摘　　要：应用移动式交通气象环境监测系统对固定式交通气象监测站所在路段进行路面温度数据采集,研究不同天气条件下高速公路路面温度数据时空修正处理方法,绘制相对路面温度分布图,掌握路段中不同位置与监测站点的相对路面温度差异,推算得到监测站点以外同一时刻其他位置的路面温度,实现高速公路全路段路面温度的实时监测.提出适用于高速公路路面温度数据采集、融合处理、描述展现的流程和方法,允许误差在±1℃范围内,准确率达到92.31%.可为监测高速公路长距离路段的路面温度、辨识路面低温或易于结冰区域以及提升冬季结冰风险路段的高速公路运营管理、养护决策和应急服务水平提供技术参考.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.
