Abstract

Delhi has witnessed an alarming rise in air pollution, primarily attributed to transportation emissions. This study evaluates the impact of transportation on Delhi’s air quality between 2019 and 2024, using Geographic Information Systems (GIS). Key pollutants including PM₂.₅, PM₁₀, NO₂, SO₂, and CO were spatially analyzed to assess their concentration in correlation with traffic density and seasonal patterns. GIS-based mapping identified major pollution hotspots along key roadways and commercial corridors. The COVID-19 lockdown in 2020 served as a natural experiment showing a sharp AQI improvement. The study concludes with recommendations for GIS-integrated urban planning, stricter vehicle regulations, and sustainable mobility solutions.
