论文摘要
这项研究使用了1995年，2001年，2009年和2017年的美国全国旅行调查，将千禧一代与上一代（XERS Gen）进行了比较，从他们的汽车旅行跨越了不同的邻里模式。在16至28岁的年龄，千禧一代的每日个人车辆行驶时间较低，而汽车旅行较低，而Xers则比城市（高密度）和郊区（较低密度）社区的Xers较低。调整了社会经济，车辆所有权，生命周期，特定于全年和特定区域的因素后，这种差异仍然保持不变。此外，16至28岁的千禧一代的住宅密度与汽车旅行之间的关联比Xers一代的关联是扁平的，从而控制了上述协变量。在美国经济从经济衰退中恢复的时期，这些世代差异仍然是24至36岁的千禧一代。这些发现表明，在城市和郊区社区中，无论经济状况如何，美国的千禧一代都比上一代人的千禧一代低于上一代。在以后的生活阶段，这种差异是否仍然存在仍然是一个悬而未决的问题，值得不断关注。
Using U.S. nationwide travel surveys for 1995, 2001, 2009 and 2017, this study compares Millennials with their previous generation (Gen Xers) in terms of their automobile travel across different neighborhood patterns. At the age of 16 to 28 years old, Millennials have lower daily personal vehicle miles traveled and car trips than Gen Xers in urban (higher-density) and suburban (lower-density) neighborhoods. Such differences remain unchanged after adjusting for the socio-economic, vehicle ownership, life cycle, year-specific and regional-specific factors. In addition, the associations between residential density and automobile travel for the 16- to 28-year-old Millennials are flatter than that for Gen Xers, controlling for the aforementioned covariates. These generational differences remain for the 24- to 36-year-old Millennials, during the period when the U.S. economy was recovering from the recession. These findings show that, in both urban and suburban neighborhoods, Millennials in the U.S. are less auto-centric than the previous generation during early life stages, regardless of economic conditions. Whether such difference persists over later life stages remains an open question and is worth continuous attention.
