The present study compared the driving behaviour of older (67+) drivers who either drove throughout the year or only during the summer season. 41 older subjects drove in VTI’s simulator in both winter and summer conditions, partly combining the driving task with a secondary task of visual detection. It was hypothesised that the groups would differ as to their driving behaviour and that any differences would be more pronounced during winter conditions. While the groups did differ with respect to stress experienced in traffic (more for those driving in summer only) and to cognitive status (only in males, lower for those driving in summer only), there were practically no differences in their driving behaviour. The conclusion is that the strategic limitation of driving exposure either had not affected their driving behaviour or that the differences were too subtle to be detected in a simulated driving situation.



Millions for research into maritime transport and the environment

Maritime transport is a major source of emissions of harmful air pollutants and carbon dioxide. In a new project, a research team from the Swedish National Road and Transport Research Institute (VTI) and the University of Gothenburg has received SEK 6.4...


New research programme for more efficient travel

The Swedish National Road and Transport Research Institute (VTI) is playing an important role in a major new research programme to find radical solutions leading to fewer trips and more efficient travel, along with tools to enable better use of roads and...


Simulator used to practice emergency responses safely

Emergency responses of the police, ambulance, and rescue services are associated with a high risk of accidents, but practicing them in real traffic is neither safe nor permissible. A simulator-based method developed by the Swedish National Road and Transport...


Simulation of cut-in by manually driven vehicles in platooning scenarios

A study in a VTI-driving simulator has showed that a platoon will be able to handle a cut in from a manually driven car. The results of this study have recently been presented at two conferences in Japan.

Self-driving buses in Sweden next year?

A self-driving, fossil-free bus. This idea might become reality through a forthcoming collaborative project involving the Swedish National Road and Transport Research Institute (VTI), Linköping University and several other participants. The project group aim...
