Abstract

On road vehicular traffic is the major responsible source for overall air pollution in an urban city. The emission of various pollutants and smog from tail pipe of vehicles are decaying the quality of air in urban cities. The present study accentuates the contribution of vehicles growth on air pollution observed in Tirumala town over the span of three years. The relative percentage increase of traffic volume and each pollutant category from the year 2015 to 2025 has been estimated. The relationship between the Annual Average Daily Traffic (AADT) and Annual Average Pollutant Concentration (AAPC) has been studied to examine the impact of vehicles growth on air pollution. The correlation analysis has been done between traffic volume and air pollutant concentrations to examine the impact of vehicles growth on air pollution. The time series analysis has been done for prediction of air pollution and traffic volume growth for the years 2020 and 2025. Based on the results obtained in the study, it is clearly evident that vehicles are the primary contributors for the total air pollution in Tirumala. This study also indicated that the air pollution level in Tirumala town in 2025 would be much more hazardous. The study also tried to provide some recommendations to reduce the pollution level in the coming years in Tirumala town. In this context, there is an immense need for the Pollution Control Board authorities to implement certain mitigation measures to improve the air quality in Tirumala town.
