This study examines the factors influencing work duration, shopping, and recreation time, along with their variability, with a particular focus on demographic characteristics, employment status, household composition, and the built environment. The study utilizes data from the 2022 Halifax Travel Activity Survey, which collected detailed 24-hour activity logs from the respondents. Ordinary Least Squares (OLS) regression models were developed using the survey data to analyze the relationships between various independent variables and activity durations. The results reveal that individuals aged 25-65 generally work longer hours, while part-time workers and students report significantly fewer hours. Retired individuals exhibit greater variability in work duration, suggesting more flexible schedules, while students and part-time workers show less variability due to fixed routines. In terms of shopping and recreation, retirees and the unemployed spend more time on leisure activities, while students and households with children spend less time. License ownership and proximity to mixed land-use areas are significant factors influencing the duration and variability of activities. The findings underscore the importance of considering both intrapersonal and interpersonal variability when modeling travel behavior and emphasize the need for models that account for increased flexibility in work and leisure activities post-COVID.
