摘　　要：针对山区干线公路交叉口繁多的问题,以干线公路接入支路的T形交叉口为重点分析对象。首先,对山区干线公路交叉口的基本特征以及交叉口的主要风险因素,如交通参与者、车辆以及道路交通环境等对交叉口展开分析。其次,从交通参与者以及道路与环境因素对山区干线公路交叉口存在的主要问题进行分析。最后,结合山区干线公路的具体运营特征,基于提出的改善设计原则,从标志标线系统、视线诱导以及安全防护的角度提出了安全有效、经济合理的山区干线公路交叉口改善措施,其可以有效提升交叉口的安全行车水平。Regarding the problems of numerous arterial road intersections in the mountainous areas,the T-shaped intersections of the trunk roads connecting the feeder roads are taken as the analysis objects.First of all,the basic characteristics of main road intersections in mountainous areas and the main risk factors of intersections,such as traffic participants,vehicles,and road traffic environment are analyzed.Secondly,the main problems existing in the intersections of arterial highways in mountainous areas are analyzed from the perspectives of traffic participants and roads and environmental factors.Finally,based on the specific operational characteristics of mountainous highways,according to the proposed improvement design principles and from the perspective of the marking and marking system,sight guidance,and safety protection,the safe and effective,economical and reasonable mountainous highway improvement measures are proposed,which can effectively improve safe driving at intersections.
