The invention relates to a road traffic intelligent risk early warning method, system, device and medium, and the method comprises the steps: building a vehicle driving risk prediction model and a vehicle safety grading model based on periodically collected historical trajectory data, and building a vehicle risk early warning system; before the vehicle enters the safety early warning area, factors influencing the vehicle accident risk probability are obtained, the self safety level of the current vehicle is predicted according to the vehicle safety grading model, and the safety early warning threshold value of the current vehicle is matched according to the self safety level of the current vehicle; after the vehicle enters the safety early warning area, the safety state of the current vehicle is judged according to the vehicle driving risk prediction model and the safety early warning threshold value of the current vehicle, real-time early warning is carried out, and early warning information is issued; and dynamically correcting the vehicle driving risk prediction model, the vehicle safety grading model and the threshold division in the vehicle risk early warning system every preset period. The method can be widely applied to the technical field of vehicle safety early warning.

    本发明涉及一种道路交通智能化风险预警方法、系统、设备和介质,包括:基于周期性采集的历史轨迹数据,构建车辆行车风险预测模型及车辆安全分级模型,并搭建车辆风险预警系统;进入安全预警区域前,获取影响车辆事故风险概率的因素,并根据车辆安全分级模型预测得到当前车辆的自身安全等级,根据当前车辆的自身安全等级对当前车辆的安全预警阈值进行匹配;进入安全预警区域后,根据车辆行车风险预测模型及当前车辆的安全预警阈值判断当前车辆的安全状态进行实时预警,并发布预警信息;每间隔预设周期,对车辆风险预警系统中的车辆行车风险预测模型和车辆安全分级模型、阈值划分进行动态修正。本发明可以广泛应用于车辆安全预警技术领域。
