Abstract: On the basis of analyzing the highway safety of current China, the correlation rules were used to deeply analyze the main characteristics of 90 traffic accidents mortality on a multilane highway. Several rules were elaborated, such as: the first and the fourth lane were accident prone; accidents mortality of heavy semitrailer trains and minibuses was high; the driver and passengers without wearing a seatbelt and flying out of the vehicle died more; the death toll from fatigue driving was the most. The results show that: in highway management, to reduce the occurrence of casualty accidents, the control of heavyduty semitrailer trains and minibuses should be focused; the behavior of the driver or passengers without wearing seat belts and the illegal activities of fatigue driving should be severely investigated; and the traffic behavior of the personnel off the vehicle should be regulated.

摘要： 在分析中国高速公路安全现状的基础上，应用关联规则深入剖析某条多车道高速公路90起交通死亡事故主要特征，阐述多车道高速公路具有第一、第四车道事故高发、涉及重型半挂汽车列车和小型客车事故死亡率高、驾乘人员未系安全带飞出车外死亡人数较多、疲劳驾驶导致的死亡人数最多等规律。研究表明：高速公路应重点管控重型半挂汽车列车和小型客车，严查驾乘人员未系安全带和疲劳驾驶违法行为，规范下车人员的交通行为，进而降低伤亡事故的发生几率。
