16. Winter Road Maintenance using Renewable Thermal Energy
Sammanfattning : Winter road maintenance is costly but it is inevitable since it is necessary to keep roads accessible and safe during winter. Current winter road maintenance methods use annually 600 000 tons of salt, in the Nordic countries. The salt ends up in the environment along the roads and results in environmental challenges.

17. Smart pavement maintenance and infrastructure operation through digital twins : Case study for Norvik Port, Sweden
Sammanfattning : There is an urgent need to make the way in which people and goods move more sustainable. Though pavements are one of the key components of road transportation networks and logistics systems, they are usually overlooked in systemic sustainability analyses. LÄS MER
18. Predictive models for accidents on urban links - A focus on vulnerable road users
Sammanfattning : Much of earlier work on predictive models for accidents has been focused on rural traffic or urban intersections. This work has aimed at identifying and investigating possible improvements to predictive models for accidents on urban links. A special focus has been on the accidents of vulnerable road users.

19. Ice free roads using hydronic heating pavement with low temperature: Thermal properties of asphalt concretes and numerical simulations
Sammanfattning : A traditional method to mitigate the slippery conditions of a road is to spread out salt and sand on the road surface. However, salting causes corrosion on the road infrastructures, damage to surrounding vegetation and salification of fresh water. Hence, there is a need for alternative solutions to mitigate the slippery conditions. LÄS MER
20. Large-Scale Road Network Vulnerability Analysis
Sammanfattning : Disruptions in the transport system can have severe impacts for affected individuals, businesses and the society as a whole. In this research, vulnerability is seen as the risk of unplanned system disruptions, with a focus on large, rare events. LÄS MER
