Unpredictable weather, short time frames and requirements of high quality can make a challenge of the winter road maintenance. The pressure on both operating staff and machine drivers is very high during periods. The road climate can vary greatly within one and the same operating area and there is a need to adjust for these variations to maximise efficiency.

The project "Dynamic Forecast Controlled Winter Road Maintenance" has been aimed at developing a solution to simplify the handling of data flows from road weather forecasts and simplify decisions for the winter maintenance contractor what actions are needed and where they are needed. This has been done with data from road weather forecast services together with the existing road network in the operating area, the actions have been optimized for the available numbers of vehicles to create dynamic actions for a more productive and sustainable winter road maintenance.

Two phases of the project have now been completed and the purpose and goal of streamlining operations through interconnected data flows has been achieved. In connection with this, a dynamic forecasting route optimisation product has also been developed. The project showed that using a dynamic forecasting route optimisation, is it possible to carry out the full potential of the decision support systems through automation. The potential of using forecast-based winter road maintenance is great, both for the customers and for the individual operating contractor. The contractor benefits from it in the operational work, improves the working environment and reduces costs. However, environmental impact also decreases, and in the long term, it also reduces the social economic costs of road maintenance. It is important to emphasise that the technology enables the safety factor on the road to not be reduced despite savings of salt and action times.
