Abstract
Triggered by a vision of a next-generation in travel information services, this paper investigates travelers' needs for travel information. The role of travelers' perceived knowledge levels as a determinant of travel information needs is studied and distinctions are made between car-drivers and public transport-users. It was found that travelers' knowledge levels in terms of both their perceived reliability of their estimates for travel alternatives' attributes and their perceived resourcefulness in terms of route awareness are very important determinants of travelers' need for information. Several interesting relations between manifest factors and travelers’ knowledge and between travelers’ knowledge and their need for information are found and discussed in depth. Also, travelers' perceptions of reliability of travel information are investigated in depth; it is found that travelers' time related information needs are hard to fulfill with any information service, due to a so-called travel time information paradox.
