Abstract:- In many emerging and developed nations, air pollution is a major issue. The largest source of air pollution in urban road networks is automotive emissions. In this regard, the current research illustrates the prediction of vehicular emissions from various kinds of vehicles seen on Vijayawada city's metropolitan highways. The Automobile Air Pollution Inventory (VAPI) model was used to assess and forecast vehicular emissions based on data collected in the municipality. This study examines the unbound emissions of Carbon Monoxide (CO), Hydro Carbon (HC), Nitrogen Oxides (NOx), Particulate Matter (PM), Carbon Dioxide (CO2), Benzene, 1-3 Butadiene, Formaldehyde, and Acetaldehyde from six distinct modes of transportation. The VAPI model findings revealed that there is a steady rise in emissions of each pollutant category each year, resulting in a decrease of air quality in the research region. The report also offers various mitigating actions to enhance the city's air quality in the next years.
