The basic aim of TU is to survey the transport behaviour of Danes residing in Denmark.
The survey is managed by DTU Transport on behalf of a group of Danish authorities and organisa-tions. Thus, we focus on the needs arising from this group:
• A stable, continuous, operational, reliable, easy-to-comprehend survey
• Often very detailed, but generally not very advanced analyses
• Data which cannot be drawn from other sources
We survey behaviour, not attitudes, nor what is considered “normal”. The basic content of the ques-tionnaire is a one-day diary combined with various background questions.
