摘　　要：为分析城市道路交通事故的时空分布模式,本文基于网络空间线性最邻近指数和Knox时空检验方法,对武汉市青山区道路交通事故的热点路段分布以及时空交互模式进行检验。实验结果表明,城市道路交通事故在空间和时空层面均呈现显著聚集分布。事故热点主要分布在主干道和道路交叉口等人流量大和路网密集的区域,显著性时空交互现象发生于近时空区域内。本文结果可为交通事故防控、交通设施优化提供理论参考。In order to analyze the spatio-temporaldistribution patterns of the urban road traffic accidents,this paper chooses minor traffic accidents data in Qingshan District of Wuhan as the research object,utilizes nearest neighbor index based on network space to explore distribution of accident hotspots,and the Knox test method to examine thespatio-temporal interaction patterns. The results show that,the urban road traffic accidents have presented significantly aggregated distributions in spatial and temporal,accident hotspots are mainly distributed in densely populated areas and roads especially in the arterial roads and intersections,thespatio-temporal interactive phenomenon occurred in neighboring time and space area. The results can provide theory for the traffic accident prevention and the optimization of traffic facilities.
