面向公众出行的公路交通气象服务系统

Public-Oriented Highway Traffic Weather Service System

从公众公路出行前的气象服务需求出发,研究公路交通气象服务的思路和技术方法,开展公路交通监测、预报与预警气象服务。研究建立公路交通气象观测网组网原则及站点选择规则,开展基于混合空间分析技术的道路反演、路径分析等关键技术研究,综合利用能见度、天气、风3种高影响气象要素建立公路通行气象条件模型,研发实况、预报、预警3大类6种气象服务产品,为用户提供直观、有效的气象服务信息。研发的公路交通气象服务系统于春运期间通过中国天气网交通频道正式对外服务,有效促进了公众用户的便捷、安全出行。

Starting with the weather service needs of public transportation before departure, it is to study the ideas and techniques of highway traffic weather service to conduct monitoring, forecasting, and early warning. First, the highway traffic meteorological observation network principles and site selection rules for highway traffic are determined. Second, some key techniques, including the road inversion based on hybrid spatial analysis technology and route analysis, are studied. Third, integrating such high impact meteorological elements as weather, visibility, and wind, a model of highway meteorological conditions is established. The weather products of monitoring, forecasting and early warning gave the public an intuitive and effective service. The Highway Traffic Weather Service System （HTWS） began to provide service through the traffic channel of Weather China during Spring Festival of 2014, effectively promoting public＇s convenience and travel safety.
