用改进的灰色关联度分析交通事故成因

Traffic Accidents Reasons Analyzed with Innovated Gray Association Degree

改进的灰色关联模型与普通灰色关联模型相比,可以突出关联度的微小变化,且更加科学。通过实例,用改进的灰关联对道路交通事故成因进行了分析,并与普通灰色关联分析进行了比较,发现前者分析结果更具层次性、差异性,更容易识别事故主要、次要和潜在的成因。

Compared with common gray association model, the innovated gray association model may better display minor change in association degree and it is more scientific. With practical instances, the innovated gray association is used to analyze the causes of road traffic accidents, and the result is compared with the common gray association analysis, it is found that the analysis result of the former has better hierarchical structure and better variety. With the former model, it＇ s easier to identify major, minor and potential causes of accidents.
