Abstract:
This paper analyzes the variation law of the icing frequency of each highway section with the temperature, using the observed 10 min air temperature and road surface tmeperature from 87 traffic and weather stations, established since 2013, along the highway in Hubei Province. It is found that the Logistic regression models are satisfied, but the ambient temperatures corresponding to icing in different highway sections are different. By studying the temperature condition probability of the road icing in each highway section, we obtain the temperature turningpoint of each section of Hubei highway. Combined with the precipitation (snow) of each highway section, it can be used for the early warning of highway icing in Hubei Province. Thus, suggestions can be made for whether to carry out ice removal measures of highways and when to carry out ice removal measures.
