【摘要】 现代环岛以其延误少、节能环保以及安全性高等优点,被广泛地应用于国内外道路交叉节点处。通过研究无信号平面环岛进环交通事故,对其成因进行进一步划分,并使用朴素贝叶斯模型分析可能引发交通事故的原因,找出其中主要的因素,在此基础上进行贝叶斯决策,对有针对性地减少环岛出现的交通事故很有意义。更多还原

【Abstract】 Modern roundabout is widely used in intersections at home and abroad because of its decreasing delays,energy saving,environmental protection,higher safety and other advantages.It is very significant to reduce traffic accident at roundabouts professionally by studying on the entering-circulating traffic accident at unsigned plane roundabouts,further dividing it’ s reasons,using Naive Bayesian Classifier Model to analyze the possible factors that may lead to traffic accidents,finding out main factors,and doing Bayesian decision-making based on above analysis.更多还原
