Residents' daily activity-travel mode with housing mobility is not only a response in short-term decisions, but also a result of factors such as behavior attitudes and habits in long-term daily life. This paper takes relocated residents as the study object, and analyzes the dynamic adjustment of daily activity-travel through external space-time constraints and behavior habits based on the theory of time geography and planned behavior, then a SEM is applied to explore the selection mechanisms of activity-travel on housing mobility. The result shows that effects of housing mobility to individual activity-travel behavior reflect on the adjustment of commuting patterns at first, and then on the non-commuting patterns. Specifically, the greater individual is subject to commuting constraints, the more easy to be adjusted by the way of commuting mode and starting time, and the adjustment of commuting will make a difference to non-commuting activity and then affect the intra-interactions mode of activities. Meanwhile, residents' daily travel behavior is influenced by the past travel behaviors or habits, and the dependence relation among the past behaviors can delivery to present activity-travel behavior.
