标题： Are Baby Boomers' Non-Work Trip-Making Behavior Different than Millennials? Lessons Learned from NHTS Data

摘要： 本文利用2017年全国家庭旅行调查数据，比较了千禧一代和婴儿潮一代的非工作出行行为。采用自助分段有序逻辑回归模型来捕捉不同世代群体之间的出行偏好和出行频率的变化，从而更稳健地揭示他们的非工作出行行为。研究发现，尤其是那些在家办公的千禧一代与较高的非工作出行频率呈负相关，而婴儿潮一代则与此呈正相关。模型结果显示，作为户主的女性千禧一代更有可能进行非工作出行，但居住在城市地区时可能性较低。相比千禧一代，婴儿潮一代中的拼车行为与非工作出行的关联性更高。这些见解可能对交通需求管理具有重要意义，因为出行模式的转变需要对基础设施投资和管理策略进行调整，以支持有效的长期交通规划。 显示英文摘要

摘要： This paper presents a comparison between Millennials' and Baby Boomers' non-work travel behaviors using data from the 2017 National Household Travel Survey. Bootstrapped segmented ordered logit models are employed to capture the variability in travel preferences and trip frequency across these generational groups, providing more robust insights into their non-work travel. Millennials, particularly those who work from home, are found to have a negative association with higher non-work trip frequency, whereas Baby Boomers have a positive association with higher non-work trip frequency. The model results show that female Millennials who are heads of households are more likely to make non-work trips but less likely when living in urban areas. Ride sharing among Baby Boomers shows a higher association with non-work travel compared to Millennials. These insights could have implications for travel demand management, as shifting travel patterns necessitate adjustments in infrastructure investments and management strategies to support effective long-term transportation planning.
