Norway, Sweden and Denmark all have national travel surveys. The network aims to encourage collaboration between the Nordic countries to better handle the methodological challenges in national travel surveys.
The surveys are in many aspects similar and have to handle many of the same methodological challenges among others:
- Falling response rates
- Selection bias
- Implementing new technology such as mobile phone applications
- Organizing and financing of the surveys
