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.
The Government has commissioned VTI to develop and disseminate knowledge regarding the emission of microplastics from road traffic.
The road infrastructure must be prepared for self-driving vehicles – especially in the beginning when the concepts are still new. Researchers are contributing to this through CoEXist, an EU-funded research project in which VTI participates as the largest...
VTI employees recently arranged a workshop in Brussels on the standardisation of Electric Road Systems (ERS). ERS has become increasingly relevant as a possible method for reducing the transport sector's environmental impacts, especially in terms of climate...
Shift2Rail is a European railway project that works actively to create innovations within the railway sector. IMPACT-2 is a project within Shift2Rail that follows and evaluates the innovation projects. How are the innovations coming along? Are they beneficial...
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...
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.
