The Norwegian road authority invests in Road Status Information, a new technology for winter road prognosis

The Norwegian road authority Norska Statens Vegvesen has invested in a new technology for winter road prognosis, Road Status Information.

The technology has been developed by Klimator and NIRA Dynamics. Klimator is a knowledge-based company in the field of applied climatology while NIRA Dynamics is focussed on research and development of signal processing and control systems for the automotive industry

RSI is software which through advanced algorithms combines the data from connected vehicles with information from roadside weather stations and weather forecasts. That makes connected vehicles rolling weather stations which transmit various signals including current road friction which is the key to determine local road grip.

RSI manages to determine the road grip conditions in real time with high precision and creates accurate 12h forecasts. This enables an increased safety on wintery roads, a significant environmental benefit and cost savings through the more efficient use of winter service resources (road salt consumption, driven miles in salt trucks, etc.).

The vehicles are connected via NIRA-developed OBD-dongles and register current position, ambient temperature, wiper activity and road friction. It takes only a few minutes to equip a vehicle and shortly after, the data is continuously available on the RSI-server.

The project started in January 2018 in Tromsö and there is much interest in the new technology. More than 300 private car owners have registered their vehicles to participate.

Big data has emerged as a game changer across all the industries. The automotive data presents many ways in which it can be utilized a lot of companies are working to set business models, use cases, and monetization options around it. The government utilizing this data for better management and improvement of infrastructure is one of the use cases.
