Results obtained from travel behaviour studies are used to document the time-dependence of behaviour changes and to study effects of specific measures in transportation systems. This may involve the introduction of urban rail transits or other measures affecting transportation demands, such as toll road systems. Data gained by travel behaviour studies form the basis for transport models used in transport planning. SINTEF has extensive experience conducting travel behaviour studies. Our organization has received acknowledgment for our expertise in processes governing transportation needs and travel behaviours. SINTEF also actively developing new data acquisition techniques for travel behaviour studies by utilizing new and innovative technologies.
