摘要
高速公路交通对气象条件高度敏感,交通气象服务在保障交通安全等方面具有重要作用。梳理了高速公路交通气象服务所需的气象数据、基础地理信息数据等的具体内容和获取方式,利用插值算法和GIS空间分析技术进行气象要素空间化和高速公路路段投射,最后对高速公路气象要素预报、基于影响的预报预警服务产品等方面的应用进行了探讨。
Highway traffic is highly sensitive to meteorological conditions, and traffic weather services play an important role in ensuring traffic safety. In this paper, the specific content and acquisition methods of meteorological data and basic geographic information data required for highway traffic meteorological services are sorted out. The interpolation algorithm and GIS spatial analysis technology are used to study the spatialization of meteorological elements and the projection of high-speed road segments. Finally, the application of highway meteorological element forecasting and impact-based forecasting and warning service products was discussed.
