Indeed, it is the need to perform activities spread over time and space that triggers the need for travel. Since the recent lockdowns associated with the pandemic, more and more individuals are considering performing several activities (including work) at home. The modeling of in-home activites requires an explicit modeling of intra-household interactions. We present a flexible modeling framework that allows to capture complex interactions, such as escorting activities, or activities whre a resource (such as the car) must be shared by several members of the household.
