The invention discloses a multi-mode real-time traffic early warning generation method and device, equipment and a medium. The method comprises the following steps: performing classification prediction on road traffic risks based on first traffic condition data collected by edge end equipment to obtain a first early warning probability sequence corresponding to the edge end equipment, and performing classification prediction on the road traffic risks based on second traffic condition data collected by decision end equipment to obtain a second early warning probability sequence corresponding to the decision end equipment; and then fusing the first early warning probability sequence and the second early warning probability sequence to obtain a target fusion feature, and then performing regression prediction on the road traffic risk according to the target fusion feature to obtain comprehensive traffic early warning information. Under the condition of combining early warning probability sequences at the two ends, the probability of traffic accidents can be effectively and reasonably reduced, the traffic intelligence level is improved, and meanwhile the road utilization rate is effectively improved.
本发明公开了一种多模态实时交通预警生成方法、装置、设备和介质。基于边缘端设备收集的第一交通情况数据对道路交通风险进行分类预测得到边缘端设备对应的第一预警概率序列,基于决策端设备收集的第二交通情况数据对道路交通风险进行分类预测得到决策端设备对应的第二预警概率序列,接着将第一预警概率序列与第二预警概率序列进行融合,得到目标融合特征,然后根据目标融合特征对道路交通风险进行回归预测,得到综合交通预警信息。在结合两端预警概率序列的情况下,可以有效和合理地减少交通事故的发生几率,提升交通智能水平,同时有效提升道路利用率。
