Road dust is an important contributor to airborne particle pollution, especially in the Nordic countries where high road sur-face wear, due to studded tyre useas well as winter maintenance and operations including sanding and saltingare important contributors.Even though the road dust problems are similar, the countries have tackled different parts of the problem with different research approaches, resulting in a complex knowledgebase in need of compilation. A former project, NORTRIP, started this work and implemented the knowledge into an emission model with a specially elaborated road dust focus. The model work has been used to identify knowledge gaps, intended to be filled within the NorDust project.Laboratorytests andcontrolled and uncontrolled field measurements as well as parametrisation and modelling has been used as tools to find, de-scribeand implement issues concerning road dust formation, suspension and dynamics and road operation effects on emis-sions in facilities and sites in Finland and Sweden. The NORTRIP model has been implemented and evaluated in Iceland, not previously involved in the model development, to identify input data needs.The project has resulted in an array of findings, of which some have beenpossible to implement in new parametrisations in the NORTRIP model. In the complex research area of road dust dynamics, the project has also resulted in a lot of practical experiences concerning experimental and meas-urement designs and evaluation possibilities that future research will be able to benefit from.

VTI part of Swedish-Indian collaboration for increased traffic safety

More than 150,000 traffic-related fatalities occur annually in India. Cooperation between Swedish and Indian companies and institutions is now being formed to greatly reduce these. The lessons learned will be utilized for development needs in different parts...


Cherish the support for congestion charges

The introduction of a congestion charge in Stockholm had the intended effect of reducing congestion - even long term.  And after the introduction of the charges the public support steadily increased. This success story has attracted extensive interest from...


The Pedestrian Perspective in new projects

Two projects focusing on safety for pedestrians have recently commenced at VTI: Smart Urban Traffic Zones and Safety for Pedestrians. There are links to the ongoing EU project VIRTUAL – for which Research Director Astrid Linder is the coordinator.


Improved lighting for pedestrians and cyclists

Together with Lund University, researchers from VTI will study how outdoor lighting can improve the quality of walking and cycling trips at dusk and darkness.


VTI and SAFER are organising the world’s largest traffic and transport psychology conference in Gothenburg

In August 2020, VTI and SAFER are organising the International Conference on Traffic and Transport Psychology (ICTTP) in Gothenburg. ICTTP is held every four years, and this year is the seventh conference.


Kilometre tax is expected to have the greatest environmental impact

How can environmentally differentiated charges and other policy instruments reduce the freight transports' environmental impact? VTI has participated in a research project on this subject.
