| 摘 要： | 针对道路交通安全概念的模糊性和随机性,运用聚类分析方法对道路安全水平等级进行了划分。以云理论为基础,利用云发生器算法构建了道路安全评价的云模型。选取高速公路作为评价对象,分析其整体安全水平。实例表明,基于云理论的评价方法所得结果更加符合客观实际,而且具有广泛的适用性。

| Abstract: | In view of the randomness and fuzziness of road safety,different safety levels were classified by using clustering method.Based on the cloud theory,a cloud model for road safety evaluation was developed based on the cloud generator algorithm.A set of freeways were selected and their safety levels were analyzed.The evaluation results show that the cloud model can describe the actual road safety level more objectively.Therefore,it should have a broad applicability. |
