| 摘 要： | 利用粗集理论,以事故死亡人数为指标,分别以月、周、日和小时为时间粒度,以吉林省某高速公路1999年至2004年发生的交通事故统计数据为例,对道路交通事故死亡人数的时间分布规律进行分析。结果表明,道路交通事故死亡人数的分布与时间有密切的关系,并且不同时间粒度对死亡人数分布影响的重要程度又存在显著差别。

| Abstract: | This paper takes the traffic accidents which happened in expressways of Jilin province from 1999 to 2004 for example,using rough set analyse takes death toll from accidents as index,takes month,week,day and hour as time granularity,study the datum deeply and reach the affect rule of time distribution of death toll from traffic accident.The results indicate that there is consanguineous connection between the distribution of death toll from traffic accidents and time,and there is remarkably difference between the important degrees of influencing on distribution of death toll by different time granularity. |
