This report summarise the experiences so far of using Stated Preference surveys on the Internet to find passengers preferences. TØI has carried out analyses of whether the data collection methods used affects the results. The analyses identify whether those who choose to use the Internet have preferences which are different to those who choose paper-based or home-based interviews, or whether it is the form of the interview which affects the results. In addition, we present key characteristics of those who choose the Internet and those who choose paper-based/ home-based interviews.
