摘要
通过分析暴风雪天气对交通的影响,建立暴风雪预警体系,将暴风雪预警分为灾前和灾时预警两个连续过程。其中灾时预警采用显式预警方法,选取降雪量与其对高速公路交通的影响,依据Fisher判别法则建立暴风雪预警级别判别模型,并提出暴风雪实时预警级别判别评价方法。通过实例验证了暴风雪预警级别判别模型的可靠性,进一步证明该模型可用于高速公路暴风雪预警级别判别,可以为保障暴风雪天气下高速公路安全运营提供技术参考。
According to the research on the impact of stormy weather on traffic,the snow storm warning principle has been established,which is divided into 2 periods,which are pre-disaster warning and real-time warning.For the real-time warning,it has been established by explicit warning method and the Fisher distinguishing law based on the effect of snowfall to traffic.At last,the reliability of the discrimination of expressway storm warning level model is verified by using an example application;further more,it is proved that the model can be used for the discrimination of expressway storm warning level,which provides technical reference to guarantee the safe operation of expressway under snowstorm weather.
