【摘要】 基于国内某城市主要路网某年全年所发生的交通事故统计数据,以Moran模型为基础,研究道路交通事故的空间位置及相互关系,探讨道路交通事故的空间自相关特性,分析道路交通事故的空间聚集性。空间自相关分析方法强调了"位置"因素的重要性,研究表明,该方法是一种有效可行的分析事故产生原因的新方法,其应用为进一步提出具体预防措施以及验证预防措施的有效性提供了一种新的思路和手段。更多还原

【Abstract】 Based on the statistic data of traffic accidents in a major domestic road network in a city,a Moran model was applied to studying the mutual relation between spatial locations of road traffic accidents.Spatial autocorrelation and aggregation of road traffic accidents were analyzed.Spatial autocorrelation analysis methods emphasized the importance of "location" factor.The studies have shown that this is an effective and feasible new method to analyze the causes for the accidents,which provides a new idea and way for further putting forward prevention measures and verifying their effectiveness.更多还原
