Working from home (WFH) has significantly impacted telecommuters' activity-travel behavior and urban transportation systems, with potential to reduce traffic congestion, peak-hour pressure, and emissions. Early studies in the 1990s, when WFH began emerging as a regular work setting, identified it as a sustainable strategy to alleviate congestion and emissions. However, as WFH became more common, later research suggested its benefits might diminish due to more dispersed home locations and increased non-work travel, both enabled by telecommuting flexibility. The COVID-19 pandemic shifted WFH from a choice to an obligation, profoundly altering its impacts on activity-travel patterns. While numerous studies examined WFH during the pandemic, research on the effects of the post-pandemic hybrid work environment remains limited. This study uses a week-long activity-travel survey to explore how the hybrid work model affects trip-making behavior. Preliminary findings reveal that the post-pandemic hybrid work environment influences activity-travel patterns differently than the conventional pre-pandemic WFH. Notably, regular hybrid workers, splitting work evenly between home and office, show higher trip rates than occasional telecommuters, who primarily work from home. However, in general, higher rates of WFH throughout the week are associated with fewer trips and reduced travel distances as expected.
