摘要
交通事故成因复杂且具有不确定性,难以用一两种因素表征。为提取影响交通事故的核心因素并量化各因素的影响力,引入不确定性分析方法——粗糙集理论。首先根据历史事故数据建立粗糙集信息决策表,之后利用粗糙集理论的简约算法求出各因素相对于事故形态的属性重要度,最终判断出各因素对事故形态的影响程度,为道路事故形态预测模型的建立提供科学、合理的指标选取依据。
The causes of traffic accidents are complex and uncertain, and it is difficult to be represented by one or two factors. To obtain the core factors affecting the traffic accident and quantify the factors, the article introduces rough set theory. Firstly, according to the historical accident data, the information deci-sion table of rough set is established. Then, the simple algorithm of rough set model is used to calculate the important degree of each factor. Finally, the influence degree of each factor on traffic accidents is got, so it can provide basis for scientific decision.
