VTI’s measurements make airfields safe

Håkan Carlsson is the laboratory manager for measurement technology and workshop at VTI. His role gives him responsibility for the activities, and he normally doesn't have time to take part in the practical work. However, there is one exception, and that is proof load testing for airfield bearing...

The risk of road accidents increases as more and more roads become polished

In recent years, there have been a number of serious road accidents due to motorists skidding off the road. The reason is believed to be that the country's roads are becoming increasingly smooth. VTI has investigated the cause of the problem in a pilot study. New designs of studded tyres, a rise...

Sustainable pavement

In VTI's road laboratory, test specimens of so-called ‘green’ asphalt are displayed on a bench. The asphalt is black in colour, but its properties make it better for the environment and climate than established asphalt mixtures, hence the name green asphalt. For example, the asphalt may last...

A venerable laboratory central to the development of research models

The oldest is the test road machine, which was built during World War II. It was initially used to find better solutions for gravel road constructions. Then came asphalt. The concrete coffers for the gravel road construction were turned upside down(!), and then the machine could be used to improve...

Wider roads can result in fewer accidents

In roads with only two lanes and oncoming traffic, making the roads wider can reduce traffic accidents when traffic volumes are high. Photo: Shutterstock A new TØI report Safety effects of cross section elements describes how traffic accidents are affected by different road standards....

Megatrends are shaping future streets

The streets of the future have high demands to meet, in terms of both technical design and construction. Researchers from the Swedish National Road and Transport Research Institute (VTI) are looking for smart solutions to meet four megatrends: Urbanisation, digitalisation, electrification and...

A flexible and sustainable port network by adaptive port planning

Ports are complex systems that have always been evolving to satisfy new demands for their different layers of physical infrastructure, operation and management, and products and services. Under a volatile and rapidly changing environment, addressing uncertainties in the planning process increases...
