摘要
考虑到各种交通事故因素对交通事故属性本身的影响有轻重之分,基于传统的关联规则挖掘模型,提出了一种加权关联规则的模型,设计与实现了加权关联规则的挖掘算法,并应用到道路交通事故属性的分析中。
Different factors of traffic accidents may have different impacts on the occurrence of accidents. A weighted association rule model based on the traditional association rule model was proposed. Then, a mining algorithm of the proposed model was developed and applied in analyzing the property of road traffic accidents.
