2004年某县交通事故数据的挖掘分析

Mining analysis for traffic accident data in a county in 2004

为了对交通事故实施量化分析,通过图表、聚类、相关、偏相关及回归分析等统计方法对2004年某县交通事故的基本数据进行了分析。分析认为,导致该县交通事故直接经济损失的直接因素主要是受伤人数,而不是死亡人数和事故起数;同时从不同角度进行了事故原因分析,分析结果表明:加强周末交通监管力度,增加疏导交通的人数和时间等;加强好天气的交通管理;注重于驾驶人员和出行人员保持一个良好的心态及车辆自检问题;加大宣传和整治马路市场、事故黑点的力度等。

In order to conduct quantitative analysis for traffic accidents, the SPSS software is used for the examination of the basic situations of traffic accidents of a county in 2004. Through charts, clustering, correlation, partial correlation and regression, it is shown that the main factors that lead to the direct econmic losses are not the number of death and accidents, but the number of the injured. The authors in the paper analyze all the possible causes of the accidents from different angles and have offered the following suggestions to solve the problem. They are：the supervision for traffic should be strengthened at weekends; more staff should be sent for channeling traffic and they should work for longer time; there should be more work for traffic supervision during fine days; more educational work should be offered to both the drivers and passers-by; and publicity work, the clearing up of free markets near roads and improvement of black spots should be strengthened.
