研究由于COVID-19的影响，在家工作、出行行为和汽车拥有量变化之间的相互作用
Examining the interactions between working from home, travel behavior and change in car ownership due to the impact of COVID-19
摘要：
COVID-19扰乱了社会，改变了人们的学习、工作和生活方式。然而，2021年春季的疫苗供应，导致马萨诸塞州的许多大流行前活动在2021年秋季逐渐恢复。本研究利用2021年秋季在大波士顿地区使用基于地图的调查工具收集的数据，探讨COVID-19导致的旅行行为变化，并调查导致这些变化的潜在因素。首先，结构方程建模技术的开发，以捕捉各种出行选择，包括在家工作，出行方式的使用和汽车拥有量的变化之间的相互作用。此外，态度因素，如风险认知和态度WFH被纳入框架来解释行为的变化。其次，采用离散选择建模方法研究2021年秋季通勤模式选择的变化。结果显示，在2021年秋季，人们更倾向于使用汽车通勤，对于那些在疫情期间购买汽车的人来说，他们更倾向于在现场工作。我们的研究结果可以为规划者和政策制定者提供信息，作为后疫情时代旅行需求管理决策的基础。
英文摘要：
COVID-19 has disrupted society and changed how people learn, work and live. The availability of vaccines in the spring of 2021, however, led to a gradual return of many pre-pandemic activities in Massachusetts in the fall of 2021. Leveraging data that were collected using a map-based survey tool in the Greater Boston area in the fall of 2021, this study explores changes in travel behavior due to COVID-19 and investigates the underlying factors contributing to these changes. First, a structural equation modeling technique is developed to capture the interactions between various travel choices, including working from home, travel mode use and change in car ownership. Moreover, attitudinal factors such as risk perceptions and attitudes towards WFH are incorporated into the framework to explain behavior changes. Second, a discrete choice modeling approach is taken to study shifts in commuting mode choices in the fall of 2021. The results show that in the fall of 2021, people became more likely to use their cars to commute, and for those who bought cars during the pandemic, they tended to work on-site more. Our findings can provide planners and policymakers with information upon which to base travel demand management decisions in the post-pandemic era.
