Abstract: The study used factor analysis and cluster analysis methods to deeply discuss the causes and impact mechanisms of urban traffic accidents. Through careful cleaning and information mining of traffic accident data, YcpNoyoAibZyrAdH3pzkC1Kk8oudKeqg5J0vA24jBnc=the accident time characteristics and driver characteristics are analyzed. The research results reveal the high incidence of accidents during morning and evening peak hours, and point out the main factors affecting accidents. In addition, it was also found that accidents were high in moderate rain, and vehicles from other cities accounted for a certain proportion of accidzOhNx3Kngy5fzQRRlnBv4dTaMPrIUvrrEyXUtb64Dg0=ents. The study proposes targeted preventive measures, such as developing public transportation, off-peak commuting policies, strengthening driver's license review and improving driver safety awareness, aiming to provide scientific basis for traffic management departments to reduce accident rates.

城市化與機動化進程的快速推進,使得交通事故成為全球性的城市公共安全問題。交通事故不僅威脅著人們的生命財產(chǎn)安全,還對城市的可持續(xù)發(fā)展構(gòu)成阻礙。系統(tǒng)地分析交通事故的成因,對于制定有效的交通管理策略、降低事故發(fā)生率具有重要的理論和實踐意義。
傳統(tǒng)的交通事故成因分析方法主要包括統(tǒng)計分析、專家調(diào)查、事故調(diào)查等。鄭來等[1]通過融合T-S模糊故障樹和貝葉斯網(wǎng)絡對重特大交通事故進行深入分析,確定了操作不當、超速等為主要致因。此外,王俊美等[2]利用數(shù)理統(tǒng)計和交叉分析方法,對事故類型、事故天氣等因素與交通事故的關(guān)系進行了研究。
隨著大數(shù)據(jù)和計算機技術(shù)的發(fā)展,數(shù)據(jù)挖掘技術(shù)在交通事故成因分析中的應用日益廣泛。……
