摘要
针对东北地区冬季高速公路没有大规模铺设结冰检测装置,也没有可实行的道路结冰预警等级标定技术的现状,无法及时有效的发出道路结冰预警信号,进而影响道路运输效率和交通路网的运行状况。通过分析气象因子和多个影响因素,借助气象数据和相关数据建立了道路结冰预警信号的等级标定模型。通过验证数据集的检验,发现模型具有有效性,可以为完善道路结冰预警信号的定量分级标准提供参考。
There is neither large scale ice detection facility nor road icing warning level calibration technique available to be used in freeway infrastructure in Northeastern China. This situation makes it impossible to issue road icing warning level signal timely and effectively,furthermore it will affect the transportation efficiency and the operation of road network. In this paper,the authors developed the level calibration of road icing warning signal by analyzing meteorological data and relative data. The authors tested the model using the valid dataset,and found that this model was valid and could be valuable to improve the national standard of quantitative classification of road icing warning signals.
