The invention provides an urban road meteorological condition prediction method fusing vehicle-mounted and fixed meteorological stations, and the method comprises the following steps: 1, building a data sharing network of a mobile vehicle meteorological station and a fixed meteorological station through an Internet of Vehicles technology, and carrying out the collection of meteorological data through the data sharing network; and step 2, establishing a meteorological condition prediction module based on a meteorological station, performing data preprocessing and analysis, and completing prediction of urban road meteorological conditions based on a long short-term memory network and a graph convolutional neural network. The method aims at solving the problem that the prediction precision is not high due to the fact that the number of traditional fixed meteorological stations is insufficient, and can cover a wider urban road network. By combining the layout scheme of the mobile vehicle-mounted weather station and the fixed weather station, the method has high adaptability and expandability, and can flexibly meet different road traffic network requirements. In addition, deployment and adjustment can be carried out according to actual application conditions so as to meet the requirements of various road meteorological condition prediction tasks.

    本发明提供了一种融合车载和固定气象站的城市道路气象条件预测方法,包括以下步骤:步骤1,利用车联网技术建立移动车气象站和固定气象站的数据共享网络,通过数据共享网络进行气象数据采集;步骤2,建立基于气象站点的气象条件预测模块,并进行数据预处理和分析,基于长短期记忆网络和图卷积神经网络,完成城市道路气象条件的预测。该方法旨在解决传统固定气象站数量不足而导致预测精度不高的问题,并能够覆盖更广泛的城市道路网络。通过结合移动车载气象站和固定气象站的布设方案,该方法具备高度适应性和可扩展性,能够灵活应对不同的道路交通网络需求。此外,还可以根据实际应用情况进行部署调整,以应对各种道路气象条件预测任务的需要。
