Impact of Odd-Even Rationing of Vehicular Movement in Delhi on Air Pollution Levels

摘要

In this study, we investigate the impact of Odd-Even rationing of vehicles plying on the roads of the National Capital city of Delhi, India on air pollution levels by considering both residential and industrial areas of Punajbi Bagh, R.K. Puram, Anand Vi-har, Mandir Marg, NSIT Dwarka and Shadipur of the city and have analyzed its impact by employing event study technique and by utilizing daily data of NO_2, SO_2, O_3, PM_(10) and PM_(2.5). A ±15 day window has been considered for our analysis to assess the impact on air pollution levels pre-odd even rationing and post-odd even rationing and has statistically investigated whether this bold move by the State Government of Delhi has helped in the reduction of air pollution levels in the city or not. With the State Government considering implementing Odd-Even rationing permanently, the present study is intended to provide insights to policy makers to take an informed decision and also facilitate in implementing future policies for controlling air pollution levels in the city.
