Abstract:

Study on the interaction in one family is an important perspective in the interpretation for individual activity- travel decision. Usually, people's activity- travel pattern is not a simple output of individual choice behavior and often influenced by surrounding environment, resources, and/or decisions of other people’s activity-travel. In fact, every person plays a fixed role in their family and he/she will make the travel decisions considering the needs of family members. So this paper aims to concern the interactions that born in the multi- activity or multi- person of the urban unclear families and proposes the new concepts of “activity restrict degree”and“activity constraint niches”to quantify the degree of space-time constraint under the view of time geography. A structural equation model is used to analysis the intra-household interactions though people’s activity-travel pattern in workdays. The result indicates that the linkage between family members is the behavioral responses while compared the constraints between individual and other family members. The household interaction constraints not only influence the selection of individual travel, but also reflect in the delivery of household activity model among the different people. Furthermore, the essence of interactions is a reasonable adjustment by household company or mutual aids and then to find out a more efficient pattern to meet the demand of household activities.
