Abstract
The interaction between the use of Information and Communication Technology (ICT) and travel and transportation has been an important issue in transportation research. ICT may substitute work trips and enhances non-work travel. Particularly for social activity and travel behaviour existing studies suggest that ICT has complementary effects: ICT enhances social travel or increases efficiency in scheduling the activity by introducing flexibility into it or does both. However, with changing life events social network and associated travel may change for each ego-alter combination. These disaggregated effects ultimately bring in changes to the overall travel schedule of the ego and eventually to the local travel demand. In this paper we explore these dynamic effects. Using the event based retrospective data collected in 2011 in the Netherlands we developed a mixed logit model of face-to-face (F2F) social interaction frequency. We observe primarily a decline in social interaction frequency for existing ego-alter links. In addition to that we find evidence that ICT has a complementary interaction with social travel with some substitution effects particularly for stronger ties.
