The ability to make structured decisions about the optimal funding for operation, maintenance and renewal of roads and railways is currently limited. This creates significant risks that the funds are used in an inefficient manner. It is therefore important that the Swedish Transport Administration develops a transparent model for decision support in this field. VTI has undertaken a review of the state of knowledge in various areas required to bring about an economic analysis of operation, maintenance and renewal. The review shows that there are good prospects to produce a decision basis within a relatively short time. This makes it possible to answer at least some of the issues formulated. The review indicates that there are great opportunities to move forward both in road and railway areas. Five specific projects have been suggested, of which three are short term and two are long term. The aim in the long run is to make transparent and structured decisions on funding needed from an economic perspective on various road and railway sections.



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.
