Exploring Internet Activities Using Geo-visualization Technique

Recent studies have examined the interaction between people’s Internet use and their activity-travel patterns from both quantitative and qualitative perspectives. Although empirical studies have made great progress on generalizing the impact of the Internet on people’s daily activity-travel patterns, very few studies have successfully investigated why and how the observed patterns are generated. One reason for this is that the traditional space-time prism cannot accommodate important activity attributes besides space and time, such as activity types and location types. In addition, it is inappropriate to simplify Internet users’ space-time paths as single lines in that they can be “present” at different spatial scales simultaneously. Based upon previous theoretical frameworks, this study attempts to employ geo-visualization technique to explore the processes underlying people’s hybrid activity-travel patterns. An activity-Internet diary data set collected in Columbus (Ohio, USA) is used in the study. The data set provides information about respondents’ activities and trips in the physical world as well as their Internet activities. The research results enhance our understanding of the function of the Internet in people’s daily life, and consequently will be beneficial to future quantitative modeling of hybrid activity-travel patterns.
