The invention relates to the technical field of traffic safety management, in particular to a vehicle abnormal driving recognition and early warning method and system. The method comprises the following steps: firstly, acquiring vehicle position, speed, direction and driver operation data in real time, then correcting time sequence data by adopting a smooth denoising method of adaptive segmented clustering, generating an information confirmation code through standardization, and then carrying out weighted fusion on multi-source data to obtain a multi-source data fusion model; the strategy decision-making module is used for extracting vehicle speed change rate, lane deviation degree and driver behavior characteristic key indexes, identifying and grading abnormal driving behaviors by setting a threshold value, calculating a comprehensive abnormal score, and generating a grading intervention strategy for slight, medium and serious anomalies according to a comparison result of the abnormal score and the set threshold value. And finally, combining automatic intervention in the vehicle with global coordinated intervention of a road manager. According to the invention, the intervention strategy is generated based on multi-source data acquisition, processing, analysis and decision, so that the vehicle driving safety and the road management efficiency are improved.
本发明涉及交通安全管理技术领域,具体为一种车辆异常驾驶识别预警方法及系统;首先实时获取车辆位置、速度、方向及驾驶员操作数据,随后采用自适应分段聚类的平滑去噪方法对时间序列数据进行修正,并通过标准化与信息确认码生成,然后对多源数据进行加权融合,提取车速变化率、车道偏离度及驾驶员行为特征关键指标,通过设定阈值识别异常驾驶行为并分级,计算综合异常分数,并根据异常分数与设定阈值的比对结果,策略决策模块生成针对轻微、中等和严重异常的分级干预策略,最后结合车辆内部自动干预与道路管理者的全局协调干预。本发明通过基于多源数据采集、处理、分析与决策生成干预策略,从而提升车辆驾驶安全性及道路管理效率。
