Assessing the Impact of Green Transportation Infrastructure on Urban Mobility and Air Quality in Developing Cities

Bello Hafisat Omodasola^1*

Abstract

The rapid urban expansion in developing nations has intensified vehicular traffic and worsened air pollution, presenting critical challenges for sustainable city growth. Green transportation infrastructure, such as Bus Rapid Transit (BRT) systems, non-motorized transport (NMT) pathways, and electric vehicle (EV) support systems has emerged as a vital strategy to enhance mobility while mitigating environmental harm. This study assesses the effectiveness of such interventions in three developing cities: Lagos (Nigeria), Nairobi (Kenya), and Dhaka (Bangladesh). Through geospatial mapping, mobility surveys, and longitudinal air quality data (2015–2024), the study examines how green infrastructure impacts urban commuting behavior and pollutant levels, particularly PM2.5 and NO₂ concentrations. The results indicate a strong correlation between green infrastructure deployment and reductions in traffic congestion and airborne pollutants, alongside improved commuter satisfaction and access equity. Despite these benefits, spatial disparities in implementation limit broader effectiveness. This paper advocates for inclusive and integrated transport policies that prioritize environmental justice, health outcomes, and urban resilience.
