Abstract
This article investigates (determinants of) travelers' needs concerning travel information, based on a web survey filled out by 488 individuals. It aims at narrowing down three identified gaps in empirical literature available on this topic. Firstly, instead of focusing on the influence of manifest factors on travelers' need for information, such as trip circumstances, this article addresses the role of behavioral factors, in specific travelers' perception of their own knowledge levels. Secondly, instead of focusing only on currently available types of travel information, such as information on travel time and cost, this article also discusses travelers' need for a number of more advanced types of travel information, such as personalized early warning functions. Thirdly, instead of focusing on travel by car or transit, this study considers travelers by both modes simultaneously, and makes comparisons between these two groups. A number of new empirical findings are reported.
