Much of the literature shows a great interest in debating whether telework has a complementary or substitution effect on people’s travel demand. Relatively fewer studies analyze the modification effect of telework on individuals' activity-travel patterns. This study adopts a novel analytical approach to explore the influences of the duration of telework on sustainable travel. The empirical study builds upon a smartphone-based GPS travel survey conducted in the Puget Sound Region of Washington State. The merit of this research is twofold. We first investigate the threshold effects of the duration of telework and built environment characteristics on the shares of travel time spent riding public transit and engaging in active travel. The results can directly inform telework and land use policies. Then, we examine the synergistic effects of the duration of telework and the built environment on both travel outcomes. The findings suggest well-designed telework provisions could complement compact development policies aimed at shifting from automobile dependency to sustainable travel.

许多文献对远程办公对人们的旅行需求是否具有补充或替代作用的争论表现出极大的兴趣。相对较少的研究分析了远程办公对个人活动-旅行模式的影响。本研究采用新颖的分析方法来探讨远程办公持续时间对可持续旅行的影响。这项实证研究建立在华盛顿州普吉特海湾地区基于智能手机的 GPS 旅行调查的基础上。这项研究的优点是双重的。我们首先研究了远程办公持续时间和建筑环境特征对乘坐公共交通和积极出行所花费的出行时间比例的阈值影响。结果可以直接为远程办公和土地使用政策提供信息。然后，我们研究了远程办公时间和建筑环境对两种旅行结果的协同影响。研究结果表明，精心设计的远程办公条款可以补充旨在从汽车依赖转向可持续出行的紧凑发展政策。
