This report deals with a concept applying residual value estimations to applications in optimisation and procurement of road construction and maintenance. The purpose is to develop a framework and concept for tieing together technical and economical considerations in order to contribute to more optimised construction and maintenance of roads in a long-term perspective. This report is limited to investments in the pavement. Initially, the term residual value and its application in this context is investigated. Then, possibilities for prediction of pavement deterioration and performance are presented. These models are also linked to prediction of maintenance needs. Finally, a concept for cost predictions is developed with corresponding residual value applications, for example performance procurement, payment models, as well as more optimised pavement management from a life cycle perspective.



Millions for research into maritime transport and the environment

Maritime transport is a major source of emissions of harmful air pollutants and carbon dioxide. In a new project, a research team from the Swedish National Road and Transport Research Institute (VTI) and the University of Gothenburg has received SEK 6.4...


New research programme for more efficient travel

The Swedish National Road and Transport Research Institute (VTI) is playing an important role in a major new research programme to find radical solutions leading to fewer trips and more efficient travel, along with tools to enable better use of roads and...


Simulator used to practice emergency responses safely

Emergency responses of the police, ambulance, and rescue services are associated with a high risk of accidents, but practicing them in real traffic is neither safe nor permissible. A simulator-based method developed by the Swedish National Road and Transport...


Simulation of cut-in by manually driven vehicles in platooning scenarios

A study in a VTI-driving simulator has showed that a platoon will be able to handle a cut in from a manually driven car. The results of this study have recently been presented at two conferences in Japan.



The five-year anniversary of European Road Profile Users' Group (ERPUG) Forum will take place at Ramboll head quarter, Copenhagen, Denmark October 19-20, 2017.


Self-driving buses in Sweden next year?

A self-driving, fossil-free bus. This idea might become reality through a forthcoming collaborative project involving the Swedish National Road and Transport Research Institute (VTI), Linköping University and several other participants. The project group aim...
