基于WebGIS技术的精细化高速公路气象服务系统

Precise Highway Weather Service System Based on WebGIS Technology

根据交通气象服务的特点,研究开展高速公路交通气象服务的思路和技术方法。通过研究高速公路交通气象观测网组网原则及站点选择规则,建成交通气象观测网。采用降水、能见度、路面温度、大风等高影响气象因子,建立高速公路通行气象条件模型,根据基础地理数据、气象监测实况数据、精细化模式集成预报数据、灾情调查等数据,利用Flex Builder 4. 6为开发工具,设计开发了一套基于Web GIS技术的以精细化预报为核心的交通气象灾害监测预警服务系统。该系统实现了对高速公路的实况天气监测、精细化数值天气预报及灾害性天气预警三大功能,实现了全自动、智能化的精细化服务模式,为用户提供直观的服务信息,为公众交通出行提供了及时的气象服务。研发的公路交通气象服务系统已正式对外服务,并在春运期间为公众用户便捷、安全出行提供了保障。

Based on the characteristics of traffic weather service, the ideas and techniques of highway traffic weather service are studied. By studying on the principles and site selection rules of highway meteorological observation network, the traffic meteorological observation network was established. Using high impact factors such as precipitation, visibility, pavement temperature and strong wind to establish a model of highway meteorological conditions, based on basic geographic data, meteorological monitoring data, the precise model integrated forecasting data, the disaster investigation data and so on, using Flex Builder 4.6 as a development tool, the highway traffic weather service system based on WebGIS platform was designed and developed. The system has three functions of real weather monitoring, precise numerical weather forecasting and severe weather warning, realizes the automatic, intelligent precise service mode, for the users and public traffic travel, provides an intuitive and timely weather services. The system had been officially in services and provided guarantee for the convenience and safety travel of public during the Spring Festival.
