144 Vaisala is displaying its RWS200, a road weather information system that is playing a crucial role on Finland’s Aurora Smart Road, implemented by the Finnish Transport Agency, and equipped to fit research and development needs in the field of smart transport.


Information on the road surface state is crucial for researching and developing automatisation, supported driving and maintenance in Arctic traffic.

The RWS200 is intelligently designed, with sophisticated algorithms and smart power management.  Its compatibility with various sensors makes it a complete road weather information solution.

Vaisala and the Finnish Meteorological institute (FMI) installed the RWS200 station in Muonio in November 2017 to help to monitor the state of the road surface. The station observes whether the surface is dry, wet, icy or snowy, and provides information on its temperature as well as wind and visibility conditions on the road. Data from the RWS200 is being incorporated in the Finnish Transport Agency's Digitraffic service.

The Aurora Smart Road provides an open and versatile test environment for everyone working with R&D and aiming to develop smart traffic, enabling the development of new solutions to fit the needs of smart transport, automated driving and smart road asset control.

"The RWS200 road weather station is now part of the smart infrastructure of the Aurora Smart Road that includes smart roadside markings, high resolution maps and location information” said Vaisala’s Iiro Salkari. “In addition to the smart road infrastructure, the Arctic environment and its requirements make the project unique.”

Vaisala is also a member of the international Aurora Network, in which the company looks for partners in order to develop its road weather station and services for the automated transportation of the future.
