摘　　要：交通冲突技术是交通领域新兴的一种非事故统计技术,文章采用该技术,以典型时段冲突数与当量交通量的比值作为评价标准,对城市交叉口的安全状况进行定量评价,结合混合模糊聚类算法进行聚类分析,得到镇江市镇大公路上8个交叉口安全评价结果;结果符合实际情况,表明该方法可行。The traffic conflict technique is a new evaluating method based on non-accident stansncs m the traffic safety field. This paper applies this technique to the consideration of the whole traffic condition at urban intersections, and the ratio between the number of traffic conflicts and the traffic volume in typical periods is chosen as the index. The mixed fuzzy clustering method is used to evaluate the safety condition of 8 intersections on the Zhenda road in Zhenjiang City. The conclusion accords with the fact, which proves that the presented method is feasible.
