The purpose of this paper is to review literature relevant for studies about the impact of information and communication technology (ICT) on transportation. The review will be used as a starting point for a research project at Swedish national road and transport research institute (VTI) and the department of economics, Uppsala university. To the relevant literature belongs of course empirical studies. But for the planned research it is maybe even more important to find suitable theoretical models. Therefore a quite comprehensive literature review of activity based transport research is included as well. Finally the report contains a brief description of data sources to be used in the project.
