The Swedish National Road and Transport Research Institute (VTI), is an independent and internationally prominent research institute in the transport sector. Our principal task is to conduct research and development related to infrastructure, traffic and transport. Our operations cover all modes of transport, and the subjects of pavement technology, infrastructure maintenance, vehicle technology, traffic safety, traffic analysis, users of the transport system, the environment, the planning and decision-making processes, transport economics and transport systems. VTI conducts commissioned research in an interdisciplinary organization. Employees also conduct investigations, provide counselling and perform various services in measurement and testing.
The institute has a wide range of advanced research equipment and world-class driving simulators, and is an assignment-based authority under the Ministry of Enterprise, Energy and Communications. The institute holds the quality management systems certificate ISO 9001 and the environmental management systems certificate ISO 14001. We have about 200 employees and are located in Linköping (head office), Stockholm, Gothenburg, Borlänge and Lund. From a road user perspective, the institute conduct research on mobility, accessibility, behaviour and attitudes, especially considering travellers’ physical, mental, social and societal aspects. VTI also conducts research on vehicle design, infrastructure and traffic environments on the basis of road users’ and travellers’ different needs. Road user research is to a great extent applied research and VTI have access to very good experimental resources, for example advanced driving simulators, instrumented vehicles for studies in real traffic, and a physiology laboratory. The research is often carried out in collaborative projects with stakeholders in Sweden and in other countries.
VTI has an extensive experience in research on driver state and has carried out experiments involving fatigue, distraction, alcohol and medicines. VTI has a unique governmental approval to perform experiments with impaired drivers on real roads. VTI holds the Quality management systems certificate ISO 9001:2008 and the Environmental management systems certificate ISO 14001:2004.
