设计合理性直接决定行车的舒适性和安全性。探讨了道路相关设计因素对高速公路行车安全的影响,对道路平曲线、竖曲线和坡度等线形因素,道路横断面车道布置以及道路辅助安保设施等进行了分析,研究了行车安全与这些因素的内在关系,并对道路的设计提出了要求,以形成高质量的高速公路设计方法,保障车辆的行车安全,并尽可能降低交通事故的发生。The traffic safety is the important factor of expressway design. The road design rationality directly decides the traffic comfort and security. The article discusses the influence of relative road design factors on the expressway traffic safety, analyzes the linear factors of road horizontal curve, vertical curve and gradient, the layout of road cross-section lane and the auxiliary security facilities of road, studies the internal relation between the traffic safety and these factors, and puts forward the requirements of road design so as to form the high quality of expressway design method, to ensure the vertical traffic safety and to reduce the traffic accidents as far as possible.
