Air quality research at VTI focuses on emissions of air pollutants from the transport sector. Field and laboratory measurements are used within national and international research projects. One important field concerns wear particles from road and railroad traffic. The emission process and the characteristics of the aerosol particles emitted are thoroughly investigated with respect to health standards and toxicity. The aim of the research is to understand why and how the particulate matter is hazardous to human health and which abatement strategies which are efficient for lowering the emission.


Freight train model for real-time simulation

In an attempt to increase the freight transport capacity in Sweden, introduction of longer and heavier trains is investigated. To aid this investigation, a freight train simulator was designed and constructed. Here, the implemented freight train...

Required friction utilization for friction estimation on wet asphalt, an experimental...

Real-time information about the friction coefficient between the tyre and the road can be used to improve active safety systems and is an enabler for autonomous vehicles. Large tyre force excitation is normally required to obtain an accurate...

Moderna betongbeläggningar: utveckling mot mindre slitage och partikelemission

Road paving of concrete has the potential to be an interesting alternative to asphalt in several ways. Concrete is normally durable and lacks fossil components, which is favorable from a climate point of view and for fire safety in e.g. tunnels....

ICTTP 2020

ICTTP, International Conference on Traffic and Transport Psychology, is held in Gothenburg, Sweden.



VTI contributes to study on older drivers and accidents

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.


VTI in research programme Triple F (Fossil Free Freight)

VTI is part of the consortium that has been commissioned by the Swedish Transport Administration to conduct a research programme with focus on fossil-free freight transports. The programme, called Triple F, will run for 12 years. Part of the programme is...


Several actors collaborating on HCT vehicles

The increasing amount of freight, congestion on the roads and environmental emissions are problems that high capacity vehicles, HCT vehicles, can contribute to solving.


VTI’s simulators are being used for emergency vehicles

Better accessibility and shorter response times for emergency vehicles – this is something that standardised, directed, traffic messages, transmitted over the 5G network can contribute. Within the EU project Nordic Way 2, a functioning prototype of such a...


Modal shift - a way to achieve the environmental objectives

Shifting freight transports from road to rail and water can contribute to achieving the Swedish environmental and climate objectives by 2030. How this could be done is something that VTI researchers and researchers from Gothenburg University are investigating...


Report regarding government commission on the costs of traffic to society has been submitted

Since 2013, the Swedish National Road and Transport Research Institute (VTI) has had several government commissions to produce documentation on the costs to society caused by traffic. On 1 November 2018, the agency reported its latest commission, Samkost 3....
