the improvement of speed of vehicle and growth of traffic volume,road traffic accidents is on the rise every on data mining and analysis of traffic accidents big data,Kmeans cluster analysis and Apriori association rules analysis traffic accident tendency and out frequent accident sections and the cause of accident and peak hours,base on data analysis result,improve the traffic situation,reduce tarffic accident,improve the efficiency of traffic system.Key words:transportation system、kmeans cluster、Apriori algorithm一、引言1 隨著我國(guó)經(jīng)濟(jì)的發(fā)展,交通安全問(wèn)題日益突出,已經(jīng)引起了人們的廣泛關(guān)注。 國(guó)外交通事故大數(shù)據(jù)挖掘分析摘要:近年來(lái),隨著車(chē)速的提高及交通量的增長(zhǎng),道路交通事故每年呈上升趨勢(shì)。通過(guò)對(duì)交通事故大數(shù)據(jù)挖掘分析,kmeans聚類(lèi)分析和Apriori關(guān)聯(lián)規(guī)則分析交通事故的趨勢(shì)和模式,找出事故頻發(fā)的路段和引發(fā)事故的原因以及事故頻發(fā)的高峰期,以數(shù)據(jù)分析結(jié)果為依據(jù),改善交通狀況,減少交通事故,提高交通系統(tǒng)的效率。如何對(duì)大量的交通事故信息進(jìn)行數(shù)據(jù)挖掘,尋找出其中隱藏的知識(shí)與規(guī)律,用以改善交通
