An analysis of the dynamics of activity and travel needs in response to social network evolution and life-cycle events: A structural equation model.

Highlights: [•] The paper studies long term dynamics of social networks and activity travel needs. [•] Social networks evolve and activity travel needs change with life-cycle events. [•] The structural equation model takes path dependence effects into account. [•] It shows interdependencies between social network and activity travel dynamics. [•] It indicates existence of a threshold size of personal social networks. [ABSTRACT FROM AUTHOR]
