Prediction of Vehicular Emissions in Vijayawada City

Air pollution is the severe problem in many developing and developed countries. In urban road networks, main cause for air pollution is vehicular emission. In this context, present study demonstrates the prediction of vehicular emissions from different types of vehicle observed on urban roads in Vijayawada city. Vehicular Air Pollution Inventory (VAPI) model has been used to estimate and foresee the vehicular emissions depend on information composed in the town. This work assess the releases of Carbon Monoxide (CO), Hydro Carbon (HC), Nitrogen Oxides (NOx), Particulate matter (PM), Carbon Dioxide (CO2), Benzene, 1-3 Butadiene, Formaldehyde and Acetaldehyde subjects unconfined from six dissimilar methods of transport. The results obtained from VAPI model showed that there is consistent increase in emission of each pollutant category every year which results in degradation of air quality in the study area. The study also suggests some mitigation measures to improve the quality of air for future years in the city
