1.      Generational differences in attitudes towards car, car ownership and car use in Beijing

北京對擁有及使用小汽車的代際差異

Abstract

In light of the recent trends in young people’s travel behavior and the importance of attitudes in influencing behavioral decisions, this study examines the generational differences in attitudes towards private cars and their interactions with car ownership and car use. Data are derived from a travel diary sample survey conducted in 2016 in Beijing, China, which include information about travel attitudes, car ownership, and car use. A multiple-group modeling framework capable of performing group comparison by allowing parameters to differ across different groups is applied to analyze the data. We find significant differences among different generations in terms of attitudes towards cars and their influences on car ownership, holding a driver’s license, and trips by cars. Young adults, in particular, show less favorable attitudes towards private cars and less prominent attitude-behavior associations than older groups do. They are also found to be less pragmatic about car use. Findings of this study shed new lights on the psychological factors on car-related choices and the significant differences between different generations, which are relevant for policies targeting on reducing car dependency and promoting a more sustainable lifestyle.

2.      Residential self-selection in the built environment-travel behavior connection: whose self-selection?

建成環境，居住自選擇及出行行為的研究新進展

Abstract: Residential self-selection has been acknowledged as a key issue underlining the link between the built environment and travel behavior. Existing studies often implicitly assume that residential choice is a decision of an individual and the influence of intra-household interactions is not considered. In reality, residential choice is a decision often made at the household-level involving more than one household members. Similarly, car ownership is usually a household-level decision incorporating views of different household members. In both cases, the travel related attitudes of more than one household members may play a role in the decision making. In other words, there is an issue concerning residential self-selection (similarly car ownership self-selection): whose self-selection? This paper makes an attempt to probe into this question by examining the self-selection issues concerning residential location choice and car ownership decision from the perspective of households, by incorporating the travel attitudes and travel behaviors of two household heads into an integrated self-selection framework. Data are derived from a household sample survey involving two-day activity-travel diaries conducted in 2016 in Beijing, China. Multivariate modeling results show that household members play different roles in household decisions with travel implications: in general husbands’ travel attitudes have relatively more influence in residential choice and car ownership decision than wives’. Nevertheless, wives’ travel attitudes have more power than husbands’ in explaining the commuting distances of both husbands and wives. Some distinct features of the residential and car ownership self-selections in the Chinese context are also identified and discussed in this paper.
