Abstract:

In order to realize realtime monitoring of pavement temperature of the whole expressway, continuous pavement temperature data were collected using a mobile traffic meteorological monitoring system where was fixed a traffic meteorological station, and a temporal and spatial pavement temperature data processing method was studied under different weather conditions, and a relative pavement temperature distribution map was drawn, and the relative pavement temperature difference between different positions and the fixed traffic meteorological monitoring station were obtained, and the pavement temperature at other locations were calculated. This paper shows a set of processes and methods for data collection, fusion processing, and descriptive presentation of pavement temperature, and the accuracy reaches 92.31% within allowable error range of ±1℃. All these results are in order to monitor effectively pavement temperature of long distance, identify low temperature and easy icing sections, which will provide a strong technical support for enhancing levels of operation management, maintenance decision and emergency service of icing risk sections in winter.
