社交与出行的相互作用研究综述

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.
