We analyze the complex travel behavior of workers who utilize public transit as part of their work tours (“transit commuters”). Here, complex travel behavior is defined in terms of tours, where a tour is defined as a sequence of trips and activities that begins and ends at the same location and a work tour contains at least one non-home, work activity. The objective of this study is to investigate how transit commuters link non-work activities as part of work tours under transit operational constraints. In particular, we identify dominant patterns of work tours made by transit commuters and analyze these tours using a set of activity-travel analytics and data from the 2017 National Household Travel Survey (NHTS). The primary insights are: (1) about 80 percent of work tours consist of 7 dominant patterns whereas the remaining 20 percent of tours demonstrate a total of 106 diverse and more complicated patterns; (2) half of the transit work tours are complex; (3) most simple tours are transit-only tours whereas most complex tours are multi-modal tours; and (4) transit use is more complex than the traditional home to work commute with a diverse set of choices at various stages of activity scheduling. While policies associated with public transit typically focus only on the journey to work, this study considers the complete set of trips starting and ending at home including intermediate non-work activity, which can provide insights for land use and transit-related policies to better accommodate the complex travel behavior of commuters who utilize transit.

我们分析了利用公共交通作为工作旅行一部分的工人（“通勤通勤者”）的复杂出行行为。这里，复杂的旅行行为是根据旅行定义的，其中，游览是指在相同位置开始和结束的一系列旅行和活动，而工作游览至少包含一项非家庭工作活动。这项研究的目的是调查过境通勤者如何将非工作活动联系起来，作为在过境操作限制下工作旅行的一部分。特别是，我们确定了通勤通勤者进行工作旅行的主要模式，并使用一组活动旅行分析和2017年全国家庭旅行调查（NHTS）的数据来分析这些旅行。主要见解是：（1）约80％的工作旅行由7种主要模式组成，而其余20％的旅行表明总共有106种多样且更复杂的模式；（2）一半的中转工作之旅很复杂；（3）最简单的旅行是仅过境旅行，而最复杂的旅行是多式联运；（4）公交的使用比传统的上班回家要复杂得多，在活动调度的各个阶段，公交选择的种类繁多。尽管与公共交通相关的政策通常只关注上班途中，但本研究考虑了在家中开始和结束的整套旅行，包括中间的非工作活动，这可以为土地使用和与交通相关的政策提供见解，以更好地适应利用交通的通勤者的复杂旅行行为。
