The invention discloses a model and a method for evaluating and analyzing traffic situation influence of road section emergencies, and the method comprises the steps: deducing related follow-up traffic road condition evolution situation based on a Bayesian network and other related mining algorithms; the method comprises the following steps: collecting vehicle and road condition information, traffic accident grade and other data in a period of time before and after a violation moment of a violation vehicle from a traffic vehicle management system database, sorting and classifying the collected information, establishing a training set training model of a Bayesian network evaluation model, and incorporating a prediction grade into a model training range; according to the method, the traffic violation misjudgment is identified, the traffic section situation is evaluated, the decision support capability is provided for improving the emergency disposal of expressway emergencies, and meanwhile, based on a Bayesian network and other related mining algorithms, the related follow-up traffic road condition evolution situation can be deduced, and decision support is carried out on the emergencies.

    本发明公开了一种路段突发事件交通态势影响评估分析模型及方法,基于贝叶斯网络等相关挖掘算法,推估相关后续交通路况演进态势通过建立贝叶斯网络评估模型,从交通车辆管理系统数据库中收集违章车辆违章时刻的前后一段时间内的车辆及路况信息及交通事故等级等数据,对所收集的信息进行整理分类,建立起贝叶斯网络评估模型的训练集训练模型,并将预测等级纳入模型训练范围,对违章误判进行识别,对交通路段态势进行评估,为提升高速公路突发事件应急处置提供决策支持能力,同时基于贝叶斯网络等相关挖掘算法,可推估相关后续交通路况演进态势,对突发应急事件进行决策支持。
