The study comprises time effect for private and business personal trips. The basic theoretical approach is that Value-of-Time (VoT) for private trips should be based on the tradeoffs of individuals, whereas the VoT for business trips should include the value to the individuals as well as productivity effects. However, two additional studies to further investigate effects of travel time changes for business trips were also carried out. The purpose of the first one was to provide behavioural VoT's and the purpose of the second one was to specifically study the valuations for self-employed persons, who are supposed to consider individual as well as productivity effects in their valuations of travel time changes. Based on previous experience and recommendations from earlier VoT studies in the UK and in the Netherlands, the Stated Preference technique was chosen as the primary analytical tool. Starting in November 1994, the main field work was carried out, giving some 5000 interviews distributed on car, air, long distance train, long distance bus, regional train and regional bus. The analysis work started in December 1994, and in March a basis for evaluation guidelines was completed. The paper reports on the design of the study, the analytical results and on the conclusions in terms of application guidelines. (A) For the covering abstract see IRRD 880168.
