高速公路气象服务技术及应用

气象条件对高速公路的安全出行有很大的影响,通过对高速公路交通气象服务所需的常规地理信息和相关气象数据进行分析和整理,利用插值算法将能见度、降水、温度、风速等气象要素进行了空间化处理,并整理了整个数据处理流程。基于GIS的空间分析对气象要素在高速路段上的投射技术进行了研究,并将成果数据用JSON格式在数据库进行统一存储。对交通气象服务技术的应用进行了探讨,形成了交通气象指导预报产品,在交通气象导航的应用也进行了尝试,改善了交通气象服务的效果。

Technology and Application of Highway Meteorological Services

Weather conditions have a great impact on highway safety. GIS data and meteorological data needed for highway meteorological services are analyzed and processed. Using the interpolation algorithm and meteorological elements, including visibility, precipitation, temperature, and wind velocity, are processed spatially, and the whole data processing flow are sorted. The techniques of projecting meteorological factors on the high speed sections are studied by means of the GIS based spatial analysis. The results of the operation are stored in a database in JSON for traffic meteorological services. The application of the meteorological service technology is discussed, and traffic weather forecast guidance products are produced. The application to meteorological navigation in transportation is also attempted, which improves the effectiveness of traffic meteorological services.
