Research highlights ► An agent-based approach to simulate the dynamics of location choice-sets under social learning. ► A framework to model choice behavior, distinguishing habitual choice, exploitation and exploration. ► A framework to model information exchange and aspiration adaptation in social networks. ► Numerical simulation results of various scenarios demonstrate the model properties.

    Abstract Activity-based analysis has slowly shifted gear from the analysis of daily activity patterns to the analysis and modeling of dynamic activity-travel patterns. In this paper, we address one type of dynamics: the formation and adaptation of location choice sets under influence of dyad relationships within social networks. It extends the dynamic model developed in earlier work, which simulates habitual behavior versus exploitation and exploration as a function of discrepancies between dynamic, context-dependent aspiration levels and expected outcomes. Principles of social comparison and knowledge transfer are used in modeling the impact of social networks through information exchange, adaptations of spatial choice sets and formation of common aspiration levels. We demonstrate model properties using numerical simulation with a case study of shopping activities.
