摘　　要：分心驾驶是影响交通事故发生的重要因素,当前对分心驾驶的研究集中于驾驶员驾驶行为的识别,缺少对事故发生机理的研究。为了提高高速公路行车安全,以某地区高速公路交通事故为基础,考虑驾驶员、车辆、道路、环境等因素间的耦合关系,运用关联规则算法,分析事故发生的季节性差异,多角度挖掘高速公路分心驾驶事故的潜在规律。结果表明:因驾驶员未集中注意力而引发的事故具有一定的时空规律,工作日通勤高峰时段发生事故更多,空间上存在事故多发点;无论夏季或冬季,平直路段与良好天气组合环境下发生分心驾驶事故的事故风险更高;事故严重程度多为仅财产损失事故或伤人事故,发生死亡事故比例较低;夏季和冬季引发的分心事故在事故致因及事故发生形态上存在差异。研究成果可为交通管理者制定创新政策,提升道路安全水平提供理论指导。Distracted driving is a significant factor influencing traffic accidents.Current research primarily focuses on identifying distracted behaviors among drivers,while the investigation into accident mechanisms remains limited.To improve highway driving safety,the coupling relationships among drivers,vehicles,roads,and environments were explored,based on traffic accident data in a specific region.Utilizing association rule algorithms,seasonal variations in accident occurrences were analyzed,and potential patterns of distracted driving accidents were explored from multiple perspectives.The results show that accidents caused by driver distraction exhibit certain temporal and spatial patterns,with a higher frequency during weekday commuting peak hours and identifiable accident-prone locations.Regardless of season,distracted driving accidents tend to occur more frequently on straight road segments under favorable weather conditions.The severity of accidents predominantly involves property damage or injuries,with a low proportion of fatalities.Differences in accident causation and occurrence patterns are observed between summer and winter distracted driving accidents.These findings provide valuable insights for traffic managers to develop innovative policies and enhance road safety.
