The reconfiguration of urban transportation system has emerged at the forefront of population-wide interventions to tackle physical inactivity. However, the effectiveness of these interventions remains understudied, especially in developing countries. Using self-reported physical activity data from pre- and post-intervention periods, this study examines the impact of bus rapid transit (BRT) and Complete Street implementation on walking and cycling levels of catchment area residents in Mexico City. Propensity score matching is applied to control for sociodemographics when evaluating intervention effects on walking for transport, walking for recreation, and cycling for transport. On average, individuals living in post-intervention conditions tend to achieve 29 min more of walking for transport per week. However, the intervention effect on cycling for transport is insignificant. Using clustering techniques, intervention effects are evaluated across different sociodemographic groups. Women with low education experience the greatest increases in walking for transport. Sociodemographic clusters characterized by higher education experience improvements in recreational walking. Overall, BRT implementation and streetscape improvements enhance physical activity, specifically walking; and the impact of these interventions vary across different sociodemographic subgroups.
