摘要
高速交通的安全运行与气象条件密切相关,交通气象服务在保障交通安全等方面具有重要作用。通过对交通气象服务所需的地理信息数据和气象数据进行了分析和整理,利用插值算法和GIS技术,将能见度、降水、温度、风速等气象要素通过插值进行了空间化处理,通过空间分析对气象要素在高速公路路段上的投射技术进行了研究,并将运算结果用空间数据库进行统一存储,以便交通气象服务调用。在交通气象指导预报、交通气象导航等方面的应用进行了探讨,形成了交通气象服务产品,提高了交通气象服务的效果。
The safe operation of high-speed traffic is closely related with weather conditions. Transportation meteorological services are very important in the protection of traffic safety. GIS data and meteorological data needed for meteorological traffic services are analyzed and organized. By means of interpolation algorithm and GIS technology, meteorological elements including visibility, precipitation, temperature, and wind velocity are spatial processed through interpolation. The techniques of projecting meteorological factors on the high-speed sections are studied by spatial analysis. And the results of the operation are stored in a spatial database for meteorological traffic services. The applications are discussed on traffic guidance weather forecasts and traffic meteorology navigation. The transport meteorological services and products are formed. The effectiveness of traffic meteorological services is improved.
