MARWIS is the first road and runway weather sensor detecting road conditions, temperatures, friction, and other parameters mobile and in real-time from driving vehicles.
The mobile road weather sensor MARWIS turns vehicles into driving weather stations by detecting several critical road and runway weather parameters. It can be installed on vehicles with a distance of 1 - 2 m above the surface and delivers information about temperatures, waterfilm heights, dew points, road conditions (dry, moist, wet, snow, ice), ice percentages, relative humidity, and friction with a frequency of up to 100 times per second and a max. output rate of 10 Hz. It serves as important decision support with regard to preventive gritting. Due to the open interface protocols, MARWIS can be easily integrated into existing winter maintenance monitoring networks. Similarly, the mobile road sensor can communicate directly with the control system on gritting vehicles. The measurement data output supports the protocol UMB binary.
