Telework and the day-to-day variability of travel behaviour: The specificities of Fridays

This study investigates the uniqueness of Fridays for telework in relation to commuting and non-work travel patterns. Utilizing Bayesian analysis on UK National Travel Survey data (2015-2019), it explores differences in trip frequency, distance, time, and CO2 2 emissions across days, particularly focusing on teleworkers versus other workers. The findings highlight Fridays as a distinct day for teleworkers, marked by a 20 % reduction in commuting and increased non-work trips, particularly during afternoons and evenings, compared to other weekdays and non-teleworkers. Key factors influencing these patterns include commuting mode, particularly private car use, and rural residency. The study concludes by considering telework's potential in reducing travelrelated CO2 2 emissions and its impact on public transport and local economies, especially post-COVID-19.
