The survey shall, amongst other things, give information about people's travels, how and why they travel and variations in travel activity between different population groups.

Data on the population's travel activity are vital for national and local transport planning. The results are used as a basis for development of transport models, prognosis work, calculations of exposure in traffic safety work and research. The travel surveys are also important as background for evaluating results from surveys on specific means of transportation or particular geographical areas.
