社交与出行的相互作用研究综述

A review of research on interplay ofsocial relationship and travel behavior

在出行行为建模领域,社交关系对出行需求的产生、出行行为的选择等都具有重要影响,特别是在线社交关系、社交网站带来的信息传播深刻影响了人们的出行选择行为.本文从两个方面总结了出行与社交的相互复杂作用关系:一方面,社交关系在一定程度上决定了出行活动,如基于家庭的活动建模是以家庭为研究单位,家庭成员间购买食品、生活用品等活动具有互补性,机动车、自行车乃至出行预算等资源的使用既有互补也具备互斥性;另一方面,由于面对面交流是深层次社交关系形成和维系的必要条件,因此空间上的出行活动过程在一定程度上反映了复杂的社交关系网络形成及其动态演化.在此基础上,本文进一步综述了两者之间的相互影响以及结伴出行的最新研究进展,并根据目前的研究不足,从大规模面对面社交关系获取、有地理标签的数据集中提取结伴出行等方面提出了未来研究展望.

In the field of travel behavior modeling,social relationships have great impacts on the generation of travel demand and the choice of travel behaviors.Particularly,online social relationships and information spread by social networking sites deeply affect people’s travel choices.This paper will review the research progress of the interaction between social relationships and travel behavior from two perspectives.On the one hand,social relationships determine travel activities to some extent.For example,household-based activity modeling takes household as the modeling unit,for the reason that the activities of family members such as grocery or food shopping are complementary and the use of resources such as motor vehicles,bicycles,and travel budgets is both complementary and mutually exclusive.On the other hand,face-to-face communication is necessary for the formation and maintenance of significant social relationships;therefore,spatial travel activities reflect the formation and dynamic evolution of complex social relationship networks to a certain extent.Building on this foundation,this paper summarizes the interplay of social relationships and travel behavior,as well as the recent research progress of group travel behavior.Further,to address deficiencies of current research,future research prospects are proposed from the aspects of large-scale face-to-face social relationship acquisition and group travel data extraction from geo-tagged data sets.
