The invention provides a regional traffic accident early warning method and system based on deep learning, and the method comprises the steps: obtaining traffic accident occurrence places in a historical period of time, carrying out the clustering of the traffic accident occurrence places based on a DBSCAN clustering algorithm, and obtaining a regional traffic accident point cluster; carrying out feature extraction on regional traffic accidents, constructing a mapping relation between traffic accident features and accident types, and training a deep learning model based on a deep learning algorithm; and detecting regional traffic characteristic data, predicting a vehicle accident risk through a deep learning model, and carrying out early warning on a corresponding vehicle. According to the scheme, the regional vehicle risk can be predicted, risk prompting can be accurately carried out on regional drivers, and traffic safety is guaranteed.
本发明提供一种基于深度学习的区域交通事故预警方法及系统,该方法包括:获取历史一段时间内交通事故发生地点,基于DBSCAN聚类算法对交通事故发生地点进行聚类,得到区域交通事故点簇;对区域交通事故进行特征提取,构建交通事故特征与事故类型的映射关系,并基于深度学习算法,对深度学习模型进行训练;检测区域交通特征数据,通过深度学习模型,预测车辆事故风险,并对对应的车辆进行预警。通过该方案可以预测区域车辆风险,准确对区域驾驶员进行风险提示,保障交通安全。
