摘　　要：通过对山区高速公路事故多发地现场调研和交通事故数据样本分析,总结山区高速公路道路特征和交通事故特点,研究山区高速公路不同道路环境下交通安全信息,指出山区高速公路应在弯道处实行大小车辆分别限速,并给出了限速方式:长大坡路段应提供整体性道路信息以及交通安全标志的设置要求;异常气候条件下须提供预警性信息。认为在山区高速公路建设中,可以通过对交通安全标志的合理化设计,在不改变公路线形情况下,能使山区高速公路弯道、长大坡等特殊路段的交通事故发生率明显降低。Based on site investigation in places where many traffic accidents take place on highway in mountainous area and analysis of data samples of traffic accidents,this paper concludes road characters of highways in mountainous area and features of traffic accidents,studies traffic safety information under different road environments on highways in mountainous area,points out respective speed limits for big and small vehicles should be executed at the curves of highways,and presents speed limit modes： in sections with long and big slopes integral road information should be provided and traffic safety markings be set up;under abnormal climatic conditions early warning information must be provided.According to the paper,in construction of expressways in mountainous area the reasonable design of traffic safety marks without changing highway alignment enables obvious decrease of traffic accident rate in special sections such as curves,long and big slopes on expressways in mountainous areas.
