摘　　要：为准确评价无信号控制交叉口的交通安全状况,先依据交通冲突技术的相关研究结论,结合文献分析,选择同交叉口冲突高度相关的交叉口交通流相关数据作为评价无信号控制交叉口交通安全的指标。再根据实地调研,以河北省某地无信号控制交叉口的交通流相关数据为基础,结合熵权法与层次分析法综合得到所选指标的权重。在此基础上利用所选指标与所得指标权重构建无信号控制交叉口的安全评价模型,对无信号控制交叉口的交通安全状况进行评价。In order to accurately evaluate the traffic safety of non signalized intersections,firstly,according to the relevant research conclusions of traffic conflict technology and literature analysis,the intersection traffic flow data highly related to intersection conflict is selected as the index to evaluate the traffic safety of non signalized intersections.Then according to the field investigation,based on the traffic flow related data of a non signalized intersection in Hebei province,the weight of the selected index is obtained by combining Entropy weight method and Analytic Hierarchy Process.On this basis,the safety evaluation model of unsignalized intersection is constructed by using the selected index and the obtained index weight to evaluate the traffic safety of unsignalized intersection.
