摘要
近年来我国交通基础设施的建设发展迅速,然而道路交通事故也在不断上升。根据2000年和2001年全国100多万起交通事故资料,采用χ2检验和系统聚类法对事故次数、死亡人数、受伤人数和直接经济损失的时间分布进行详细地分析,结果表明,事故的分布与时间有密切的关系。
The construction of transportation infrastructure develops rapidly in China;however,the number of traffic accidents is rising continuously.The distribution of accidents has a close relationship with time.On the basis of more than one million road traffic accident records in China from 2000 to 2001,this paper adopts χ~2 test and hierarchical clustering method to explore time distribution of the accidents,the direct economic loss,the number of the death and the injured.
