摘要
以某城市城乡结合部2014—2017年交通事故数据为基础,基于关联规则与灰色关联分析城乡结合部交通事故致因的关联性.利用Apriori算法探究城乡结合部交通事故致因因素之间的关联规则,基于灰色关联分析法测算事故致因对城乡结合部事故频次、事故严重程度的关联度.结果表明:出行时间、驾驶员操作不当、驾驶员违反交规是城乡结合部交通事故的主要致因因素;出行时间、平直道、驾驶员操作不当对城乡结合部交通事故严重程度有显著影响;驾驶员无证驾驶所造成的事故次数虽然较低,但其严重程度较高;平直道发生交通事故的频次高,且相对较为严重.
Based on the traffic accident data from 2014 to 2017 in the urban-rural fringe of a city,the correlation of traffic accident causes in the urban-rural fringe based on association rules and grey correlation were analyzed.The Apriori algorithm was used to explore the association rules between traffic accident causes in urban-rural fringe,and the correlation degree of accident causes to accident frequency and accident severity in urban-rural fringe was calculated based on grey correlation analysis.The results show that travel time,improper operation of drivers and violation of traffic regulations are the main causes of traffic accidents in the urban-rural fringe.Travel time,straight road and improper driver operation have significant influence on the severity of traffic accidents in urban-rural fringe.Although the number of accidents caused by drivers in driving without a license is low,its severity is high.The frequency of traffic accidents on straight roads is high and relatively serious.
