Dynamisk prognosstyrd vintervägdrift: Fas 2

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.



Global Public Transport Summit

Vision Zero for Sustainable Road Safety in the Baltic Sea Region

The second Vision Zero for Sustainable Road Safety in the Baltic Sea Region conference will be held in Tallinn, Estonia. VTI is part of the programme committee. 



How vehicles can avoid accidents on newly paved roads

Friction is an important property for road safety. VTI has investigated how roads change in the first few weeks after surfacing work has been completed. Researchers recommend posting warning signs when the road is opened and waiting at least three weeks to...


VTI contributes to study on older drivers and accidents

On behalf of and in collaboration with the Swedish Transport Agency, VTI has carried out a study of older drivers and the link between illness and traffic accidents. The Transport Agency has now published the results.


VTI in research programme Triple F (Fossil Free Freight)

VTI is part of the consortium that has been commissioned by the Swedish Transport Administration to conduct a research programme with focus on fossil-free freight transports. The programme, called Triple F, will run for 12 years. Part of the programme is...


Several actors collaborating on HCT vehicles

The increasing amount of freight, congestion on the roads and environmental emissions are problems that high capacity vehicles, HCT vehicles, can contribute to solving.


VTI’s simulators are being used for emergency vehicles

Better accessibility and shorter response times for emergency vehicles – this is something that standardised, directed, traffic messages, transmitted over the 5G network can contribute. Within the EU project Nordic Way 2, a functioning prototype of such a...


Modal shift - a way to achieve the environmental objectives

Shifting freight transports from road to rail and water can contribute to achieving the Swedish environmental and climate objectives by 2030. How this could be done is something that VTI researchers and researchers from Gothenburg University are investigating...
