Analysis of Temperature and Humidity Changes in Winter on Highways in High Altitude Mountainous Areas and Prediction Model for Road Ice Formation
The changes in winter temperature and humidity data of highways in plateau mountainous areas are studied,and road surface icing prediction models are analyzed.The results show that:(1)the changes in road surface temperature and humidity are basically the same as those in atmospheric temperature and humidity,with a difference temperature of about 1℃ and a humidity of about 5％,which confirms the feasibility of using road surface temperature and humidity to analyze road surface icing status.(2)The time of road icing and the corresponding road temperature and humidity data are analyzed,the theory of using intelligent temperature and humidity data to predict road icing as well as road icing warning information is proposed.(3)A prediction model for road surface icing is established,and the threshold values for the winter road surface icing prediction model in plateau mountainous areas are proposed,providing reliable data support for intelligent maintenance decision-making in winter.
