This paper presents a project which aims to investigate passengers' valuations of travel time components where the valuations depend on timetable information, and various information sources. The project used the stated preference (SP) method, applied to three groups of people in the Stockholm region of Sweden: (1) public transport users without a car available for their journey; (2) public transport users with a car available; and (3) private motorists. Group (1) could also be classified with respect to in-vehicle time, public transport mode, ticket type, journey purpose, etc. The groups had 474, 128 and 286 respondents, respectively. Each respondent played two `games', each including eight choices between two alternatives, each of which included several characteristics of a journey actually made. Group (1) played a different set of games from groups (2) and (3). Most of the study's results are displayed in tables, showing valuations for various passenger groups. It should be noted that, especially in SP studies, any valuations obtained empirically never provide the ultimate `truth'. Some results about travel time components (delay and adaptation time) and information are discussed, together with their practical relevance.
