基于主成分法的驾驶员违章事故分析

Analysis on Driver Peccancy Based on Principal Components Method

运用主成分法分析由驾驶员违规行为引发的道路交通事故损失。利用降维思想,用少数综合指标代替多个评价指标,以客观统计数据为依据,借助Spss统计软件运算得到综合评价值,使运算过程得以简化。

In this paper,the method of principal components analysis is applied to analyze all kinds of losses of road traffic accidents caused by the driver＇s various irregularities. With dimension reduction and a comprehensive index to replace multiple evaluation indexes,the comprehensive evaluation was obtained with the assistance of the Spss statistic software based on objective statistical data to avoid the cumbersome operation. The formation principle of the method and the results of the actual evaluation have universal application and popularizing value.
