It is important to maintain a known quality in the test data. For many years, VTI has tested and made comparative measurements of profilometers that are used when making road condition inventories and for functionality tests of surface designs.
VTI has carried out assignments as a part of international projects, for the Swedish and Finnish Transport Administrations, the German Federal Highway Research Institute (Bast) as well as users and manufacturers of measuring equipment.VTI is in possession of a number of pieces of equipment that can be used as reference, and well thought out methods have been prepared for how these tests should be done.
Achieving the national and international environmental objectives for maritime airborne emissions requires a combination of new and more powerful policy instruments. The policies already in place are not enough. This is one of the conclusions of a research...
Large, electrified aircraft is far off in the future. On the other hand, there may be potential for a new market with smaller regional flights. These are the conclusions of a literature survey made by researchers at VTI.
The need for standardisation is increasing as electric road systems are reaching higher levels of maturity. A large part of the standards for intelligent transport systems (ITS) assessed in a new VTI and SIS study was considered potentially useful for...
Although we know that tyre and road surface wear generates significant emissions of microplastic particles, knowledge about them is very limited. This is the conclusion of a report issued by the Swedish National Road and Transport Research Institute (VTI).
The effect of climate change will result in more extreme weather events causing for example increased risk of floods, and landslides, which will result in great costs to society. Therefore, society needs to prepare for the consequences brought on by climate...
VTI has developed a train simulator that has become a valued tool in train driver education and research on how simulators can be used to improve railway technology.
