As urbanization and environmental concerns rise, sustainable transportation is essential for cleaner cities, lower emissions, and equitable mobility. Active transportation (AT)—walking and cycling—supports healthier lifestyles, reduces environmental impact, and enhances urban livability. Despite extensive global research on AT behavior, a significant literature gap exists in understanding mode choice patterns across different regions, from Western countries to the Global South. While many studies have examined AT in developed nations, the unique socio-cultural perception, safety and security factors and infrastructural challenges of rapidly urbanizing cities in the Global South remain insufficiently explored. This study aims to bridge that gap by analyzing key factors influencing active transportation choices from 1,756 survey responses and Bayesian Belief Network (BBN) in Dhaka scenario, one of South Asia's fastest-growing megacities. The findings reveal that cultural norms, safety issues, and socio-economic conditions often outweigh infrastructure availability. Policymakers must adopt inclusive, safety-focused strategies that reshape societal perceptions and address region-specific barriers.
