The invention discloses a road icing prediction system. The system comprises an information acquisition unit for acquiring air temperature Qn, relative humidity Ra, wind speed V and traffic flow; and the data processing unit is used for calculating the data acquired by the information acquisition unit and generating early warning information. According to the method, the obtained traffic flow information is extracted, small cars, non-motor vehicles and trucks are defined respectively, the non-motor vehicles are removed, the flow of the small cars and the flow of the trucks are calculated, the road surface temperature Ts is calculated, a road icing equation is constructed, and a result is output.
本发明公开了一种道路结冰预测系统,包括:信息获取单元:获取空气温度Qn、相对湿度Ra、风速V以及车流量;数据处理单元:对信息获取单元获取的数据进行计算,并生成预警信息。本发明中,对获取的车流量信息进行提取,分别定义小型汽车、非机动车与货车,并剔除非机动车,计算小型汽车流量与货车流量,计算路面温度Ts,构建道路结冰方程,并输出结果。
