Collecting weather data as we drive is not new. Many vehicles today display the air temperature outside as we drive; however, for transportation authorities this is not enough. Snow plows and gritters can be equipped with air temperature, pavement temperature, and moisture sensors, to provide much more information about the road weather as they move and conduct operations.
For the most part this data was only available to the driver themselves or maybe the vehicle was equipped with some sort of data recorder for analyzing the data upon their return. Now with the ever increasing coverage and reduced cost of communications, agencies can transmit the data along with the vehicles coordinates, so that decision makers have an even better understanding of the surface weather. Ministry or government vehicles of all types can be equipped with sensors and communications systems, allowing for a huge network of mobile data filling in the gaps for the fixed road weather stations.
Vaisala offers several mobile sensors specifically designed for mobile applications. The Vaisala sensors allow for in-vehicle display or connection to a mobile vehicle communication network.
