摘　　要：以提高高速公路互通立交桥安全性为目的,通过调查辽宁省多条高速公路的实际运营状况和道路交通事故的形态,在定性分析立交区域交通事故产生原因的基础上,结合事故数法-事故率法等评判法则,对互通立交桥区域发生交通事故的特征点及成因深入分析,从竞技法的原理探索立交桥各单元事故黑点的判别标准,从而构建了互通立交桥各单元的事故评判模型,并结合实际事例进行了验证,为互通立交桥事故黑点的甄别提出了一种新的方法,对提升互通立交桥的安全性具有重大的现实意义。In order to improve the security of freeway interchanges in Liaoning province the paper in-depth analyze features and causes of traffic accidents in the area of interchange by investigating the actual operation conditions and road traffic patterns of a number of freeway,which is based on the qualitative analysis of the causes of traffic accidents in interchange area and combined with the judge rules on the Number of Accidents-Accident Rate.In addition,the paper builds the accident evaluation model of each unit of interchange which is validated with actual cases through the exploration of the accident black spots criterion in each unit of interchange based on competitive method and proposes a new method to discriminate the accident black spots of interchange,which is of great practical significance to enhance the security of interchange.
