Millennials, the demographic cohort born in the last two decades of the twentieth century, are reported to adopt information and communication technologies (ICTs) in their everyday lives, including travel, to a greater extent than older generations. As ICT-driven travel-based multitasking influences travelers’ experience and satisfaction in various ways, millennials are expected to be affected at a greater scale. Still, to our knowledge, no previous studies have specifically focused on the impact of travel multitasking on travel behavior and the value of travel time (VOTT) of young adults. To address this gap, we use an original dataset collected among Northern California commuters (N = 2216) to analyze the magnitude and significance of individual and household-level factors affecting commute mode choice. We estimate a revealed-preference mode choice model and investigate the differences between millennials and older adults in the sample. Additionally, we conduct a sensitivity analysis to explore how incorporation of explanatory factors such as attitudes and propensity to multitask while traveling in mode choice models affects coefficient estimates, VOTT, and willingness to pay to use a laptop on the commute. Compared to non-millennials, the mode choice of millennials is found to be less affected by socio-economic characteristics and more strongly influenced by the activities performed while traveling. Young adults are found to have lower VOTT than older adults for both in-vehicle (15.0% less) and out-of-vehicle travel time (15.7% less), and higher willingness to pay (in time or money) to use a laptop, even after controlling for demographic traits, personal attitudes, and the propensity to multitask. This study contributes to better understanding the commuting behavior of millennials, and the factors affecting it, a topic of interest to transportation researchers, planners, and practitioners.

据报道，千禧一代是二十世纪最后二十年出生的人口群体，与老年人相比，千禧一代在日常生活（包括旅行）中采用信息通信技术（ICT）的程度更高。由于ICT驱动的基于旅行的多任务处理以各种方式影响旅客的体验和满意度，因此千禧一代有望受到更大的影响。尽管如此，据我们所知，以前没有任何研究专门针对旅行多任务对旅行行为的影响以及年轻人的旅行时间（VOTT）值。为了解决这一差距，我们使用了北加州通勤者（N = 2216）来分析影响通勤方式选择的个人和家庭因素的数量和重要性。我们估计了显性偏好模式选择模型，并调查了样本中千禧一代与老年人之间的差异。此外，我们进行了敏感性分析，以探讨在模式选择模型中旅行时诸如态度和对多任务的倾向等解释性因素的结合如何影响系数估计，VOTT和在通勤时使用笔记本电脑的支付意愿。与非千禧一代相比，千禧一代的模式选择受社会经济特征的影响较小，而在旅途中进行的活动则受到更大的影响。两种车内的年轻人的VOTT均比老年人的低（15。即使在控制了人口统计特征，个人态度和多任务倾向之后，使用笔记本电脑的花费（时间或金钱）的支付意愿（减少了0％）和车外旅行时间（减少了15.7％），以及更高的支付意愿。这项研究有助于更好地理解千禧一代的通勤行为及其影响因素，这是交通运输研究人员，规划人员和从业人员感兴趣的话题。
