住宅的自我选择已被广泛认为是一个重要的问题，在量化的住宅建成环境对出行行为的影响和自我选择效应的性质和幅度的经验证据已经报道。然而，人们可能会基于旅行态度/需求，不仅选择居住地点，还选择工作地点，汽车拥有量等。（关于工作地点、汽车所有权等的决定）旅行行为也可能受到自我选择效应的影响。然而，关于这些长期决策的自我选择在旅游行为文献中并没有得到太多的探讨。如果不考虑与其他长期决策相关的自我选择，则无法正确评估住宅自我选择的作用，因为它们通常是相关的。本文通过探索基于旅行的自我选择的多样性来解决旅行行为文献中的这一研究空白。我们共同研究了可能的自我选择的住宅位置，工作场所，通勤距离和汽车拥有量在一个综合的框架，考虑到这些决定之间的相互关系。数据来源于2016年在中国北京进行的活动旅行日记调查。我们根据受访者目前居住和工作地点的选择顺序将其分为两组，并使用结构方程模型进行比较分析。研究发现，自我选择存在于所有的长期选择中。居住地点和工作地点的选择是相互依赖的。因此，两种选择都通过另一种选择间接影响出行行为。
Residential self-selection has been widely considered as an important issue in quantifying the impacts of the residential built environment on travel behavior and much empirical evidence regarding the nature and magnitude of the self-selection effect has been reported. Nevertheless, people may be based on travel attitudes/needs to self-select not only residential location, but also work place, car ownership, etc. In other words, the impacts of long-term decisions other than residential location choices (e.g., decisions on work place, car ownership, etc.) on travel behavior may also be biased by the self-selection effect. However, self-selection concerning these long-term decisions has not been explored much in the travel behavior literature. The role of residential self-selection would not be properly evaluated if self-selections concerning other long-term decisions were not considered because they are often related. This paper addresses this research gap in the travel behavior literature by exploring the multiplicity of travel-based self-selection. We jointly examine the possible self-selections concerning residential location, workplace, commuting distance and car ownership in an integrated framework, taking into consideration the interrelationships among these decisions. Data are derived from an activity-travel diary survey conducted in 2016 in Beijing, China. We classify the respondents into two groups based on the choice order of their current residential and work locations and conduct a comparative analysis using structural equation models. It is found that self-selection exists in all long-term choices examined in the study. The choices of residential location and work place are found to be mutually dependent. Consequently, both choices have indirect impacts on travel behavior through the other choice.
