Activity participation is influenced by many factors, such as the ones related to the built environment, but also to individual attributes. Herein we explore sequences of daily activities and travel employing techniques from the sequencing of events in the life course of individuals. Studying sequences of daily episodes (each activity and each trip) allows us to study the entire trajectory of a person's activity during a day while at the same time considering the number of activities, order of activities in a day, and their durations jointly. We applied this method to a sample of residents in the Metropolitan Area of Barcelona (RMB) in 2018, 2019, and 2020 Travel Surveys. We have focused on fragmentation analysis in activity participation, especially concerning gender, age, activity, and transportation mode. As expected, the survey from 2020 deserves a particular approach since activity patterns vary compared to surveys before the COVID-19 spread outbreak. In this respect, active transport shows to be particularly important that year. Overall, the results show that activity participation cannot be disentangled from gender, individual life-course, and the built environment.
