Integrated in- and out-of-home scheduling framework: A utility optimization-based approach

22nd Swiss Transport Research Conference, Ascona, Switzerland

Existing activity-based modeling predominantly focus on out-of-home activities in order to understand transport demand. In this research, we extend the state of practice in activity-based modelling by determining both in- and out-of-home activities in a single scheduling framework. This approach has two main benefits and applications: Firstly, it can capture the trade-offs between in-home and out-of-home activities. Secondly, in-home time-use patterns can be used to model high resolution energy demand, which can contribute to demand side management. Our work builds on an existing optimisation framework, which treats individuals as maximising their total utility from completed activities and incorporates multiple scheduling decisions simultaneously. The framework has been extended to determine the choice of location for activities such as work, study, and leisure. The approach is tested on a set of detailed daily schedules extracted from21st Swiss Transport Research Conference the 2016-2020 UK Time Use Survey data. The results show that the model is able to generate peoplesí daily activity schedules based on their preferences and constraints.
