Road meteorological tests mainly monitor the deterioration of road environmental quality caused by rain, snow, fog, dust and natural disasters. The test content mainly includes wind speed, wind direction, visibility, precipitation, ambient temperature and humidity, and road surface conditions. It is of great significance to detect the adverse factors that may be caused by climate change due to climate change, and to prevent the occurrence of traffic events. The automatic weather system provided by Vaisala Finland is suitable for highways, urban roads and airport runways, and provides the monitoring and management with all necessary road weather information: wind speed/wind direction, visibility, current weather phenomena, precipitation/snowfall, Atmospheric temperature, relative humidity, road surface conditions, etc. Management can use these road weather information to alert the public; make decisions to open or close the road; or perform snow removal and deicing on the road.
