Although the associations between the use of information and communications technologies (ICT) and individuals' daily travel and activity patterns have been extensively investigated for several decades, few studies have examined the amount of time spent using ICT, its implications on activity-travel behavior, and how such ICT-travel relationships may vary over time and according to residential location. This study takes a quasi-longitudinal perspective to explore how the amount of time individuals spend on the Internet for personal or non-work purposes correlates to their activity-travel for non-mandatory maintenance and leisure purposes, as well as how such associations evolve over a decade. More importantly, it examines how the role of people's residential locations in determining the associations between time spent on the Internet and travel has changed over time. Our approach utilizes two datasets from two major cross-sectional surveys in Scotland: the 2005/06 Scottish Household Survey (SHS) and the 2015 Integrated Multimedia City Data (iMCD) Survey, which were similarly structured and developed. To accommodate the multiple discreteness characterizing activity-travel choice and duration, the multiple discrete-continuous extreme value (MDCEV) model was employed to capture the Internet–travel relationships for the full sample and the urban, town, and rural sub-samples in both 2005/06 and 2015. Our findings suggest that use of the Internet for personal purposes increasingly tends to discourage rather than facilitate physical activity and travel for non-mandatory purposes over time, especially for those who spend high levels of time on the Internet (over ten hours per week). However, such Internet–travel relationships are generally weaker among people living in remote areas than those living in urban areas. While the relationships regarding maintenance activity purposes are significant for almost all levels of Internet users among the urbanites in both years, they were not significantly found at all among rural residents in either 2005/06 or 2015.

尽管信息和通信技术 (ICT) 的使用与个人日常旅行和活动模式之间的关联已被广泛研究了数十年，但很少有研究调查使用 ICT 所花费的时间量，以及其对活动-旅行行为的影响，以及此类 ICT-旅行关系如何随时间和居住地点而变化。本研究采用准纵向视角，探讨个人出于个人或非工作目的在互联网上花费的时间与他们出于非强制性维护和休闲目的的活动旅行之间的关系，以及这种关联如何演变十年。更重要的是，它考察了人们的角色 随着时间的推移，人们在确定上网时间与旅行之间的关联方面的居住地点发生了变化。我们的方法利用了来自苏格兰两项主要横断面调查的两个数据集：2005/06 年苏格兰家庭调查 (SHS) 和 2015 年综合多媒体城市数据 (iMCD) 调查，它们的结构和开发方式相似。为了适应表征活动-旅行选择和持续时间的多重离散性，采用多重离散-连续极值 (MDCEV) 模型来捕获全样本和城市、城镇和农村子样本的互联网-旅行关系2005/06 和 2015 年。我们的研究结果表明，随着时间的推移，出于个人目的使用互联网越来越倾向于阻止而不是促进身体活动和非强制性目的的旅行，特别是对于那些在互联网上花费大量时间（每周超过十小时）的人。然而，生活在偏远地区的人们的这种互联网-旅行关系通常比生活在城市地区的人要弱。虽然维护活动目的的关系在这两年的城市居民中几乎所有级别的互联网用户中都很显着，但在 2005/06 或 2015 年农村居民中都没有发现这种关系。
