ABSTRACT

This paper presents an analysis of people’s time use patterns, incorporating the mediating role of ICT and personal networks on their daily activity-travel patterns, explicitly addressing the issue of activity fragmentation for social-based episodes. Implementing a seven-day time use survey, which includes temporal, spatial, and social characteristics for each activity, and using a theoretical framework based on current theory, a structural equation model was estimated to study these relationships. The results suggest a positive effect of ICT episodes on social activity interaction, activity fragmentation, and out-of-home social allocated time. We also found that ICTs encourage social trip generation only indirectly. Finally, those who had a social network physically close showed higher levels of fragmentation in their social episodes and less out-of-home social activity time. These results add evidence to this research stream, enhancing, and further clarifying ICT’s role in people’s daily activity behavior.

摘要

本文分析了人们的时间使用模式，将 ICT 和个人网络在他们日常活动旅行模式中的中介作用结合起来，明确解决了基于社交的事件的活动碎片化问题。实施为期 7 天的时间使用调查，其中包括每个活动的时间、空间和社会特征，并使用基于当前理论的理论框架，估计结构方程模型来研究这些关系。结果表明，ICT 事件对社交活动互动、活动碎片化和户外社交分配时间有积极影响。我们还发现，信息通信技术只能间接地鼓励社交旅行的产生。最后，社交网络密切的人在社交活动中表现出更高程度的碎片化，以及更少的户外社交活动时间。这些结果为这一研究流增加了证据，增强并进一步阐明了 ICT 在人们日常活动行为中的作用。
