Abstract: The vehicular pollution has increased substantially in recent times. Indian mega-cities like Delhi which has distinctly been credited with dangerously high vehicular pollution levels. The present study has been undertaken aiming at pollution estimation for different transport corridors of Delhi city with a view to analysing the changing traffic composition trends and its impact on the levels of ambient air pollutants. From the study, it was found that Ring road (Safdarjung) had the highest concentration of CO and PM₁₀ as 3,066 and 422 μg/m³ while Auchandi Road bore the lowest concentration of the same as 193 and 23 μg/m³. Maximum values of 363 μg/m³ of NO_x at Maa Anandmayi Marg, 542 μg/m³ of PM_2.5 at ISBT Flyover and 42 μg/m³ of SO_X at Nizamuddin Bridge were reported in comparison to minimum values as 24 μg/m³ at Pusa Road, 53 μg/m³ at Sansad Marg and 2 μg/m³ at Auchandi Road respectively.
