Impacts of Information and Communication
Technologies (ICT) on time use and travel
behavior: a structural equations analysis
Abstract The objective of this paper is to contribute an empirical study to the
literature on transportation impacts of Information and Communications Technologies
(ICT). The structural equation model (SEM) is employed to analyze the
impacts of ICT usage on time use and travel behavior. The sample is derived from
the travel characteristic survey conducted in Hong Kong in 2002. The usage of ICT is
defined as the experience of using e-mail, Internet service, video conferencing and
videophone for either business or personal purposes. The results show that the use of
ICT generates additional time use for out-of-home recreation activities and travel
and increases trip-making propensity. Individuals at younger age or with higher
household income are found to be more likely ICT users. The findings of this study
provide further evidence on the complementarity effects of ICT on travel, suggesting
that the wide application of ICT probably leads to more, not less, travel. The study
also demonstrates the importance of considering the interactions between activity
and travel for better understanding of the nature and magnitude of the impacts of
ICT on time use and trip making behavior.
