The invention discloses an early warning method and system for driving of vehicles in sudden collapse of an expressway under severe conditions, and relates to the field of road traffic data analysis, the early warning method for driving of vehicles in sudden collapse of the expressway under severe conditions mainly comprises the following steps: obtaining vehicle information, historical expressway data and meteorological environment data of a target expressway section; obtaining a risk level by using the historical high-speed data, the meteorological environment data, the real-time high-speed data and the prediction model; according to the surrounding vehicle information, performing abnormity judgment and event single occasional judgment to obtain reminding information; according to the reminding information, vehicle stopping information and vehicle stopping sensor permission are obtained; and obtaining a danger range by using an information fusion technology according to the stopping vehicle sensor permission. According to the early warning method and the early warning system for the vehicle running in the sudden collapse of the expressway under the severe condition, the range and the advance of road safety early warning can be improved.

    本发明公开了一种恶劣条件下高速公路突发塌方车辆行驶预警方法及系统,涉及道路交通数据分析领域,恶劣条件下高速公路突发塌方车辆行驶预警方法,其步骤主要包括:获取目标高速路段的车辆信息、历史高速数据和气象环境数据;利用历史高速数据、气象环境数据、实时高速数据和预测模型,得到风险等级;根据周围车辆信息进行异常判定和事件单一偶发性判定得到提醒信息;根据提醒信息,得到停止车辆信息和停止车辆传感器权限;根据停止车辆传感器权限,利用信息融合技术,得到危险范围。实施本发明提供的恶劣条件下高速公路突发塌方车辆行驶预警方法及系统,能提升道路安全预警的范围和提前量。
