摘　　要：在借鉴国内外城市交通安全评价指标及方法的基础上,结合我国实际情况,构建了城市交通安全水平评价指标体系,并参考城市道路交通管理评价指标体系,确定安全评价指标分级及标准。在此基础上,采用改进灰色聚类法对城市交通安全水平进行综合评价,根据聚类白化数确定三类灰类白化函数计算灰类白化值。以江苏省相关城市为实例,对城市交通安全水平进行了综合评价。The urban traffic safety assessments home and abroad are analyzed in order to establish the assessment system of urban traffic safety of China. Then, the classification and standards of safety assessment are made by referring to Urban Traffic Safety Assessment System. Moreover, the urban traffic safety levels are assessed by using improved gray clustering method. The gray values are determined in traditional gray clustering method by using accumulation frequency. Taking the cities in Jiangsu Province as examples, the urban traffic safety levels are assessed.
