Assessing the long-run impact of vehicular movement on air quality: An ARDL Approach

Research studies and policies have stressed the impact of private vehicles on the air quality and the significance of the public transportation. But, such studies have rarely proved the quantitative impact of the same. The present paper has established a long-run relationship between vehicular population and the air quality deterioration using time series data from one of the major metropolitan city of India, Bengaluru. Adopting the cointegration method: ARDL, the paper has provided quantitative impact of public transportation in improving the air quality of the city. The result is found to have significant impact on the transportation policies which can direct the urban planners in improving the public transportation in order to have positive impact on the air quality.
