Research
Traffic safety, 30 km/h areas - connection between design and behaviour
Traffic safety modelling, predictive accident models

Ongoing project

• Safety effects of allowing two-way biking on one-way streets
• Evaluation of the speed limits 40 and 60 km/h
• Safety performance for pedestrians and bicyclists
• Dimensionerande körfältsbredder
• Tech-Clinics - Promoting transportation as a job market
