基于数据挖掘的道路运行安全因素关联分析

Association analysis of the road running safety factors based on data mining technology

利用方差分析方法,从大量公路安全数据中,对影响安全的时间因素进行量化关联分析,获得季节、星期、时段对高速公路安全影响的重要结论,可为今后的风险分析和预警模型提供科学依据.

A quantitative relation analysis was done on the effect of time factor for road running safety from large quantities of highway safety data with variance analysis method,and important conclusions respectively from seasons,weeks and hours about highway safety were obtained,which can provide the scientific basis for risk analysis and early warning model in the future.
