摘　　要：交叉口是道路交通事故的多发地带,而交叉口及交叉周围道路的几何条件又是影响道路行车安全的关键因素;针对道路的竖曲线、纵坡、视距等关键因素进行了实地调研,并利用调研得到数据和相关规范,运用数学方法对其如何影响行车安全进行了分析。An intersection is a place with frequent road traffic accidents,and the key factor affecting road traffic safety is geometry condition of the intersection and its surroundings. According to the key factors such as vertical curve,longitudinal slope and stadia and so on,the spot survey is conducted,by using the obtained data and the related specification from the survey,how it affects the traffic safety is analyzed by mathematical methods.

关 键 词：交叉口 竖曲线 高长纵坡 视距 安全
